I camped here twice this summer, once in late June and again in late July. Both times for hiking in Mt Rainier Nat Park. Great alternative to the parking lot conditions at Ohanakaposh just inside the park. Most of the sites are reservable, but a fair number are first come, first serve. The campsites along the river are the best, but fill up quickly near the weekend. Best to go early in the week if you don't have reservations. On my first trip I managed to get a riverside spot, not so lucky second time around. However, all the campsites are nice, large and well equipped. Camp hosts were very friendly and helpful.
