Big Springs

Big Springs is a natural landmark in Island Park that consists of a large spring source producing millions of gallons of clear water daily. The system feeds directly into the Henry's Fork of Snake River and forms one of the region's most significant freshwater sources.

The spring served as a vital water source for Native peoples before European settlement and shaped human use of the region for generations. Later the site gained protection as a natural landmark to preserve its ecological significance.

The site contributes to environmental education through research programs focused on natural water systems and regional wildlife observation.

Access is provided through designated trails and viewing points where visitors can observe the spring from multiple angles. The grounds remain open for photography and wildlife watching, with fishing opportunities available in adjacent waterways.

The spring water maintains a constant temperature throughout the year while transporting tons of dissolved limestone daily. This unusually strong chemical composition makes the system a valuable research site for hydrogeologists.
