Love this place. Discovered it by accident trying to avoid the loud motels off I70. Love that tent sites are free during the week. It was quiet but I wasn't alone. Sunset was amazing on the reservoir. But the wind comes up quite strong as it cools down so stake that tent down!
Plenty of spots. It's accessible by low clearance vehicle. Dumpster is the only amenity. A little hard to find private place to relieve yourself in the desert .. Hole in the rock road gives access to several slot canyons. We did Zebra Canyon.
Everything in this area is expensive. We were skeptical of tents at an RV park but they have a dedicated tent area that is right next to the river. The tent pad was big enough for one big and one small tent. The bathrooms are very clean and nice! We waded to the middle of the river and watched the sun set against a hill. Beautiful!
