Katmai is, in many ways, a wilderness park. Accessible facilities are concentrated at Brooks Camp. Elsewhere, accessible facilities and trails do not exist.

Most of the public buildings in Brooks Camp, including the restroom facilities, are ADA accessible, but assistance may be necessary to navigate the trails and access the wildlife viewing platforms. Entering and existing float planes can be challenging for people with limited mobility.

The bear viewing platforms are accessed along elevated walkways with ramps. All bear viewing platforms are accessible. These platforms are located .25 mile (.4 km) to 1.2 miles (1.9 km) from the Brooks Camp Visitor Center. The trails to the Brooks Falls and Riffles platforms are accessible. However, the narrow paths at Brooks Camp are rough and can become very muddy. Wheelchairs and personal services are not available for assisting visitors around the Brooks Camp area.

Close encounters with brown bears are possible anywhere in Katmai, especially at Brooks Camp. Bears frequently use the same trails and roads as people. Please be aware that you may need to move off of the trail and enter the woods to allow bears to pass.

Quick Overview

This is the audio-only described version of the park’s brochure. Side one contains text, contemporary and historic photos and an illustration, which highlight the natural and cultural history of the park. Side two contains a large map of the park, text, and photos to help plan your visit.

Introduction to the Park

The top half of side one provides an introduction to the history of the park and its vastness. A photograph of an expansive park landscape is at the top. Five smaller photos, mostly of bears, is across the bottom of the large photo. Text is underneath the photographs. The text and photo descriptions are presented under their own sections.

Introductory Text

Katmai was declared a national monument in 1918 to preserve the living laboratory of its cataclysmic 1912 volcanic eruption, particularly the Valley of Ten Thousand Smokes. Since then most surface geothermal features have cooled, but protecting brown bears has become an equally compelling charge. To protect these magnificent animals and the varied habitat, the boundaries were extended over the years, and in 1980 the area was designated a national park and preserve. Katmai looms so vast that the bulk of it must elude all but a few persistent visitors. To boat its enormous lakes and island-studded bays, to float rushing waterways, to hike wind-whipped passes of imposing mountains, or to explore its Shelikof Strait coastline requires great effort and careful logistical planning.This unseen Katmai lies beyond our usual experiences of fishing from Brooks Camp, walking up to Brooks Falls, and riding the bus out to the Valley of Ten Thousand Smokes. We come to Katmai to sample but an edge of its enormous raw natural force, a sampling itself constituting a rare and endangered opportunity.Katmai’s awesome natural powers confront us not only as volcanics but as brown bears. In summer, North America’s largest land predators gather at streams to feast on salmon runs, build weight from this wealth of protein and fat, and prepare for the coming long winter. Alaska’s brown bears and grizzlies are now considered one species. Generally, grizzlies are those living 100 miles or more inland. Browns are bigger than grizzlies thanks to their rich fish diet. The Kodiak brown bear is a subspecies geographically isolated on Kodiak Island in the Gulf of Alaska. Mature male bears in Katmai may weigh up to 900 pounds.Mating occurs from May to mid-July, with the cubs born in dens in mid-winter. Up to four cubs may be born, at a mere one pound each. Cubs stay with the mother for two years, during which she does not reproduce. The interval between litters is usually three years. Brown bears dig a new den each year, enter it in November, and emerge in April. About half of their lifetimes is spent in dens. Because each bear is an individual, how that bear will act in given situations cannot be predicted with any precision. These great and awe-inspiring bears symbolize the wildness of today’s Katmai.


A photo caption and its description are presented first. Associated text follows.Photo caption: Salmon crowd up small creeks to spawn in the waters where they hatched. Photo description: Dozens of sockeye salmon crowd the edge of a stream. The water is so shallow that their bright red, humped backs break the surface. A few fish have their heads above water, showing the hooked jaws that males develop during spawning. Photo credit: NPSText: Another predictable eruption takes place each year as salmon burst from the northern Pacific Ocean into park waters. Sockeye (red) salmon return from the ocean—where they have just spent two or three years—to the headwater gravel beds of their birth. Their size averages five to seven pounds, varying proportionally to how long they have spent feeding at sea.The salmon run begins in late June. By the end of July a million fish may have moved from Bristol Bay into the Naknek system of lakes and rivers. Salmon stop feeding when they enter fresh water, and body changes lead to their distinctive red color, humped back, and the elongated jaw they develop when they spawn—in August, September, and October. Stream bottoms must have the correct texture of loose gravel for eggs to develop. The stream must flow freely through winter to aerate the eggs. By spring the young fish, called fry, emerge from the gravels and move into the larger lakes, to live there two years. Then the salmon migrate to sea, returning in two or three years to repeat the cycle. Salmon are food for bears, bald eagles, rainbow trout, and—directly or indirectly—for other creatures who forage along these streams. They also have been important to Katmai people for several thousand years, and commercial fishing—outside the park—still anchors the local economies today.Lake edges and marshes are nesting sites for tundra swans, ducks, loons, grebes, and a 20,000-mile annual commuter, the arctic tern. Sea birds abound along the coast, grouse and ptarmigan live in uplands, and some 40 songbird species summer here. Seacoast rock pinnacles and lakeshore treetops are nest sites for bald eagles, hawks, falcons, and owls. Brown bears and moose live in both coastal and lake regions. Moose feed on willows, water plants, and grasses. Caribou, red fox, wolf, lynx, wolverine, river otter, mink, marten, weasel, porcupine, snowshoe hare, red squirrel, and beaver all live here. At the coast are sea lions, sea otters, and hair seals, with beluga, orca, and gray whales sometimes using Shelikof Strait.


