Glass Elevators Trail

Extreme granite slabs in the Eastern Sierra

Expert

Glass Elevators earned its name from the steep, polished granite slabs that rise like elevator shafts above Mammoth Lakes, offering some of the most technical rock crawling in the Eastern Sierra. This 12-mile loop climbs from Mammoth Creek through a series of increasingly difficult granite steps, passing pristine alpine lakes and offering jaw-dropping views of the Minarets. The “elevators” themselves — smooth granite faces with minimal traction — demand precise line choice and serious wheel placement skills.

Rated Expert, this trail requires a well-built rig with 35-inch tires, lockers, and comprehensive armor including rock sliders and skid plates. The granite is unforgiving and recovery points are limited on the steepest sections. July through September offers the best window when snow clears from the high country. No permits required, but expect crowds during peak summer weekends. The trail rewards skilled drivers with world-class alpine scenery and technical challenges that’ll push both driver and machine to their limits.
