Mammoth Lakes

Mammoth Lakes is a picturesque alpine resort town nestled in the eastern Sierra Nevada Mountains within Inyo National Forest, Mono County, California. Surrounded by approximately 1.9 million acres of federally protected wilderness, it sits at a high elevation (around 8,000 feet in town, with nearby areas reaching much higher) and offers stunning natural beauty year-round.

The area features crystal-clear glacial lakes (such as those in the Mammoth Lakes Basin: Twin Lakes, Lake Mary, Lake George, Mamie Lake, and Horseshoe Lake), dense pine forests, dramatic granite peaks, meadows, and volcanic landscapes. It borders wilderness areas like the Ansel Adams and John Muir Wildernesses and provides access to attractions such as Devils Postpile National Monument and the Pacific Crest Trail.

Mammoth Lakes is a four-season destination, famous for world-class skiing in winter and exceptional outdoor recreation in summer and fall. Its proximity to stunning scenery, combined with convenient access via U.S. Highway 395 and local amenities, makes it a premier hub for nature lovers.

Fishing in Mammoth Lakes

Mammoth Lakes is renowned as one of the top fishing destinations in the western United States, with abundant opportunities for trout fishing in alpine lakes, rivers, streams, and creeks. Anglers target species including rainbow, brown, brook, and golden trout (catching one of each is known locally as a “Sierra Slam”).

Popular spots include the Mammoth Lakes Basin (road-accessible lakes like Lake Mary and Convict Lake), Hot Creek (a famous fly-fishing area), and nearby June Lake Loop. Fishing is possible from shore, boat, dock, or by wading, with both stocked and wild fisheries. The general fishing season in Mono County typically runs from the last Saturday in April to November 15, though some catch-and-release waters stay open year-round. Always check current California Department of Fish and Wildlife regulations, limits, and permits.

The area’s high-elevation, cold, clear waters provide a challenging yet rewarding experience, often with beautiful mountain backdrops.

The Mammoth Lakes area boasts over 300 miles of trails managed jointly by the Town of Mammoth Lakes and Inyo National Forest, ranging from easy lakeside strolls to strenuous high-country treks.
