In 1980, the 225 miles (362 km) of the river within the wildlife refuge were designated "wild" and added to the National Wild and Scenic Rivers System. The designation means that most of the Nowitna is unpolluted, free-flowing, and generally inaccessible except by trail.
It is possible to run the Nowitna in many kinds of boats, including hard-shell, folding, or inflatable canoes and kayaks or inflatable rafts. Most of the river is slow-moving and meandering, rated Class I (easy) on the International Scale of River Difficulty. The exception occurs in Nowitna Canyon between Mastodon Creek and Big Mud River along the middle reaches of the Nowitna. This segment includes Class II (medium) rapids.
