Quiet, tiny, love!
Been here many times with my son and my horses over the years. Still quiet and not over ran. Close to fishing streams, high mountain lakes, hiking trails, off roading and don't forget that trip into Bridgeport and Bodie.
Obsidian took a beating two cleaned up and they are still fixing some things. I would vonsider Obsidian more of a primitive campground, not dispersed but minimal.
Outhouse is clean, bring your own water, can get 5G/LTE here.
Tables, campfire rings, park at your site, tent, small camp trailer. At the end of the campground there is a bigger spot for groups.
Horsetrailer parking/camping across from campground in a turn around spot.
$12/Night for single unit $6/Night for extra vehicle
