The Idaho Oregon Snake River Water Trail Coalition is a 206 mile water trail along the Snake River in Southwest Idaho and Eastern Oregon for people to explore, respect and enjoy. A water trail is a water route that provides recreational and educational opportunities for motorized and non-motorized boaters and commercial opportunities for river communities. This trail begins at Three Island Crossing State Park, Idaho and ends at Farewell Bend State Park, Oregon.

Our mission:  The Idaho-Oregon Snake River Water Trail promotes river access and recreational opportunities that benefit communities, tourism and preservation of natural and cultural resources through a network of partnerships.
