Hike to Boulder Lakes

3.9 Miles Total - 859 ft gain - Out-and-Back Trail

Originally added by The Outbound Collective

The Boulder Lakes trail is a 3.9 mile hike to a pair of beautiful yet very different alpine lakes. The trail is perfect for families and all skill levels, and can be a day hike or a camping trip.

The upper lake (Little Boulder) is warm and perfect for swimming later in the summer. There are fairly large trout in this lake. The lower lake is bigger and has an abundance of campsites. If you want a bit more solitude, the trail continues further in two directions. Mosquitos can be a problem, so bring bug spray. 

Trailhead access can be difficult for low sitting vehicles or cars without 4WD. Dogs are allowed on this trail. The trail is best used from June through October due to snow accumulation at elevation.
