The ground is hard-packed so rolling is fairly easy. The tables have extended tops. The vault toilets were closed due to coronavirus when we visited so I don’t know if they’re accessible.
We moved out of the valley and camped along the rim for a few days to get better internet reception. This is a checkerboard of BLM and private land so make sure that you’re camped on public land. Campground 40.35655, -116.99492
