Overview
Katmai National Park and Preserve occupies roughly 4 million acres on the Alaska Peninsula, about 290 miles southwest of Anchorage. It was established as a national monument in 1918 primarily to protect the landscape altered by the 1912 eruption of Novarupta — one of the largest volcanic eruptions of the 20th century — and was redesignated a national park in 1980.
Today Katmai is best known for its extraordinary concentration of brown bears, which gather each summer to feed on sockeye salmon migrating up the Brooks River. The park protects one of the densest brown bear populations in the world, with estimates frequently exceeding 2,200 bears park-wide. Beyond the bears, the landscape encompasses active volcanoes, glacially carved valleys, coastal fjords, and hundreds of lakes and rivers.
The Valley of Ten Thousand Smokes — the ash-filled valley left by the 1912 eruption — remains a haunting and scientifically significant landscape. Though the fumaroles that gave the valley its name are no longer active, the ash flow deposits, some reaching 700 feet deep, are still visible and accessible via a daily bus tour from Brooks Camp.
Katmai is a genuinely remote destination. There are no roads connecting it to Alaska's highway system, and most visitors fly in to King Salmon and transfer by floatplane or boat to Brooks Camp. This remoteness means the park retains a wild character that few places in North America can match.
Before You Go
Permits and Reservations
Katmai does not require a general entrance permit, but camping at Brooks Camp requires advance reservations through Recreation.gov, and these fill extremely quickly — often within minutes of opening in January each year. Visitors who plan to day-trip to Brooks Camp from King Salmon or lodges elsewhere in the region also benefit from advance planning, as floatplane seating is limited.
A bear-viewing orientation is mandatory for all visitors entering the Brooks Camp area. This is conducted by park rangers and covers bear safety protocols, food storage rules, and how to behave on the trails and platforms. Attendance is required before you can access the viewing platforms or campground.
What to Pack
Weather on the Alaska Peninsula is unpredictable year-round. Even in July, temperatures can drop sharply and rain is common. Bring waterproof layers, rubber boots or waterproof hiking boots, and insect repellent — mosquitoes and gnats are significant in summer. Bear spray is widely recommended for any backcountry travel, though on the designated viewing platforms at Brooks Falls it is not necessary.
Visas
Katmai is located in the United States. For visa and entry requirements, visit TravelerPulse's Visas section and consult the U.S. Customs and Border Protection or U.S. Department of State official websites for current guidance relevant to your nationality.
Getting There
There are no roads into Katmai National Park. The primary gateway is King Salmon, a small community on the Alaska Peninsula served by scheduled commercial flights from Anchorage. Several Alaska-based carriers operate this route; verify current schedules and carriers directly, as service changes seasonally.
From King Salmon, visitors reach Brooks Camp by floatplane — typically a flight of around 20–30 minutes across Lake Naknek — or by boat along the Naknek River system, which takes considerably longer. Floatplane services are operated by multiple licensed air taxi operators based in King Salmon and Anchorage; the National Park Service lists authorized operators on its official site (nps.gov/katm), which is the best place to verify current operators.
Some visitors arrive directly from Anchorage by floatplane, bypassing King Salmon, or as part of guided fly-in bear-viewing day trips. These tend to be more expensive but can be practical for those with limited time. Verify schedules, prices, and availability directly with operators and well in advance of peak season.
Getting Around
Within Brooks Camp, the main visitor hub, everything is accessible on foot along a short system of dirt paths and boardwalks. The distance from the floatplane dock to Brooks Falls viewing platform is roughly one mile and takes about 20–30 minutes to walk.
The Valley of Ten Thousand Smokes is reached by a daily bus operated by Katmai Wilderness Lodge under a concessionaire agreement with the NPS. The roughly 23-mile road from Brooks Camp to the valley takes about 45 minutes each way; verify current schedules and prices on the official NPS site or with the lodge directly.
Backcountry travel in Katmai requires self-sufficiency. There are no maintained trails beyond the Brooks Camp area. Visitors exploring other parts of the park typically use chartered floatplanes or boats to access remote areas, then travel on foot with topographic maps and navigation skills. Bear-aware camping practices are essential throughout.
Where to Stay
Brooks Camp Campground
The only NPS-managed camping within easy reach of the bear-viewing platforms, the Brooks Camp campground is a small, electric-fence-enclosed facility that accommodates tent camping. Reservations open on Recreation.gov and sell out almost instantly each January for the following summer. A bear-proof food cache and other safety infrastructure are provided.
Brooks Lodge
The only lodge located within Brooks Camp itself is operated by a park concessionaire. It offers cabin-style accommodations, meals, and guided activities including bear-viewing and fishing. Reservations typically need to be made many months in advance. Verify current rates, availability, and booking directly with the operator.
King Salmon and Anchorage
Visitors unable to secure Brooks Camp accommodations often base themselves in King Salmon, which has a small number of hotels and lodges, or in Anchorage, doing day trips or overnight fly-in excursions. Options in King Salmon are limited; verify what is currently operating before planning your trip.
