Coal Creek Falls

Water, water everywhere and quite a drop it takes! Cougar Mountain's Coal Creek Falls is the primary attraction here, but it's the water underfoot that really makes the area special. Such abundance helps keep the forest green and fragrant, with wildflowers in season--and abundant summer mosquitoes. Come in November through May, when the nights are too cold for these pesky biters and the falls are full of runoff. In the spring you'll find skunk cabbage, and through the early summer you'll enjoy plump, juicy salmonberries. And at the end, you'll enjoy the cool cascade of Coal Creek Falls.


From the trailhead, head up toward Red Town. The route you want veers left onto Cave Hole Trail. Once upon a time, mules pulled wagonloads of coal down this trace, and later, as the coal veins played out, folks used it as an access route to another easily accessible fuel source: firewood. Today's trail uses that same old track.

As you climb away from the old Red Town site, you'll notice areas where the ground seems to have slumped in on itself--these are the cave holes that give the trail its name. The holes formed when miners pushed their underground extractions too close to the surface, leaving a void that eventually caved in, creating a "cave hole" in the ground above.

Less than 1 mile after leaving the trailhead, you'll find the Coal Creek Falls Trail leading off to the right. The path meanders around the upper slopes of Curious Valley before slanting down into a small gulch carved by the tumbling waters of Coal Creek. Here, about 1.25 miles out, you'll find the falls.

Coal Creek Falls can be spectacular during the rainy season of January-March, thundering down the rocky chute. Venture out during a particularly cold spell and you'll find marvelous ice sculptures formed by the splashing and spray from the falls. By midsummer, the falls usually shrinks to nothing more than a small splattering of dribbling streams between the rocks.

Hiked today with a good friend, Pandora. She let me pick the trail. I decided on Cougar Mt. Red Town Trailhead. We hiked 4 hours total and did a good loop To coal creek falls then far country lookout and falls (not much of a view or falls). Coal Creek was much better. Then headed back via De Leo Wall Trail, we skipped the viewpoint didn't look too grand. Hopefully we didn't miss something wonderful there. Then we stopped in the Meadow restoration area and saw some beautiful lillies that were flagged. Great day to be out, could not have asked for better weather. Not too many people on the trail. Well signed area with maps at the trailhead. Lots of history in this area, we even got a mini lesson from some guy on the trail about the coal miners settlement, very interesting. He was very proud of ""his area"" as he lived close by. We saw young, old, horses, dogs all enjoying the trails today. I will be back to explore more of this area.

I took this 7.5 to 8.0 mile loop in Cougar Mt. Park as a tune up hike for several planned summer hikes including a traverse of Rattlesnake Ridge.

Saturday turned out warm and pleasant and a great day to be out. My allergies which had been bothering me did not affect the hike which took about 3.5 hours with two breaks at Longs Peak and Far Country Look Out.

Lots of people were out with pets, trail running, or their children. The most notable parts of the hike were low land flowers and a deer family on the Cave Hole trail. The attached photos are of Skunk Cabbage near Doughty Falls and Phlox on the Coal Creek Falls Trail. Coal Creek Falls were as stunning as I have ever seen them.

All an all a great trip, with about 1200 to 1400 feet of elevation gain and loss. Trails were generally dry with some mud holes particularly on the horse use trails.

Sunday's weather wasn't quite as glorious as Saturday, but I had free time for a hike and was looking for something close-in, so Cougar Mountain it was. If you're looking for a nice outing in the foothills, Cougar doesn't have quite the crowds that Tiger Mountain has. And you can get to the trail by bus or bike, making it an especially ""green"" hike! See the end of the report for more details.

The maze of trails is confusing at Cougar, so be sure to pick up one of the printed maps at the trailhead or download one from here before you go.

