Site details

A spring-fed cove on the Snake River in the Hagerman Valley's Thousand Springs area, famous for vivid turquoise water created by geothermally warmed groundwater welling up through volcanic rock. The site is reachable only by water (kayak, canoe or paddleboard) on a roughly 1.5-mile downstream paddle from Banbury Hot Springs. The pool is shallow and exceptionally clear, popular for snorkeling and easy diving, with spring water holding around 58F year round.