People have been coming to the place we call Katmai for thousands of years. Some found a good life in the heart of the park near the present-day Brooks River. Others made their lives on islands and shores of the rugged Shelikof Strait. The Alaska Peninsula’s rich natural resources brought these people to this land of fierce storms, high seas, and steaming volcanoes.Streams filled with salmon, tundra plains covered with migrating caribou, and ocean shores teeming with life were the attraction. Some came to stay, building partially underground homes to protect them from the howling winds and frigid winter temperatures. Others came to take advantage of rich summer salmon runs, building summer shelters but retreating from the mountains for winter. Many traveled through the park, crossing from the east side of the peninsula to Bristol Bay. The trail over Katmai Pass was not only a link between peoples but a route that gave access to a greater variety of food sources and to a rich sharing of both stories and cultures.For over 9,000 years people have called Katmai home. Concentrations of prehistoric sites in the Brooks River and Amalik Bay areas are recognized as national historic landmarks. Several other prehistoric and historic sites are listed on the National Register of Historic Places, including the Savonoski Archeological District.Today the abundant natural resources of Katmai National Preserve provide critical food supplies for descendants of those earliest inhabitants. Native Alaskans who live a subsistence lifestyle harvest fish and game here, intimately linking their lives with the life of this land.

Eruption! And the Valley of Ten Thousand Smokes

It was apparently a nameless valley when the 20th century’s most dramatic volcanic episode happened. Robert Griggs, exploring the volcano’s aftermath for the National Geographic Society four years later, stared awestruck off Katmai Pass across the valley’s roaring landscape riddled by thousands of steam vents. And so Griggs named it The Valley of Ten Thousand Smokes.The June 1912 eruption of Novarupta Volcano dramatically altered the Katmai area. Severe earthquakes rocked the area for a week before Novarupta exploded with cataclysmic force (diagram at right). Enormous quantities of hot, glowing pumice and ash were ejected from Novarupta and nearby fissures. This material flowed over the terrain, destroying all life in its path. Trees upslope were snapped off and carbonized by blasts of hot wind and gas.For several days ash, pumice, and gas were ejected. A haze darkened the skies over most of the Northern Hemisphere. When the eruptions subsided, over 40 square miles of once lush green land lay buried by volcanic deposits that were up to 700 feet deep. In nearby Kodiak, for two days you could not see a lantern held at arm’s length. Acid rain caused clothes to disintegrate on the clothesline in distant Vancouver, Canada. The eruption was over 10 times stronger than the eruption of Mount Saint Helens in 1980. Eventually Novarupta fell dormant again. In the formerly lush valley, gas and steam escaped from the countless small holes and cracks in the volcanic ash deposits.”The whole valley as far as the eye could reach was full of hundreds, no thousands —literally, tens of thousands—of smokes curling up from its fissured floor,” Robert Griggs wrote in 1916. A thousand steam vents reached 500 feet in the air, with some reaching over 1,000 feet.Just two eruptions in historic time—Greece’s Santorini in 1500 BCE (Before Common Era) and Indonesia’s Mount Tambora in 1815—displaced more volcanic matter than Nova-rupta. The 1883 eruption of Krakatoa, also in Indonesia, belched out just over half as much yet killed 35,000 people. The vastly isolated Novarupta’s eruption killed no one. Had it occurred on New York City’s Manhattan Island, Robert Griggs calculated, people in Chicago would hear it plainly. The fumes would tarnish brass in Denver. Acidic raindrops would burn your skin in Toronto. In Philadelphia the ash would lie nearly as deep as this brochure is wide. Manhattan would have zero survivors.Today you can make the trip from Brooks Camp out to the Valley of Ten Thousand Smokes, where a turbulent Ukak River and its tributaries are still at work cutting deep gorges in accumulated volcanic ash. The landscape slowly recovers. In the natural world of stupendous Earth forces, destruction often leads to creation of new life and new landscapes.