I started at the Red Town Trailhead just off the Newcastle Golf Club Road. I started up the Wildside Trail (W1) with a brief detour to the old mine shaft and kiosk on the coal mining history of the are just a few hundred yards up the trail. Then continuing up W1, saw plenty of wildflowers in bloom right now. Saw my first trilliums of the season, plus evergreen violet, red-flowering currant and miner's lettuce. The bleeding heart should be in full bloom in about a week.

I then turned off to the De Leo Wall Trail (W9) and the forest changed from western red cedar, ferns and alder to salal, Douglas-fir and madrona. The viewpoint was a pleasant spot for lunch although I preferred the view of the madronas and pink flowers of the currant bushes to the vantage on Renton and the nearby suburbs.

Heading back down, I branched off on the Indian Trail (W7) and took a right uphill on the Quarry Trail (C6). Then it was left on the Coal Creek Falls Trail (C4), to the falls, which are running quite nicely now. Then it was down the Cave Hole Trail (C3) to the trailhead. All told, the hike was about 2 hours and approximately 5-6 miles of hiking. Trail was in good shape, only one blowdown and a few patches of mud.

And the neat thing was: I didn't burn a drop of gas to get to the trailhead. This is a great hike to bike or bus to!

From Seattle, you can take the Sound Transit 550 to the South Bellevue Park & Ride, then connect to the M240, which heads out on Coal Creek Parkway. Request a stop at Coal Creek and 119th. You'll have to hike an additional 4 miles round trip on the Coal Creek Trail to get the Red Town Trailhead. Or pop you bike on the bus and complete the trip along Newcastle Golf Club Road to the trailhead.

Biking from Seattle requires about 2 hours one-way and it's a very pleasant ride. I found my way to the paved I-90 trail, crossed the lake, then headed south on the Lake Washington Trail. Cross over I-405 on Lake Washington Blvd. and head up over the hill on SE 68th St. Take the Newcastle Golf Club Road (which becomes Newcastle-Coal Cree Road) to the Red Mountain Trailhead. On the return, head back on Newcastle Golf Club Road to Coal Creek Parkway, then you can take the wide bike lane all the way back down the hill to the Lake Washington bike trail and I-90. If don't have a copy of the King County bike map, pick up a copy at any King County library or print sections from it here. Total, it was about a 6-hour journey and it felt good not to add a single drop of carbon to the atmosphere!

Coal Creek Falls is one of the highlights of Cougar Mt. Park. I have often hiked from AA Peak and Red Town trail heads in loops that include these falls. The opening of the Sky Country trail head offers new opportunities to loop through the falls area as well as using a paved parking area as part of the trail head.

The loop I chose on this day went from Sky Country via the Old Man Trail to the Cave Hole Trail then via the By Pass Trail to Fred’s Railroad and from Fred’s RR to the Quarry Trail and then via the Coal Creek Falls Trail back the the Cave Holes Trail with the final leg of the trip on the Nike Horse Trail.

The trails were all in good shape with no mud holes but with recent horse activity and the normal deposits from said activity on the By Pass and Nike Horse trails in particular. I did not see the horse or horses but the signs of passing were fresh. Other than this there were no problems on the trail and the weather was superb! Sun and mild temperatures. I did not see people on the trails from Fred’s Railroad until I came to the falls were a young family was eating lunch.

Trip length about 3 miles with about 400 feet elevation gain.

Two of us and a big black fuzzy dog did the loop from the Red Town trailhead to Coal Creek Falls and back down through Quarry and Red Town meadow. The trails were in good shape, but there were many frozen muddy patches that were easy to walk on. When it warms up, there will be a lot of mud for a few days.

The falls were gorgeous, with roaring water and a lot of ice to catch the overcast light. It started snowing while we were at the falls, and continued for the rest of the loop (making the trail slippery). There did not seem to be enough snow to stick for more than a day. There were occasional ice patches across the entire trail that were very slick and caused all of us (including the dog) to go for a little slide!

Overall, great hike in good condition -- this is a perfect time of year for this area!
