Colchuck Lake
Colchuck Lake
Colchuck Lake is widely celebrated as Washington's premier alpine lake hike, famous for its vivid, crystal-clear turquoise waters set against the sheer granite cliffs of Dragontail Peak. Reaching the lake requires a strenuous, roughly 8-to-9-mile round-trip trek starting from the Stuart Lake Trailhead with over 2,200 feet of elevation gain. Visitors often brave the freezing waters for a swim or relax along the rocky shores to take in the dramatic Cascade views.
Commenters consistently praise the scenery as breathtaking and otherworldly, with many stating the lake lives up to the hype and is worth the effort. However, feedback frequently warns that the hike is an intense, grueling uphill climb made tougher by heavy trail crowds, limited parking, and lengthy travel times from major cities.
- Arrive early around 4 a.m. to secure parking at the Stuart Lake Trailhead and avoid midday heat
- Prepare for a strenuous 8.7-mile round-trip hike with over 2,300 feet of elevation gain
- Pack bug spray, sturdy boots, and warm layers as temperatures dip near the water
- Verify permit, wilderness, and parking pass requirements before heading out
- Be cautious when swimming, as the alpine water remains freezing even in summer
