Fossil Creek permits on sale: What you need to know Deborah Lee Soltesz/Coconino National Forest The Sally May site on Fossil Creek Wild and Scenic River offers some of the best swimming along the entire creek. There are two parking areas on either side of the bridge, which crosses Sally May Wash, on FR 502 (the Childs Power Road). Each lot has a path leading to separate pools along the creek. On the east (upstream) side of the bridge, the path leads to a large, deep pool at the base of a steep water feature. Rock shelves and cliff walls provide a lot of great spots for sunbathing and enjoying the canyon views. A smooth rock outcrop makes a great jumping-in spot. A small sandy beach at the far end of the pool offers shallow water entry and a good spot for smaller children to play.
