Loowit Trail

The Loowit Trail circumambulates Mount St. Helens, dropping into and climbing out of deep gullies left by the eruption of St. Helens and its subsequent debris flows. This hike is very challenging, with sparse camps, little water and some sketchy sections of loose pumice. Since the eruption denuded the slopes of the mountain, you’re almost always in sun, so make sure you wear your hat and bring sunscreen. It is all too easy to get a severe sunburn on these slopes.

With those cautions in mind, you’ll fully appreciate the stark, otherworldly beauty of the blast zone. Vast fields of pumice gouged with deep gullies frame the gaping immensity of the mountain.

There are multiple points where you can access the Loowit, here are four of the most commonly used access points. (If you want a taste of the Loowit without the full meal deal, each of these hikes is a great way to sample the mountain.)

Windy Ridge
Follow the Truman Trail (#207) for approx. 3 miles, then take the Windy Trail (#216E) for another 1 mile to the Loowit (#216). This route will take you closest to “The Breach” and Loowit Falls. Note that camping is not allowed in the blast zone which includes the northern portion of the mountain between the South Fork of the Toutle River and Windy Pass.

Ape Canyon Trailhead
Park at the Ape Canyon Trailhead and go 5.5 miles on the Ape Canyon Trail (#234) to the junction with the Loowit (#216). Turn right (north) and hike another mile or two across the spectacular Plains of Abraham. Note this route is very popular with mountain bikers.

Climber’s Bivouac
Take the Ptarmigan Trail (#216A) 2 miles to the junction with the Loowit (#216). Turn left or right to experience the Loowit as it skirts the treeline along the volcano’s southern flank.

Blue Lake Trailhead
Follow the Toutle Trail (#238) for about 3 miles. Ascend the Sheep Canyon Trail (#240) 2.5 miles to the Loowit. You can make a nice lollipop loop by following the Loowit another 2.5 miles north to its intersection with the terminus of the Toutle Trail, then following the Toutle Trail approx 5 miles back to the Blue Lake Trailhead.

Circumnavigating Mount St. Helens
Some recommend starting from the south at Climber’s Bivouac while others chose to start on the NE side from Windy Ridge. In either case you need to plan on crossing the blast zone in one push as camping is prohibited between the South Fork of the Toutle River and Windy Pass. Since the most rugged section is on the west side where major washouts require extensive detours and/or scrambles, plan your trip to hit those sections when you are relatively fresh.

Although each year hikers do complete the Loowit, others have turned back unable to find safe passage through some of the gullies. Since conditions change so frequently and people’s route finding ability and tolerance for risk vary, it is impossible to predict if the circumnavigation is “doable” at any given time for any hiker.

This route description is for a counter-clockwise circumnavigation hike starting from the north side where the Windy Trail (#216E) meets the Loowit.

Your first seven miles will afford near constant views of denuded slopes as you cross the blast zone looking into “The Breach”. As you come around the mountain to the NW, the route drops into the valley carved by the South Fork of the Toutle. Here the trail is frequently obliterated by the river and sliding loose rock and pumice. Crossing this gully is the first of three major wash-outs on the route.

Continuing on the Loowit, the trail climbs up into remnant old growth forest on Crescent Ridge, and then enters a zone of burned trees and flower-rife meadows. You’ll enter subalpine forest, the trail climbing and falling until it again ascends to timberline near 4,700 ft. About a ½ mile beyond the junction with the Sheep Canyon Trail the Loowit was obliterated by a washout leaving a huge chasm with near vertical walls in its place. The Forest Service completed a bypass route that adds another few miles, but it is much safer than attempting to scramble through the massive gully.

Next, you’ll reach the junction with the Butte Camp Trail #238A. You can drop steeply along this trail—roughly 800 feet—to Butte Camp, if you need to make camp.

