River Description

Paddling this reach is currently PROHIBITED by the National Park Service.  For more information please refer to the Yellowstone Project Page link.

The Wild and Scenic Lewis River flows from Lewis Lake through several small rapids before cascading over the Class V+ Lewis River Falls.  Paddlers would put in below the Falls at the main road crossing.  Following the falls the run appears to consist of moderate and good whitewater with at least a couple standout big Class V series of rapids.  As you would likely expect the scenery, water quality, and paddling experience are all very high quality.  While the road roughly parallels the river, it is seldom in view because the river is set in an ash and rock canyon far below.  The take out would be near the South Entrance to the Park.  Paddling would be a great way to explore and experience the Lewis River - if it were legal.
