June Lake Loop: Geology and Exploration

July 15, 2026

The air cools, and the granite peaks pull close as you turn off US 395 onto Highway 158. The June Lake Loop offers one of the most spectacular short drives in the Eastern Sierra.

This 16-mile scenic drive curves through a breathtaking canyon carved by ancient forces, offering a perfect half-day or full-day exploration itinerary.

At a Glance

Loop length: 16 miles | Drive time: 1-2 hours with stops | Lakes on the loop: June, Gull, Silver, Grant | Best for: Scenic driving, hiking, fall color

A Glacially Carved Landscape

During the Pleistocene Epoch, massive ice flows from the Rush Creek glacier ground their way along the Eastern Sierra. The ice split around Reversed Peak, slowly carving out a deep, horseshoe-shaped canyon. Today, this crescent-shaped valley holds a string of four glacially formed lakes: June, Gull, Silver, and Grant.

A Stop-by-Stop Guide

A June Lake Loop itinerary is best enjoyed at a relaxed pace. You should allow one to two hours just for the drive with time built in to pull over and photograph the scenery.

June Lake and Gull Lake: Starting from the southern entrance, you will find June Lake Beach and the village area. Most visitors can locate street parking in the Village, but be sure to park completely off the road and obey restrictions to avoid costly citations. Gull Lake Park is one of the easiest places to find ample parking and serves as a beautiful spot to take a picnic and watch the sunset over the Sierra Crest.
Balanced Rock: Near the local fire station, keep an eye out for a massive 18-foot-tall, 150-ton boulder resting precariously. This glacial erratic differs from the native rock and was carried to its present position by the ancient Rush Creek Glacier.
Silver Lake and Reversed Creek: Silver Lake offers incredible mountain views and vault restrooms. Nearby, you can observe Reversed Creek. This is an unusual waterway that flows westward back toward the mountains rather than away from them and is a result of the northern branch of the glacier carving a deeper canyon, creating a gradient that slopes back toward the Sierra Crest before turning away.
Grant Lake: As the largest body of water on the loop, Grant Lake is one of only two lakes in the wider area that allows motorized boating and watersports like wakeboarding and wakesurfing.

Finding the Famous Fall Colors

While spring and summer offer perfect weather for swimming, kayaking, and camping beneath alpine peaks, autumn completely transforms the landscape. The region is famous for its leaf-peeping season, as the loop explodes in vibrant color from mid-October to early November, one of several can't-miss fall destinations around Mammoth Lakes. The annual Leaves in the Loop event celebrates this spectacular display with local vendors, food, and community activities.

Hiking Options and Activities

If you are looking for active June Lake Loop things to do, some major trailheads provide entry into the Inyo National Forest and the surrounding wilderness. The area offers incredible hiking and horseback riding in the summer months. In the winter, you can enjoy skiing and snowboarding at June Mountain, or head out into the forest for snowshoeing, cross-country skiing, and ice fishing.

For those who prefer two wheels, the paved route is highly popular; check our June Lake Loop cycling page for details. When exploring the trails, please camp only in designated areas, pack out all trash, and keep dogs on a leash in developed recreation sites like campgrounds and picnic areas.

Combine with Mono Lake

The same volcanic forces that built the Mono-Inyo chain to the north have left their mark across this region too, in scattered pumice and ash deposits. You can easily expand your trip to see more of this geological story by driving north to the Mono Basin. Combining the loop with a visit to the striking tufa towers detailed in our Mono Lake geology blog creates a comprehensive and unforgettable Eastern Sierra road trip itinerary

Plan Your Alpine Stay

After a full day of driving the Horseshoe Canyon and exploring the marinas, you will want a comfortable place to relax. Mammoth Lakes sits just a short drive south, offering the perfect alpine basecamp for your regional adventures. Browse our lodging options to find a cozy cabin or a modern hotel room for your Eastern Sierra getaway.
