A portion of all book sales from the links above benefits WTA and helps protect and maintain our trails. From the broad parking lot, the trail climbs moderately for 1 mile to the first views of the long hike. Here, at around 1600 feet, you'll find wonderful views from atop a rocky bluff on the side of the mountain. Hikers short on time and stamina could turn around here for a modest 2-mile outing. As you near the 1.8-mile mark, you'll sweep alongside a small brook, with grassy banks on which to rest. This is Snag Flat--the site of an old burn, as evidenced by the blackened scars on the trunks of many of the old Douglas-firs in the area. The trail then pushes on, never wavering from its steep ascent, until you finally crest the last slope and step out into the wildflower-filled meadow at the summit, or rather, the summit basin. The true summit of Si is atop the big rock "haystack" that towers over the edge of the meadow. The haystack does sport a scramble path to its summit, but the route is tricky, with incredible exposure (one slip and you'll plummet hundreds--thousands?--of feet). It's best not to attempt the Haystack, especially considering the added danger of other people kicking loose rock down, creating deadly missiles from above. Besides, the views atop the rock are no better than those you'll enjoy from the meadows at its base.

No snow until the 3rd mile up. A bit slippery and dropped about 20 degrees once at the top. Still a very nice hike. Wouldn't recommend for kids until some snow melts.

Hit Mt Si trail at 10:15 AM. All blowdowns cut out. Trail a bit wet/muddy near start but dry after that up until about 2 1/2 mile mark. Patchy snow there & steady snow shortly after 3 mile mark. Put on Yak Trax there. Took about 2 hours to summit. Did not get pelted w/ any snow from trees. Gorgeous day. Very windy up top, found little dry nook in rocks away from wind for lunch. Be careful hiking over the snow-covered rocks. Great views of Mt Rainier, Olympics, Seattle & Bellevue skylines, & Snoqualmie area peaks. Only passed a group of 6 women on way up. They had split up & 3 were at summit. I saw nobody else on summit. Saw more folks on the way down. Took me about 1 hr 20 min down. Now is a good time to do this hike to avoid crowds normally here in Spring/Summer. About 1 to 2 feet of snow on summit.

Parking lot was fine -- usual potholes are there but snow from last week was all melted.
Fantastic day for a hike. Blowdowns from last week had been cleared (thanks!) Snow on trail from about the 1.5 mile mark. It had snowed recently, but snow on the trail was packed down. Had thought I might need gaiters, but did not. Traction devices (microspikes) and poles were very helpful.

Trailhead: The toughest part of the trip was navigating the parking lot: lots of snow and slush. Trail conditions: the trail was slightly icy in places; two trees were over the trail down low. Snow conditions at the top: about 4" to 5" of fresh snow over a crusty base. Equipment: no need for gaiters; traction devices were helpful (we used "microspikes" from about 2300' on); no floatation devices were needed. Weather: considerable wind (from the east or southeast) up high (I'd guess about 30 mph - not enough that you had to lean into it); snow flurries during the day. People: very few people were on the trail; though as we were ascending, we bumped into Bob H. while he was descending. Times: car to first talus field (slightly below Snoqualmie Valley Viewpoint) - 2:45 hr; car to car - 4:45 hr (one party member had no interest in progressing beyond the talus field) Companion: Amy.

Hike #3 of my one hike a week.
Road clear all the way to parking lot. Lot and trail full of snow that turns to very mucky slush in the afternoon. Get there early to avoid too much slush. No views due to fog. Plenty of hikers, a couple blowdowns, and traction devices not needed but recommended. Warm clothes and especially gloves recommended for an extended stay at the top. 3 Hour hike time (2.7 mph average); Kicked my butt! |