Most of the trail from here on in is rugged as it runs along lava beds to the junction with the June Lake Trail. For a pleasant campsite, follow the June Lake Trail (#216B) ¼ mile to its namesake lake. Continuing around the SE side of the Mountain you will encounter the 3rd major washout on the Loowit at Muddy Creek. It is approx. 4 miles from the June Lake Trail junction. Like the previous two washed out sections, the steep canyon walls and loose rock make it difficult and dangerous to scramble through the chasm. Currently there is no bypass route. However WTA volunteer Backcountry Response Teams are scheduled to restore this section in 2010.

You’ll traverse more lava on the 4.75 miles to the Ape Canyon Trail, and finally have 4 miles of relatively smooth trail across the Plains of Abraham, then up Windy Pass and back to the intersection of the Windy Trail (#216). From there you’re on familiar terrain following the Truman Trail (#207) back to Windy Pass.
Driving Directions:

Take FR 25 just outside of Randle, take FR 99 16 miles to its end at Windy Point. Walk the gated service road signed “Truman Trail No. 207” toward Mount St. Helens for two miles until you descend into a dry arroyo. From here, take the Windy trail #216E until you reach the Loowit at about 4,500 feet.

It was cloudy in Seattle; so, we started south. The clouds started to part as we approached Windy Ridge Parking lot in the Mount St. Helens Recreation area. While the road is paved, it is a windy and slow drive from route 12. The first 2 miles are on an old road and go easily down hill. This connects with the Truman trail and starts over the toward the Plain of Abraham. The trail is easy going and my vision was downward to see how Mother Nature was healing herself. Pearly Everlasting was everywhere and in bunches - more than I have seen anywhere. Lupine, Penstemon and Paintbursh were spread here and there. The trail has up and downs through the gullies. Soon views of Spirit lake come into view and then the lava dome in the crater. We went about 2 miles and had lunch. We decide to loop back on go up the Loowit trail by the falls and then back to the Truman trail on our way out. I like this part better - the view over the Plain and Lake were better. I felt that I was looking at Mother Nature undressed - like most of us, she looks better dressed. The bare rock, open gullies, little color and wrinkles are all there. I hope I can come back in another 20 years to see how it has changed. This is an easy loop of 9-10 miles with may 1000 feet elevation gain. No spectular views but a real feel for how the earth heals.

St. Helens under a full moon! (waxing)

This was a superb way to enjoy the St. Helens blast area during mid-late summer. The weather for this trip was partly cloudy, which helped to cut the heat, and made for spectacular sunsets and moon gazing.

I arrived at the end of the Windy Ridge road at about 7 P.M. - after most of the tourist throngs had left. Hiked to the Loowit trail and dropped my pack to catch the sunset near Loowit Falls (leaving a little bit earlier would have been wise in order to make it to the Falls before dark.) I returned to my pack and climbed to Windy Gap directly towards the rising moon.

The trail here, as well as descending on the other side, definitely shows the wear of a rapidly changing geology - nothing to extreme, but certainly something to be careful of. The trail would still be education for youngsters, but they should be somewhat experienced and respectful. This trail is probably a good place to teach these various lessons.

I bivy'd at Windy Gap, on the boundary of the restricted zone. There would also be some good camp areas to on the Shoulder point just to the East of the Gap - right along the restricted area Boundary. This area is a bit more private, larger, and offers adds the bonus view of Rainier to the Adams and Hood mix.

The moon over the desertscape of St. Helens and the clouds was absolutely magical. So much so I feel right asleep, never to catch the moon directly over St. Helens - and free of clouds.

I returned to Windy Ridge via the Plains of Abraham. The final section of the trail traverses the ridge crest and would be a lightning risk in moderate-severe weather. Today a rainbow was spotted over the main St. Helens mud flow just as approaching the ridge. Unfortunately it was gone by the time I arrived at the Ridge top.

I got back to the car by 10:00 a.m. after covering approximately 10 miles of desolate moonlit beauty. It appears that their may be an option to extend the loop via Ape Canyon, but as there appears to be some new trail construction, the tourist descriptions were contradictory and/or ambigous, and my climbers 7.5' topo didn't cover the area I decided not to explore. The loop continues from Ape Canyon to Swift creek and ends with a hot and dry climb back to Windy Ridge.

