Kobuk Valley in April: what the park service says
April 1 moves the Northwest Arctic Heritage Center in Kotzebue to summer hours, 9 a.m. to 5 p.m. on weekdays, sometimes Saturdays too. Staff help plan camping and float trips and lend bear-resistant food containers on request. Kobuk Valley has no roads, campgrounds or lodging inside the park, so every visitor must be self-sufficient and bring their own camping gear for backcountry nights, the only way to stay overnight.
