Camped on a Wednesday in June. Nobody else there. We did see several other campers near Chepeta Lake. Clean toilets, bear-proof trash, and an easy stroll down to the lake. Coming in on 117 from the west side was a little rough. We went out on the eastern route and it was smoother.
No water, no showers, no power.
We grabbed a dispersed site near the east Goldwater rim trailhead. Excellent pit toilets at the three trailheads. Bring plenty of water as there is none available. The views are unbelievable. Road in from Castle Dale is very smooth, graded and oiled, until the last two miles. The nice road continues to the west rim.
After two days of camping and biking here we took Buckhorn Draw Road down to I-70 and then Temple Mountain to Goblin Valley. Very scenic drive. National Park quality stuff.
