This popular river trip takes paddlers from the Dennison Ferry Day Use Area to the Green River Ferry, a short distance from the visitor center area. Paddlers are treated to scenic flat waters with gravel bars, islands, and back channels to explore while spending the day on the river. Riverside caves are accessible by paddle craft at lower water levels and wildlife is abundant in this section of river.

The Green River is a dynamic river system with gravel bars, islands, and river channels that change each year. Use caution while recreating on the rivers and steer clear of downed trees and logjams.

About the Green River

The Green River is one of the most biodiverse rivers in the country. It is home to more than 150 fish species, more than 70 species of mussel including many threatened or endangered species. The river spans 25 miles (40.2 km) through the park and is dotted with sandbars, islands, and subsurface springs. The river averages 200 feet ( 61 m) wide and 10 feet (3 m) deep, though its depth may be much greater in places.

While considered a flat-water river, the current can still be very swift and prior paddling experience is recommended. Regardless of water level, always be alert to hazards such as submerged trees and rocks, drifting debris, and the park's ferry.
