Trail Overview

This fine-dirt trail climbs up and over the hillside with minor 2–3 inch ruts. Expect occasional overgrown vegetation that may scrape the undercarriage, 12–18 inch whoops, and low-hanging branches providing approximately 8 feet of overhead clearance. Several sections also require carefully weaving between tight trees. Camping is plentiful throughout, with numerous level, shaded sites surrounded by scenic forest. Around 2.1 miles, several large campsites can accommodate up to 20 vehicles each, offering full shade and expansive views overlooking the valley and Sandy Flat.

Difficulty

This trail is rated Level 2 because of the 12–18 inch whoops, tight trees, low-hanging branches, and minor overgrowth. Around 8 inches of ground clearance is helpful but not required, and the fine dirt can become more difficult when wet.

History

Inyo National Forest was established in 1907 and today protects a vast section of the Eastern Sierra surrounding Mammoth Lakes. The area has a long history of Native American use, mining, ranching, and recreation, while its dramatic landscape was shaped by volcanic activity, glaciers, and the uplift of the Sierra Nevada.
