Many kinds of watercraft can be used for boating on the Nuyakuk. The Alaska River Guide describes the stream as "an excellent river for families or novices, with experience in portaging...especially those who enjoy fishing."[4] The segments of the Nuyakuk that require portages occur along the upper 7 miles (11 km) of the stream below Tikchik Lake. Two sections of Class II (medium) water on the International Scale of River Difficulty are along this part of the river. Below this, the river plunges over a 0.5-mile (0.8 km) series of ledges in a sequence rated Class IV (very difficult) to V (extremely difficult). Beyond these rapids and ledges, the river is Class I (easy) all the way to the mouth.[4]
