When I checked the website to make a reservation, it appeared all of the sites except the yurts were booked. In a panic, I booked a yurt for two nights. We were surprised that upon arrival, many sites were empty. The ranger at the visitor center explained that the website was very confusing; the only reservable “sites” are the yurts. Since others are first-come, first available, check out all the sites carefully as not all are level and some barely have enough room to park a car. Some back up on the river, which is nice. Our yurt was nice and clean. There was a mattress cover on the bed, which was not expected. A table and three chairs were a nice touch. You are expected to clean the yurt before departing. All sites/yurts have easy access to several trails (walking) but you do need to drive to see the Sink/Rise, which is very interesting. Pit toilets and no hookups. Water pumps are available.
