How to get there
Regularly scheduled flights connect Anchorage with King Salmon, the park’s administrative headquarters. Most visitors experiencing the wilderness arrive at Brooks Camp by floatplane; bus transport from Brooks Camp reaches the Valley of Ten Thousand Smokes. Direct wilderness access can be arranged by chartered air taxi from Anchorage, King Salmon, Iliamna, Kodiak, Soldotna, Port Alsworth, and nearby communities. Boats can reach the Katmai coast from Pacific coastal communities and locations in the Naknek River drainage from Naknek and King Salmon. Confirm the intended landing or boat-access location and applicable rules with the park before arranging transport.
- Brooks Camp
The main arrival point for many wilderness visitors, generally reached by floatplane. It provides access to Naknek Lake and bus transport to the Valley of Ten Thousand Smokes. Campground reservations and developed-area camping restrictions apply.
- King Salmon
A transport staging point and the park’s administrative headquarters, served by scheduled flights from Anchorage. Charter air taxis provide wilderness access, and boats can reach locations along the Naknek River drainage.
- Naknek
A boat-access staging community for wilderness locations along the Naknek River drainage. Arrange the destination and transport details before departure.

A volcanic wilderness on the Alaska Peninsula
Katmai Wilderness lies within Katmai National Park and Preserve on the Alaska Peninsula, approximately 290 air miles southwest of Anchorage. Its terrain spans active volcanoes, glaciated peaks, large lakes and rivers, and rugged coastline. The Valley of Ten Thousand Smokes is a defining feature: a forty-square-mile ash flow, 100 to 700 feet deep, deposited by Novarupta during the June 1912 eruption. Katmai, Trident, Mageik, Martin, and Fourpeaked are also active volcanoes within the wilderness. A trip here can focus on volcanic terrain, lake country, or the coast, but those settings require different transport arrangements rather than a single standard itinerary. Katmai also holds a long human history, from Native Alaskan homes and villages to places associated with later trappers, miners, and clammers. Treat cultural remains as part of the landscape to leave undisturbed.
Lakes, salmon, and bear country
Brown bears occupy Katmai’s coastal and lake regions, supported in part by the fish moving through its waters. Brooks, Coville, and Grosvenor lakes, along with the Iliuk Arm of Naknek Lake, are major features of the wilderness. The Savonoski, Katmai, Kamishak, Swikshak, and Big rivers provide habitat for salmon, trout, and other fish. Wildlife watching therefore calls for more than choosing a viewpoint: give animals room, keep food secure, and seek current bear-safety guidance before setting out. Lake edges and marshes support nesting swans, ducks, loons, grebes, and arctic terns, while coastal waters and offshore islands hold sea lions, sea otters, and seals. Moose, caribou, wolves, and wolverines also inhabit Katmai. Choose a trip around the habitat and terrain rather than expecting particular sightings, and allow wildlife movements to shape the day.
Brooks Camp and wilderness camping
Brooks Camp is a common gateway, with wildlife viewing and access to Naknek Lake, but its campground rules differ from those for the backcountry. Camping at Brooks Camp is allowed only in the designated campground. Reservations accommodate groups of up to six people, with a campground quota of 60 people per day; July is usually full. No permits are required for backcountry camping. However, backcountry camping is prohibited year-round within the Brooks Camp Developed Area, defined as the area within 1.5 miles of Brooks Falls, and in the core Hallo Bay meadows from April 1 through October 31. Do not assume an unreserved arrival can be accommodated near camp. Brooks Camp Campground’s peak season is June 1 through September 17. During the May and late-September-to-October shoulder periods, services are minimal: water, firewood, a live electric fence, and ranger or maintenance services may not be available. Plan without mobile service.

Route options

Use Brooks Camp as the gateway and bus transport to reach the valley. This option focuses on the extensive ash-flow landscape created by Novarupta’s 1912 eruption; confirm onward walking plans and conditions with the park.
- Naknek River drainage by boat
Arrange boat access from Naknek or King Salmon to wilderness locations along the drainage. This is an access-based itinerary rather than a defined hiking route; settle the landing, pickup, and camping plan in advance.
- Katmai coast by boat
Reach the rugged coast by boat from Pacific coastal towns or villages. Plan around coastal wildlife and brown bear habitat. Backcountry camping in the core Hallo Bay meadows is prohibited from April 1 through October 31.
