Trail Overview

Starting at Glass Creek Road, this trail climbs 126 feet and drops 308 feet over just over a mile, leading toward the Obsidian Flat Group Campground. It forms part of the June to Mammoth loop and features heavy washboards, whoops, and ruts caused by frequent side-by-side use. There are a few small dispersed camping spots along the route. The trail offers scenic views of Glass Creek Dome, Dead Man Dome, and the Eastern Sierra mountains.