On my loop water was available on the trail to Loowit Falls and also on the Plains of Abraham. Both of these creeks were small enough to dry up in a drought year or from changing geology. Windy Gap is a dry camp. Flowers were ok-good. There was something that appeared to be a deserty lupine kind of thing growing all over the place on mudflow which was interesting. It may well be just Lupine adjusting to the deficient soil. No bugs.

The Toutle and Butte Camp Trails are a nice way to access the Loowit Trail, although a long drive from civilization. From the Olympia area, it is about a 3-hour drive, mostly on paved roads. Take Hwy 503 from I-5 towards Cougar. Past Cougar, Hwy 503 becomes FR 90. A short way pass the crossing of the Lewis River Spillway, is an intersection with FR 83. Follow 83 to the Sno-Park and take a left towards Red Rock Pass (this road is gravel). You'll pass the access road to the Climber's Bivouac on the way. Since we stayed overnight at Beaver Bay Campground (Pacific Power, fee) it was about an hour drive one-way.

From the small parking lot at Red Rock Pass, the Toutle trail immediately climbs up and through an ancient lava flow on good trail, with views of Mt. St. Helens. Then the trail enters open woods, crossing a couple of old road/trails which are used in the winter as XC ski routes. The Toutle Trail finally turns west, while the Butte Camp Trail begins a gradual climb towards the Loowit Trail.

Most of the trail passes through woods, with brief openings, including a pretty meadow at Butte Camp. There is a spring-fed stream here. We saw some late flowers here, also, including yellow and pink monkeyflower and willow herb. From here, the Butte Camp Trail climbs a series of switchbacks through woods and then along a dry open slope. Views open up as the trail climbs to a cliff line and finally tops out at the junction with the Loowit Trail. From here, only climbers can go cross-country further up the mountain. For hikers there is the decision whether to go right or left to sample the delights of the Loowit. Or choose to just enjoy some late summer sunshine as we did. Views to the south include Mt. Hood and the desolate slopes of St. Helens loom above. The area is very open and alpine, with heather and grass meadow interpersed with volcanic rock and tiny trees, one of the prettier areas along the entire Loowit.

There were a few minor blow-downs across the trail, but no impediments to hikers. The tiny creek at Butte Camp is the only water available on the route this time of year. There was no wind while we were there, which can be an unpleasant feature of the Loowit due to the ash and sand in the area. It is an enjoyable hike for people wanting a closer look at some of the volcanic features of Mt. St. Helens.

Loowit Trail #216 Loowit is the name of a beautiful young girl who became a beautiful mountain, Mt. St. Helens. The trail that circles the mountain is only 27 miles long, but as difficult and changeable as only a trail through active volcanic territory can be.

Our group consisted of Doris (leader extraordinaire), Ray, Maxine, Sonny, Ishmael, Mary Jo, Gaylord and myself. We started our four-day adventure from the Windy Ridge parking lot, at the end of FR 99. The early morning fog was lifting, revealing the ash and pumice-covered slopes of the mountain. Spirit Lake lay below, beautiful and blue, with its floating log burden. To access the Loowit Trail, we walked down a stretch of the Truman Trail, an old road now only occasionally used by scientific teams accessing the Pumice Plains. On the way to the Plains, we passed the trailhead for the Abraham Trail. We passed a parking lot and the junction of the Truman Trail with the Loowit Trail and started on our way.

The first day was spent crossing the Restricted Zone. No camping is allowed and hikers must stay within a 10-foot space near the trail. There is no shelter, no trees, and no shade. The zone can be blistering hot, dusty, windy and dry. Few reliable water sources are available. We had to hike nearly 12 miles that day to reach our first available campsite. The Pumice Plains look flat from Johnston Ridge, but are anything but smooth. There are frequent gullies to cross as well as active alluvial fans, filled with debris, mud, silt, and rocks. We passed by beautiful carpets of tiny alpine lupine, as well as stark rocky washes devoid of vegetation. In one startling oasis, we discovered a garden of pink monkey flower and hardy willows hugging the edge of a creek, which sprang full-grown from the side of the mountain.

