Gates of the Arctic offers dozens of paddling rivers, with difficulty ranging from long, gentle floats to Class IV-V rapids. Rafting is the most common type of river trip in this area, because of the expense of transporting canoes and kayaks via aircraft.

Water levels tend to be safest in July and early August (which is also when the weather's likely to be at its finest), but rainy weather upstream can raise water levels (and danger) at any time. Aufeis, thick layers of ice created by the streams during winter overflows, usually have safely navigable channels melted into them by mid or late June, but they can be dangerous any time that water levels rise, as the water can carve narrow, high-walled channels or tunnels through the ice.

Listed below are the most rewarding and popular of the wild and scenic rivers that run through Gates of the Arctic National park, from the remote but relatively mellow Alatna to the wild Lower Kobuk Canyon. Stay aware of current river and weather conditions—it is usually possible to portage or line through the most difficult sections, but these rivers run through extremely remote wilderness.
