There are TWO CAMPGROUNDS in Echo Canyon State Park. There is the upper campground with FULL hookups for RVs and there is the lower campground meant more for tent camping. They appear about the same elevation, perhaps upper is higher. The lower campground is across Echo Dam Road from the boat launch entrance to the reservoir. The upper campground is at the end of a dirt road that runs along the west side of the reservoir. You can see the upper campground(aka RV campground) from Echo Dam Road- it has few tall trees and likely enough RVs to stand out. The lower campground is more hidden in the mountain with the trees. We stayed in the RV campground and used the electric hookups. There were water and sewer as well but we didn't use thus can't verify quality. Everything looked clean and well kept and the water had TWO spouts, which is very nice. Each spot had covered picnic tables and a fire ring. There was a small pile of firewood you could purchase on the honor system from the information stand at the entrance. The park, like all the Nevada State Parks with camping, is first come first serve. And you pay at the kiosk drop box. A ranger comes by and checks on the campers about once a day. It costs$15 per night without hookups and$25 with hookups. If you get the state park all access pass then camping is free, you just pay$10 for hookups if you use them. We ended up here because we went to Cathedral Gorge state park but it was full. This park had plenty of spaces and was just about 20 miles away. We chose Echo Canyon rather than staying in the Cathedral Gorge overflow area because we needed hookups due to the cold weather. Unlike other reviewers, our experience was bug-free! Also, visibility was far! We saw hundreds of deer across the meadows. The winds at night were very strong and loud but didn't do any damage. The morning sun was strong and warmed things up quickly. Overall, we thought this place was a great value because of the full hookups.
