Overview

Lake Aloha is Desolation Wilderness's crown jewel: a shallow, island-dotted lake spread across granite slabs at 8,116 feet beneath Pyramid Peak. The 5.8-mile approach from the Glen Alpine trailhead past Gilmore Lake is the classic route — short enough for strong hikers to day-hike, but best savored as an overnight among the polished slabs.

Highlights

  • Aloha's maze of granite islands and turquoise shallows beneath Pyramid Peak
  • Sunset alpenglow on the Crystal Range reflected across the lake
  • The Glen Alpine corridor's waterfalls and wildflower meadows
  • Easy cross-country wandering across open slabs