After struggling over the uneven surface of the Pumice Plains, we climbed to the heights of Studebaker Ridge, with its views of Spirit Lake, Mount Margaret and Castle Ridge. The mountain loomed to the east. The trail then dropped down into the difficult gully of Studebaker Creek and climbed again to a ridge above the South Fork Toutle River. The South Fork’s canyons were scoured by the mudflows of the 1980 eruption and were very deep. We dropped down the steep slope on switchbacks, crossing sloughing banks, soft and deteriorating tread and finally reached another oasis of young bushes, where we had to beat our way through thick brush to reach the river’s edge. Some of us gracefully rock-hopped across the Toutle. I splashed my way through a shallow ford and we all scrambled up the difficult steep loose rocky bank.

Our first camp was located off the Loowit Trail, on the Toutle Trail, next to a stream. The camp was located in old growth forest and well sheltered. Stats: 11.7 miles, 1,610 feet gain.

On the second day we were greeted by heavy drizzle, soaking tents and clothing. We beat our way back to the Loowit and began the relentless climb up the trail to reach Crescent Ridge. On a clear day, there are views of Johnston Ridge and Clearwater Visitors Center, as well as the deep colorful canyons of the South Fork Toutle. The mountain looms above it all. The trail passed through a bit of forest and then reaches the blast zone, now covered with thick huckleberry, thimbleberry, maple and alder, young fir and hemlocks and tall bleached skeletons of the pre-1980 forest. Soon we came to the junction with the Sheep Canyon Trail and about a 1/2 mile beyond, another of our major challenges, a huge washout at the Blue Lake mudflow gully. After gasping at the depth of the gully, our party elected to hike down and around it, which we did quite successfully. Even then, the steeply sided slopes were still a challenge.

Soon we reached the junction with the Butte Camp Trail. The terrain was quite beautiful, passing through open grassy meadows with rocky outcrops and a pumice plain. There were few trees. Mt. St. Helens has few forests since there has been so much recent volcanic activity with mudflows and pyroclastic eruptions constantly disturbing any attempts for trees to establish a foothold on its slopes.

Near the junction of the Butte Camp Trail, we encountered our first lava flow. The trail through it and the preceding ones were vague. We followed a wavering line of tall poles and sometimes gravel path through lumpy black boulders big and small. Hopping from one uneven rock to another with a full pack was quite an exhausting experience. After the lava, we crossed another treacherous gully and then another large lava flow. Beyond that there was thick alpine forest, through which the trail quickly descended. Several large trees were down across the trail, requiring us to either climb over, under or go around the barriers. Then we came upon the Ptarmigan Trail, the summer route for mountain climbers. There we took a well-deserved break and talked to a couple of groups on their way down the mountain. Then past the junction, we climbed back up into another lava flow to reach Swift Creek and Chocolate Falls, our second campsite. We were exhausted. Stats: 11.1 miles, 2700’ gain.

The third day dawned mild and cloudy, low-hanging clouds blocking any views, but keeping the temperatures at a comfortable level. We began our day climbing the Loowit over a lava flow with good tread. Above us loomed the Worm Flows Buttress. We climbed the open, rocky slopes and reached an area with good views. The clouds broke up enough to give us glimpses of Mt. Adams to the east and Mt. Hood to the south. On the mountain slope above was the Shoestring Glacier. There was another nasty gully to cross, but nothing to approach our next major obstacle, the crossing of the Shoestring Canyon and the Muddy River. This area was extremely daunting. The trail barely exists and any detours would be extremely long. We had to cross.

Footing was treacherous, but we climbed down the steep loose slopes carefully, successfully reaching the bottom of the canyon. We climbed up and over the island and dropped down into another ravine. I needed help with my big pack. Then we climbed up the trace of trail left in the sloughing slope. Near the top, I slipped and slammed into the side of the canyon, digging into the loose soil with fingers and toes. Fortunately for me, Maxine and Ray grabbed my pack, and then proceeded to hang on to me as I scrambled on hands and knees over the edge of the gully and onto flat ground. I was a bit dirty and scratched, but alive and grateful for my companions’ steady thinking. With everyone safely over the Shoestring, we proceeded on to the junction with Ape Canyon Trail, peeking briefly over the cliff into the scoured canyon below. We then completed the day’s hike by reaching the Plains of Abraham where we set up camp next to a stream. Stats: 7.6 miles, 2,060’ gain.

