Arapaho Lakes Trail

Trail intersections are unmarked and often unnoticed. This trail system is in dense subalpine forest, along creeks which lead to dozens of sparkling green lakes. Most of the lakes lie at or above treeline in delicate alpine tundra ecosystems - please be careful where you walk and camp.

A mile and a half up the Forest Lakes Trail #809 from where it leaves the South Boulder Creek Trail #900, the Arapaho Lakes Trail forks west. It follows the steep stream tributary for 1 mile to Arapaho Lakes.
