I dont know why it’s listed as closed for the season. The registration office is closed but campsites are reservable online and are available first come first serve w self pay as of May 16 2022. The closed for the season on Hipcamp appears to be in error. Mostly close together sites but the scenery is gorgeous. Right outside Saguaro Natl Park but also in a county park itself. Nice bathrooms, plentiful water fountains for filling. My site was supposed to have shade awning per county reservable website… it did not. Only a handful of sites actually have shade structure. There are no showers but there is a large handled faucet w hot running water behind the bathroom in C loop you can clean hair off with.
