Overview

The outstanding lake and mountain views at Oh Ridge Campground make it a favorite spot for both families and anglers. It sits in the eastern Sierra Nevada Mountains in close proximity to the Ansel Adams Wilderness, Yosemite National Park and Mono Lake. The nearby town of June Lake offers the convenience of shopping and dining, while the surrounding land and lakes provide ample outdoor recreation opportunities.

Recreation

Oh Ridge campers have no problem staying busy and enjoying the outdoors. Within the facility, they can swim in the lake's clear waters, fish for rainbow and Alpers trout, go canoeing and boating or walk to the Oh Ridge viewpoint, after which the campground was named.

Numerous trails lie minutes away, an obvious draw for hikers, mountain bikers and off-road vehicle enthusiasts. The Fern Lake Trail leads into the scenic Ansel Adams Wilderness. Skiing is a major winter pastime in the area.

A scenic drive along the June Lake Loop results in expansive views of rugged mountain peaks and several lakes.

Facilities

This is a large facility with campsites organized among several loops named after area animals. The campground is equipped with drinking water and flush toilets, and sites have picnic tables, grills and bear-proof lockers for food storage.

The nearby resort offers showers and basic groceries and camping supplies.

Natural Features

Campsites are located in a mostly open area above the shoreline of beautiful June Lake. Save for some scattered pine and aspen trees, the campground has little shade. Nearly every point in the facility has a view of the surrounding 11,000-12,000' peaks. The campground's elevation is 7,600 feet.

Many species of wildlife call the mountains home, such as black bear, mountain lions, mule deer, pine marten, pika and numerous fish and birds.

Nearby Attractions

Mono Lake and its many activities are minutes away. Hikers can access the scenic Ansel Adams Wilderness via nearby trails, and Yosemite National Park is a great day trip.
