Mammoth Lakes Backcountry Loop

This high-altitude loop climbs through the volcanic landscape above Mammoth Lakes, accessing remote corners of the Inyo National Forest that most visitors never see. The route connects old mining roads with forest service tracks, passing abandoned cabins from the 1880s gold rush, natural hot springs, and pristine alpine lakes nestled below 13,000-foot peaks. Key waypoints include the Sherwin Creek drainage, Valentine Lake access, and connections to the extensive Mammoth Mountain area trail system.

Most sections require 4WD with good ground clearance for rocky climbs and stream crossings, though a few technical spots favor experienced drivers with recovery gear. Snow closes high sections from November through June — plan summer visits with extra layers for sudden weather changes. The loop offers excellent dispersed camping with stunning Sierra Nevada views. You’ll experience the Eastern Sierra’s dramatic transition from sagebrush desert to alpine wilderness, with fishing, hiking, and photography opportunities that rival any mountain destination in California.
