This spot was very close to Capitol Reef. There was room still for a few more folks when we arrived on a weekday around 8pm.
It was extremely windy so we stayed in our car. Most other folks were in their cars or rigs as well. There were some spots amongst trees though that may have been a bit less windy. Big rig friendly. Dispersed camping - no amenities except a porter potty, which was clean! The landscape here was beautiful. It is right off the road, so there is some noise but not too much.
Favorite hike was Grand Wash to Cassidy Arch. We arrived early and had no parking problems at Grand Wash, and enjoyed extending the Cassidy Arch hike and not dealing as much with the crowded lot. Another one you want to hit early due to sun and heat. Gorgeous! Another tip - attend a ranger talk! We really enjoyed the geology one we went to, and it completely changed how we viewed the park from thereon out.
No reliable service here. To work during the day, we drove down to the visitor center in Torrey. Was able to work off of our mifi, Verizon.
