Sheep Lake to Sourdough Gap — Sunday, Jul. 13, 2025

Mount Rainier Area > Chinook Pass - Hwy 410
Sheep Lake to Sourdough Gap by Ruck Walker

Enjoyed a gorgeous hike today; Sheep Lake to Sourdough Gap to Upper Crystal Lake.

Parking lot was almost full when I arrived at 6:15; I suspected it was a lot of overnight folks and this was confirmed as I had the trail mostly to myself until I arrived at Sheep Lake and saw a dozen tents all around the lake (well within the 100 foot restriction).

Most people were just waking up though so I continued in semi-solitude up to Sourdough Gap and, since I was feeling good, kept going into Mt Rainier NP. Note that the winds are strong up here; secure your hat and anything else you don’t want blown away!

I strongly urge any other hikers who have made it as far as the Gap to keep going. They’ll be rewarded with lush, verdant meadows, a glimpse or two of the resident marmots, and some real peace and quiet at Crystal Lake.

Traffic picked upon the way back; if crowded trails bother you this one is a doozy if you don’t hit the trail early.

Note: 2 of the 4 restrooms at the trailhead parking lot were out of order.
