All around Mono Lake is USFS and BLM land that is open for dispersed camping, as long as you stay above the 1941 water line (you will see signs marking this line, which is fairly close to the lake). Note there are multiple pull out areas and forest service roads to stay in along Hwy 120 east just be mindful that the entire area is sand, as some vehicles may get stuck.

The road into these spots is quite sandy and narrow in some places, but we did fine in our 26' Class C. There is a very large previously burned area with charred remains of plants and trees but it made for some interesting eerie photos. Very quiet place with amazing views and stunning night sky. There are no amenities so bring water and pack in and pack out all trash. Nearby are various hikes and other roads to the range of craters in the area and the tufas along Mono Lake.

We stayed there on a Monday night and did not see anybody else around, other than a truck that drove past our camp spot in the night.  Very quiet night.

Good cell reception from AT&T, Verizon and T-Mobile.

Note that Google Maps said that Hwy 120 is closed Oct through May and would not direct us to this area via that road, but the road was open in April 2021, probably due to the mild winter.  Check Hwy 120 conditions for yourself because without it you miss out on so much beautiful area to explore.
