However, The Alaska River Guide advises against trying it "unless you are an expert paddler, extremely self-reliant in Alaska wilderness camping, and ready for severe weather and self-rescue."[5] From a put-in at Surprise Lake, the river begins quietly, but downstream of the Aniakchak Crater wall it plunges through {{convert|15|mi|km}} of rocky rapids rated between Class II (medium) to IV (very difficult) on the International Scale of River Difficulty. Below the rapids, the rest of the river is rated Class I (easy).[5] In addition to rapids and low temperatures, hazards include winds up to {{convert|100|mph|km/h}} that can damage tents and other equipment and prevent airplanes from landing at the lake or on the bay.[5] Brown bears frequent the area.[5] Sharp rocks in the river may tear holes in inflatable boats.[5] These and other limits reduce the number of parties floating this river to only a few each year, mainly in July.[6] See also
