In season (roughly June 1–September 17), the NPS operates a Visitor Center, ranger station, campground, and daily ranger programs. Brooks Lodge (separate concessioner) provides lodging and meals through about September 17; it’s very competitive to book.
Campers get real infrastructure: an electrified bear‑resistant fence around the campground; three covered cooking shelters with picnic tables and nearby fire rings; separate food and gear caches; fuel lockers; potable water (typically June 1–Sept 17); and two vault toilets. There are no assigned sites (60‑person capacity). Showers and charging are by the lodge (expect limited outlets and bring a battery pack). Don’t count on cell or internet.
A small trading post sells limited supplies (including camp fuel when available) and basic snacks, plus rents items like kayaks, canoes, and fishing gear. Stock varies, hours are limited, and fuel availability isn’t guaranteed—bring what you truly need.
