Go if
Hardcore dispersed-camping types who understand leave-no-trace and accept the legal gray zone might use this as a base in the Sierras, but go in with full water supply and no expectation of any infrastructure beyond a single vault toilet.

Anyone expecting a functioning campground will find nothing here. No water, no management, no legal standing to camp. This place is closed permanently and shouldn't be booked or planned around.
Availability, what to pack, similar spots — ask anything and get an instant answer.
Summer works best here. Daytime highs run 70–85°F with nights dropping to 35–50°F at this elevation. Trails and granite areas are accessible, and snowpack has melted off the access roads. Spring can be wet and muddy. Fall brings cooler temps and earlier darkness. Winter closes the area with snow, making access difficult or impossible without snowshoes or skis.
Site is permanently closed year‑round; summer camping is not officially allowed.
