Planning a soak in Arizona
- Check the official status link on each spring's page before you go. Closures for fire, snow, road work and water quality are common and we don't track them live.
- Many wild springs have no fee, no lifeguard and no facilities. "Not recorded" means we don't know, not that a spring is free or open.
- Follow posted rules on site, including any clothing policy. We only show a clothing policy where an official page states one.
