The Nenana River pulses with a restless energy, carving its way through the rugged Alaska Range as it skirts the boundary of Denali National Park. Launching from a quiet put-in near McKinley Chalets, the 11-mile float invites adventurers to glide through water that dares you forward, its currents sweeping over smooth granite and rumbling through gentle whitewater that tests your paddle skills without overwhelming. The river acts as a natural divide—on one side, the sprawling wilderness of Denali, unspoiled and distant; on the other, views of towering peaks like Mount Fellows and Sugarloaf Mountain stand guard, silent and imposing.
