area map of Ansel Adams Wilderness

The Ansel Adams Wilderness is dotted with sparkling lakes, glacially sculpted gorges, and imposing peaks. Originally protected as wilderness by the 1964 Wilderness Act, it was first called the Minarets Wilderness. Renamed to honor Ansel Adams in 1984, it spreads over 230,258 acres, ranging in altitude from about 7,000 feet to 14,000 feet.

For thousands of years this area has been inhabited by people of the Miwok, Monache, Mono, Washo, and Shoshone tribes. Acorns, pinon pine nuts, and obsidian were gathered and traded along routes that crisscrossed this wilderness.

GETTING THERE

The Ansel Adams is located between Yosemite National Park and Mammoth Lakes. The John Muir Trail (and Pacific Crest Trail) passes through this wilderness, and it can be reached from both sides of the Sierra crest. Most people enter the wilderness from the east, starting in the Mammoth Lakes area (near Devils Postpile National Monument), or from the south near Lake Thomas Edison.

Shuttle Bus to Reds Meadow/Agnew Meadow

All visitors entering Reds Meadow Valley must pay a per-person user fee which supports the shuttle bus system.

WILDERNESS PERMITS

Permits are required year round for all overnight trips in the Ansel Adams Wilderness. Why?

A quota is in effect for all entry points into Ansel Adams Wilderness that applies to all overnight visitors from May 1 through November 1. Some trails have a separate quota for commercial use. Visitors using a commercial outfitter or guide must obtain their permit through the commercial operator.

Permits for backpacking in the Ansel Adams are available from the Sierra and Inyo National Forests, depending on where you plan to enter the Wilderness.

MAXIMUM GROUP SIZE

No more than 15 people and 25 head of stock are allowed per group on overnight trips. Why?

BEARS AND FOOD STORAGE

The Inyo and Sierra National Forests each have a forest order regarding food storage. In all wilderness areas of Inyo National Forest use of bear-resistant containers is strongly recommended. In eight specific areas it is mandatory to store food and refuse in a container designed to prevent access by bear. Where food storage containers are not mandatory the counter balance method of hanging food may be used, however where trees are not adequate for hanging food at least 15 feet above ground and 10 feet away from the tree trunk you must use a portable food storage container. No other methods of food storage are allowed.

Food storage containers are available for rent or sale at all the Inyo and Sierra National Forest visitor centers where wilderness permits are issued.