Remote Wilderness Lodges
Several private wilderness lodges operate elsewhere within or near the park boundaries, typically accessed by floatplane and offering all-inclusive packages oriented around fishing or bear viewing. These are generally premium-priced. The NPS website lists authorized concessioners.
Things to See & Do
Bear Viewing at Brooks Falls
The highlight for most visitors is watching brown bears catch sockeye salmon leaping up Brooks Falls. The peak of this activity typically occurs in July, during the main sockeye run, and again to a lesser degree in September when silver (coho) salmon run. Three elevated viewing platforms — the Falls Platform, the Riffles Platform, and the Lower River Platform — provide close, safe observation. Bears can number in the dozens at the falls during peak periods. Viewing is managed carefully by rangers; expect queues during the busiest days in July.
Valley of Ten Thousand Smokes
The daily bus excursion from Brooks Camp deposits visitors at a viewpoint above the ash-filled valley with interpretive signage. Hardier visitors can descend into the valley floor on a marked but unmaintained trail; the round trip is strenuous and requires proper gear and navigation ability. The scale of the 1912 eruption's impact is genuinely impressive.
Fishing
Katmai is a serious sport-fishing destination. The Brooks River, Naknek River, and dozens of remote lakes and streams support rainbow trout, salmon species, Arctic char, and grayling. A valid Alaska state fishing license and, for certain areas, a state park stamp are required. Verify current regulations with the Alaska Department of Fish and Game before fishing.
Backcountry Hiking and Kayaking
For experienced wilderness travelers, Katmai's coastline, lake systems, and volcanic terrain offer exceptional and uncrowded adventure. The park's remote coast is accessible by floatplane or boat; sea kayaking along the Shelikof Strait coastline is undertaken by experienced paddlers. The NPS recommends registering with rangers before any backcountry trip.
Photography
Katmai is considered one of the world's premier wildlife photography destinations. The bear-viewing platforms are designed to keep animals at a reasonable distance while allowing clear sightlines. Telephoto lenses are useful but not mandatory at the Falls Platform during peak activity.
Food & Drink
Food options within Katmai are extremely limited and largely tied to where you are staying. Brooks Lodge operates a dining room serving three meals a day for lodge guests; day visitors should verify in advance whether they can access meals without a lodge reservation.
The Brooks Camp camp store sells a limited range of packaged supplies and snacks. Anyone camping at Brooks Camp or spending multiple days in the park should plan their food supply carefully and bring adequate provisions from King Salmon or Anchorage. All food must be stored in bear-proof containers or the designated food cache; rangers enforce this strictly.
King Salmon has a small number of basic restaurants and a general store. Anchorage, as a full-sized city, offers the full range of dining options and is the best place to stock up on specialty camping food, dietary-specific items, or anything beyond basics before heading to the park.
Practical Information
Cell Service and Connectivity
Cell phone coverage within the park is essentially nonexistent. Brooks Lodge has Wi-Fi for guests, but connectivity is limited by satellite bandwidth. Travelers should download offline maps, the NPS Katmai app content, and any other needed information before departing King Salmon.
Emergency Services
Katmai is genuinely remote. Medical facilities are not available within the park. King Salmon has basic emergency services. Serious medical emergencies require evacuation, which in bad weather can be delayed. Rangers at Brooks Camp can coordinate emergency response. Carry a personal locator beacon (PLB) or satellite communicator for any backcountry travel.
Park Fees
Verify current entrance fees, camping fees, and any required reservation fees directly on the NPS website (nps.gov/katm) or Recreation.gov, as these are subject to change.
Accessibility
The main viewing platforms and trails at Brooks Camp are accessible to most visitors; the Falls Platform trail is a gentle boardwalk. The Valley of Ten Thousand Smokes descent and all backcountry areas involve rough, unmaintained terrain.
Bears and Wildlife Safety
Encountering bears outside of designated viewing areas is common. Never approach bears, always give them the right of way, travel in groups when possible, and carry bear spray in the backcountry. Store all food, trash, and scented items per NPS and ranger instructions at all times.
Safety
Brown bear encounters are the most discussed safety consideration at Katmai, but the park's infrastructure at Brooks Camp is designed to minimize risk. Stick to designated trails, obey all ranger instructions, and never leave food unattended. Bear spray is effective when used correctly and is recommended for any travel outside of the viewing platforms.
The remote and wilderness nature of most of the park means that self-reliance is essential. Weather can deteriorate rapidly, floatplane operations can be grounded for hours or days, and rescue response times are long. File a trip plan with rangers before any backcountry excursion and carry a satellite communication device.
Water in the backcountry should be treated before drinking. River crossings in Katmai can be hazardous due to cold temperatures, current, and unpredictable depth. Hypothermia is a real risk even in summer given cold water and changeable weather; dress in moisture-wicking and insulating layers and carry dry clothes in a waterproof bag.
