Overview

Pyramid Creek is Desolation's steepest little adventure: 2 miles up granite slabs beside Horsetail Falls to Ropi Lake's swimming slabs. Short on miles, big on scenery — and rated Difficult for the scrambling.

  • Ropi Lake's deep pools and granite waterslides
  • Avalanche Lake above for a steeper extension
  • The quickest Desolation overnight from Highway 50
