We carefully monitor canyon conditions for passenger safety. When the water flow is greater than 9 inches deep over any of the low water crossings, the Sabino Canyon Crawler will operate its High Water Tour traveling to Stop 2 and then return with stops at Sabino Canyon Overlook and the dam. The High Water Tour is also approximately one hour with special narrative program. The canyon will reopen the normal Sabino Canyon Crawler tour when it is safe to do so. Bear Canyon service is also suspended during high runoff events.
