Overview

Established in 1984, this portion of Inyo National Forest is a geological wonderland that was once part of the former Mono National Forest.  Along the edge of this ancient salt lake are ten-foot-tall tufa towers exposed after water levels dropped beginning in 1941 when river water was diverted to Los Angeles.  Tufa is limestone that precipitated when the alkaline lake water combined with calcium from underground springs.  Paoha Island in the center of Mono Lake is also a nesting area for snowy plovers and California gulls, giving its salty waters even more of a Pacific Ocean impression.  This entire region is volcanically active as evidenced by isolated hot springs, cinder cones that erupted as recently as 350 years ago, and the forest devastation caused by a 1989 release of carbon dioxide from Horseshoe Lake.  It is also rich in minerals, showcased by the mines at Bodie State Historic Park, a ghost town conserved in “arrested decay.”

Must-Do Activity

Open May through October, the Mono Basin National Forest Scenic Area Visitor Center is located on Highway 395, just east of Tioga Pass (the eastern entrance to Yosemite National Park).  It features interactive displays on geology and human history, the 20-minute film Of Ice and Fire: A Portrait of the Mono Basin, photo exhibits, and a bookstore.  Situated atop a hill on the lake’s western shore, it offers an overlook of Mono Lake, Paoha Island, and the Mono Craters.

Best Trail

On the lake’s south side is the fascinating Mono Lake Tufa State Natural Reserve, established in 1981.  A short trail leads from the unpaved parking area to the shoreline.  Just to the west, the 0.7-mile Plug Trail enters the cone of Panum Crater, a 650-year-old plugged dome volcano.

The fragile tufa formations are a great resting place for violet-green swallows and other migratory birds that come to feed on the lake’s abundant brine shrimp and alkali flies.

Peak Season

Summer

Fees

$3 per person at South Tufa Trail or America the Beautiful pass; $8 per person to enter Bodie State Historic Park

Road Conditions

There are well-graded dirt roads to Panum Crater, South Tufa, and Bodie State Historic Park.  However, the routes on the north and east sides of Mono Lake are loose sand that require a four-wheel-drive vehicle.

Camping

There are campgrounds at June Lake and along Highway 120 to Tioga Pass, but that road is closed in the winter.  Dispersed camping is allowed in Inyo National Forest, but be careful on the sandy roads around Mono Lake.