Our last night was very windy. Few of us got much sleep. At one point, I awoke to see the moon rise golden to one side of Mt. Adams and the Milky Way strung out like diamonds above. At dawn, the wind had not abated and it was a chore to break down camp. We chose to hike out via the Abraham Trail, as our leader, Doris, noted that the Windy Pass portion of the Loowit was difficult and steep. None of us needed to prove ourselves on more treacherous trails.

We crossed the Plains of Abraham, passing tall cairns of black rock and fields of blooming lupine and penstemon. After the junction with the Abraham and Loowit trails, we passed through a wash strewn with black rocks and climbed up gentle grades onto Abraham Ridge. The trail looped around the slopes through beautiful flower gardens and then climbed up to the top of the ridge, fully exposed to the strong winds. The clouds were descending too, bringing thick drizzle to dampen everything. The final mile or so of the ridge, we hiked along a narrow strip of trail on the knife-like summit, fighting all the while with strong gusty winds that threatened to throw us off. Finally we reached the security of the old roadbed of the Truman Trail, with 1.7 miles to hike back to the parking lot. It was with great relief and joy that we left behind the challenges and tribulations of the Loowit Trail. It was a great adventure, but none of us was eager to do it again very soon. Stats for the final day: 5 miles, approx. 700’ gain.

This trail is definitely ONLY for very experienced backpackers and those who feel confident scrambling over loose steep slopes and uneven rock surfaces. The Loowit continually challenged us in every way and every day. We were mostly fortunate that the weather was cooler, because it is normally quite hot this time of year. And while we found plenty of water, it can not be counted on every year. The mudflow canyons were particularly dangerous and difficult to cross. Personally I feel very lucky to have survived the ordeal and would never attempt such a hike without a very strong, experienced group to back me up. It is thanks to them that I can write this report.

I’m going back to the Loowit, but only on day hikes. The country is fabulous, raw and wild and deserves every respect for the grand forces of Nature and the cycle of life dictated by a young and vigorous volcano called Mt. St. Helens.

It was raining when I began my drive from Tacoma, but soon resolved to high overcast as I arrived at Beaver Bay on Yale Lake to meet my group. We drove up Road 81 and then to the end of FS Road 8123 to the Sheep Canyon Trailhead. This area is scarred both the depredations of man (clearcutting) and nature (mudflows). The trail starts up the hill through a lovely forest. Then at about 1/2 mile we came to a junction with Trail #238 which crosses Sheep Creek on a bridge. Climbing over a ridge it comes out above the S. Fk. Toutle River. The ridge across the river was shaved clean by superheated gases and the river bed churned with masses of melted snow and mud. The river has already carved down through soft layers. Vegetation is coming back, with pioneer plants, alder, lupine, huckleberry, fireweed, penstemon, etc., predominating. We came to the junction with the Loowit Trail, a route that circumnavigates St. Helens. This trail is very rough in places, but we traveled on a part with good grade and views. When we reached a high spot on Crescent Ridge, we could see Johnston Ridge Observatory and beyond a corner of Coldwater Lake, the Visitors Center and strangely naked peaks in the distance, devoid of their tree cover. The huckleberries along this stretch of our hike were unbelievable, huge, juicy and thick. We had lunch while admiring views of the mountain, which was still mostly in the clouds. Next, we traversed the Loowit Trail back to its junction with the Sheep Canyon Trail and back to the cars. We counted ourselves lucky to have avoided rain during the hike. Except for some slide areas, the thread was in great shape. One bridge on lower Sheep Canyon Trail is broken but passable. The bridge over the main creek is in great shape. The loop is about 7 miles and 1900' gain. Beware! Bow hunters are wandering around in the mountains now.
