Rattlesnake Mountain

If you've hiked to Rattlesnake Ledges and beyond from Rattlesnake Lake, this is a delightful alternative. Thanks to the handiwork of our colleagues in the trail community, you can now reach Rattlesnake Mountain from the west, starting from a new trailhead at Snoqualmie Point.

Expect more solitude on this approach, and enjoy the fantastic views out over the Snoqualmie Valley, Mount Si, Mount Teneriffe, North Bend and more. You can choose to hike to one of the pleasant viewpoints along the way, to Rattlesnake Mountain, or as a traverse all the way to Rattlesnake Lake (11 miles). The views are some of the best in the Cascade foothills and the trail can be hiked year-round, though it can be snowy in winter.

The trail was officially dedicated in June 2007, though people have been hiking along a mix of trail and logging roads for years. Now the trail winds its way through mostly second-growth forest, crossing a few logging roads and requiring just a few stints on old roads.

The trail follows I-90 fairly closely, but there are times you don't remember that it is there. Still, the reality of being in a managed forest does intrude - you do see and walk through clearcuts. Fortunately, the forest canopy does get more mature as you go, and there is a delightful progression of ecosystems along the way.

The first nice viewpoint is Stan's Overlook, about 2.5 miles in (elev. 2100'). From there you can see Mt. Si and the Snoqualmie Valley. Next up, and a fine turn-around for those not traveling end-to-end, is Grand Prospect at about 4.9 miles. This precipice is due south of the town of North Bend. At six miles and 3500 feet is the high point of East Peak - great views abound from here! Then it is downhill to the Ledges (8 miles) and ending at Rattlesnake Lake (that is, if you've cached a car here).

This trail system is the result of thousands of hours of hard work by trail crews from Washington Conservation Corps, EarthCorps, and Washington Trails Association (WTA's handiwork was up to the Ledges from Rattlesnake Lake), all jointly managed by the Mountains-to-Sound-Greenway and DNR. If you see a crew, please take the time to thank them!

I didn't have time for a long drive so I settled on an old favorite. I had not been up to the East Peak and back down in a decade. I have done a number of one way trips from end to end on the Rattlesnake Mountain Trail but not up and down from Rattlesnake Lake. I was surprised to find a number of empty spaces in the paved hikers lot at 9:15 am. There was a little snow at the trailhead so I took my snowshoes. The lake itself is snow free and almost water free too. I have seen it low but not this low. The trail is very gentle as it gains 1150" over two miles to the lower ledge.

I passed several groups already coming down and a few heading up. The lower trail was snow free though there was a little at the ledge. I took a short break at the lower ledge. Low clouds all around but the sky was mostly blue. I was soon on my way higher. I took another break at the upper ledge. My camera batteries did not like the cold and refused to extend the lens. I warmed them in my hand and they worked for the rest of the day. Lots of color photos that look like black and white. It will be that way for many months.

Above the upper ledge the newest trail reroute began. Instead of the old route straight up the ridge it now goes far to the left and switchbacks to the right. This is longer but much gentler. I caught up with two hikers with whom I played leap frog the rest of the way to the summit. One of them was always ahead and I was second or third in line. Snow began soon after the upper ledge and slowly deepened. There were a few footprints before ours. It snowed the day before covering any older prints.

I recognized the old quarry and a few minutes later we reached the road. Snow was about 8 inches deep on the road. It was a little thinner back on trail though the trail was built very wide through here and there are not many trees overhead to catch snow. Coming out of the trees just below the summit ridge the snow was now a foot deep. If I had any distance to go I would have put on the snowshoes. As it was I carried them up and down. The rest of the group of the two hikers I was near coming up were having lunch where the road reaches the ridge. I continued over to the tower.

A few postholes here were more than knee deep. The snow was unconsolidated so ever step was a posthole. I had lunch and headed down. The other group was still enjoying their break. They were not enjoying any views because there were none. Clouds were all around us on the summit. The trip down was much faster. About 2 1/2 hours up and 1 3/4 down. With all the changes to the trail in the decade since my last time on this route it's hard to figure the distance. The first mile is now two and the switchbacks above the upper ledge must add about 1/4 to 1/2 mile. I'm guessing it is a little more than 9 miles round trip now.

Coming down from the lower ledge I decided to count the hikers I passed. The two miles took about 40 minutes in which time I went by 84 people. This is November and it was below freezing most of the day so I'm sure that was well below average for this trail. Solitude is not a reason to be on this trail. It turned out to be a fun hike. Heavily flocked trees up high and steps to follow in the snow. Not much of a crowd above the lower ledge. A little sunshine to brighten up the day. Not bad for a close in trip.

As usual, the weather was the first topic of discussion this morning and then hunter avoidance was brought up. Rattlesnake Mt seemed like a logical choice so we headed to the west trailhead off exit 27 on I-90. The trail was in very good condition but the views were minimal. Sometimes the clouds would lift a little while we stopped at the multiple rest/view spots west of the east peak. As we got closer to the east peak, we started thinking about some way to complete the traverse to Rattlesnake Lake even though we had no car at that point. BINGO!! At the East Peak, we ran into some friends that were doing a westward one way traverse and we scored a set of car keys. The clouds continued to rise as we descended and there were even some views of Chester Morse Lake. Near the east end of the trail, there were the usual hordes of people, all enjoying the trail as we were.

Another hike for H-a-T. We parked at the gate at 6:15am, not realizing the gates didn't open until 7a. and hiked to Grand Prospect. Very well maintained trail. We were pleasantly surprised by the nice benches at the viewpoint, although the fog was too thick to see any views. Lots of yummy thimbleberries!

Rattlesnake ridge/mountain is 99% snow free now! Only one other car in the parking lot at exit 27 when I arrived at 7:30. Don't come any earlier, the parking area and bathrooms won't be open. The trail is in great shape, not even any significant blowdowns to talk about. There are only 2 places with snow still on the trail: 1) near Windy's Lookout just west of the main towers and 2) about a half mile east of the towers. It was very easy crossing and will probably be melted in a few more weeks of nice weather. I stopped at Rattlesnake Ledge and had a snack before returning. Decided not to go all the way down to the lake and avoid the Sunday crowds. 17 mile round trip. No views today.

We did the traverse from Snoqualmie Point to the Lake. 11 miles / 6 hours including lunch and photo breaks. There was very little shade on the Snoqualmie Point side so be sure to bring sunscreen. There was a lot of snow for a couple of miles near the top, but it wasn't too bad with poles. Most of it was compacted. It was extremely crowded on the ledge side that day because of Memorial Day weekend. The Snoqualmie Point side was pretty peaceful.
