The walkin sites are amazing here! We had site number 21 and it had plenty of trees to hang our 4 hammocks. The west rim hike was nice and accessible from the campsite. It was in the 90s while we were there, but enjoyable under the shade of the trees. Rangers were super helpful with any questions we had. Bathrooms were ok at the walkin area, but not the best I've seen. The showers were hard to manage for my husband who is 6 ft. He said the shower head was at his chest and the stall was on the small side. Other than that, I have no complaints and would definitely go back.  There were no mosquitoes when we went in July. The crickets are super loud when it gets dark. Drove around the west and east campgrounds too.  The west have more privacy and tree coverage. the east is closer to the falls with less trees and more traffic through. The cabins looked super nice on the east side and the yurts were on the west side of the park. I would totally stay in the walkin sites again.  We also visited nearby Lula Lake while we were there. They have certain weekends when they are open to the public. Hiking trails and more waterfalls to see.
