Meet at the Santa Cruz River Heritage Project near 1580 S Santa Cruz Lane. The river outfall can be viewed from the Chuck Huckleberry Loop, about a quarter mile south of W Starr Pass Blvd. Take local transit toward this area and walk the final stretch.
The route ends at the original El Charro Café at 311 N Court Ave in downtown Tucson. Walk to a nearby transit stop for your return to the main transit hub, and check the current connection on the day of travel.
