I Trail - Groomed Snowmobile Trail 12.9 mi

  • The I Trail, part of the Winter Grooming Snowmobile system for over-snow vehicle (OSV)/snowmobile use, is a popular connector trail between June Lake Junction and the A and D Trails. There is a general store and gas station at the junction of Highway 395 and Highway 158. Groomed and marked with orange diamonds, the trail crosses through the OSV tunnel under Hwy 395 north of June Lake Junction and heads out toward a small volcanic crater dubbed Devil's Punchbowl before straight-lining south to Deadman Summit. From here, the trail heads east and climbs toward the rim of the Long Valley Caldera, offering extensive views and multiple connections toward Bald Mountain Summit or south toward Lookout Mountain and Mammoth Lakes. The Winter Grooming Snowmobile System is groomed by the U.S. Forest Service with funding provided by the California Department of Parks and Recreation, using monies generated by registration fees and gasoline taxes. Click here for current snowmobile grooming info.
