The Inyo Craters Loop is an old school Mammoth ride. It was one of the earliest USFS signed bike routes. Other than the Inyo Craters Singletrack
(which we include with our version of the loop), the terrain is pretty much jeep roads. There is moderate climbing, with some sweet views and a good tour of the area. This is a relaxing ride thats definitely worth doing for some peaceful exercise.
**NOTE FOR WINTER / FAT BIKE RIDING This route is usually packed by snowmobiles and trucks before grooming starts for the season. Other than the singletrack section (which sees no winter use) the rest is usually fun on a fat bike with low tire pressure. Remember, once grooming starts, all groomed trails are OFF LIMITS to bikes. Click here for the grooming report to see if its currently legal to ride.

From Mammoth, drive up Highway 203 towards Main Lodge of Mammoth Mountain Ski Area. Make a right on Mammoth Scenic Loop. At 2.75 miles, turn left on 3S30 at the Inyo Craters sign. Go 0.3 miles. The road will split and theres a dirt parking area on the right. The ride starts here. The singletrack is to the right, and theres a small sign with no trail name (see photo).
Soon after finishing the singletrack section, you ride out of the forest and a huge pumice flat opens up in front of you. 360-degree wicked views await, including San Joaquin Ridge and White Wing Mountain. Next you enter a Jeffrey Pine Forest and cross Deadman Creek before paralleling the creek and curving around and starting back towards the craters. After a peaceful ride through the forest, you arrive at the main parking lot. Lucky for you, you get to ride the singletrack back the way you came. Nice!
