Trail Overview

The trail is a good day ride with great views and nice lookout points overlooking June Lake and Grant Lake. Most of the trail up to the Junction is trails through pine forest, 2nd half of the trail is mostly low shrubs. June Lake Junction store is about the halfway point with homemade milkshakes, snacks, and drinks. They also have a gas station if you're low on fuel.

Difficulty

Trail is nice and wide but not to sure if a 2 wheel drive will make the trip but any stock 4x4 should not have a problem.