What Blew? Geologic Illustration and Text

Robert Griggs thought Mount Katmai had blown—he found its new crater lake. But it was Novarupta Volcano that blew. A deeper source of magma intersected Mount Katmai’s older magma chamber and the surface, so that both erupted through Novarupta—and caused Mount Katmai’s summit to collapse.Illustration caption: Novarupta (”new eruption”) Volcano (color photo pictured right--see the “Photo Descriptions: Eruption! And the Valley of Ten Thousand Smokes section”). Illustration description: The inside of the volcano is depicted in gray with horizontal lines running through it. A blue sky is behind it on the surface. On the left is a small orange circle filled with many black dots about midway from the bottom of the volcano, which is labeled “Mount Katmai.” Connected at the top of the circle is a black line that widens once it reaches the surface. From the bottom portion of the volcano traveling upwards to the right is a wide arrow that crosses part of the orange Katmai circle and tapers as it travels towards the surface. The arrow is labeled “Novarupta.” A line of black dots from the orange Katmai circle migrate into the wide orange arrow and also travel upwards. At the tip of the arrow, which is where the surface meets the sky, smoke billows upwards. Illustration credit: NPS

Accommodations and Services

A concessioner offers meals and lodging at Brooks Camp from about June 1 to mid-September (lodging reservations required). Private lodges offer meals and lodging in King Salmon. Limited camping and food supplies and fishing tackle are sold at Brooks Lodge. Commercial operators provide air taxi, flightseeing, backpacking, canoe, and fishing guide services in the park and preserve. Visit the park’s website for a list. The National Park Service conducts guided walks and evening programs at Brooks Camp in summer.
Seeing Katmai: A 23-mile dirt road leads from Brooks Camp to the Valley of Ten Thousand Smokes. A foot trail descends to the valley from road’s end. A concessioner’s bus makes daily round-trip excursions to the valley from Brooks Camp. Charter aircraft at King Salmon, Homer, Kodiak, and Brooks Camp offer scenic flights. In good weather you may see bays, fjords, and waterfalls on the coast, glacier-clad mountains’ steaming volcanic peaks, and island-studded lakes. You may fly over the Valley of Ten Thousand Smokes and site of the 1912 eruption. Backcountry Travel: Katmai’s rugged wilderness requires reasonable precautions. Be well prepared and equipped. There are several good short routes and unlimited opportunities for long trips. Katmai has few trails, but passable routes are found along river bars, lakeshores, and gravel ridges. For overnight Valley hikes, arrange a bus drop-off and pick-up. Hiking Safety: Cold winds and icy waters are hazards. Your gear must withstand blowing rain and high winds of 50–60 mph. Carry extra dry clothing. Read up on hypothermia symptoms and their treatment. Be prepared to wait out storms: carry matches, a first aid kit, and emergency food. Rains or melting glaciers can make stream crossings impossible. You need sneakers and hiking boots here. Be extremely cautious when crossing muddy waters. Streams rise quickly with rainstorms or heavy glacial melt. Camping: Backcountry users must store food properly. Bear-resistant containers are available in limited supply at Brooks Camp Visitor Center or King Salmon. There are no improved campsites or food caches in the backcountry. Brooks Camp Campground (fee charged; reservations required in advance of arrival) has water, vault toilets, a food storage cache with limited space, and picnic tables. Cooking is allowed on camp stoves only. The concessioner sells white gas for stoves. Meals are available at Brooks Lodge; otherwise bring all your food with you.

Regulations and Safety

Bear Warning: Katmai is a wildlife sanctuary. Bears, moose, and other animals are unpredictable and can be dangerous. Read and study the park leaflet about bears. Ask any ranger about special precautions for backcountry camping, fishing, camping, and hiking. Do not continue to fish near bears. At Katmai brown bears may come very close to you. The safety of yourself, others, and the bears depends on you. Camping and Food Storage: Within 1.5 miles of Brooks River Falls camping is allowed only in the established campground. All food and gear must be secured in a building or in an approved bear-resistant container. Within Brooks Camp, picnicking (the consuming of food) is permitted in designated areas only. Fishing: An Alaska fishing license is required; all state rules apply. Sport fishing is allowed in the park using only artificial lures; fly fishing only from Lake Brooks to the Brooks River foot bridge. Release a fish or cut your line when a bear approaches. For current information and special regulations, please refer to the official State of Alaska fishing regulations or ask at the visitor center. Boating Safety: State and federal boating regulations apply. Water conditions change rapidly with little warning. Kayaks or canoes are safer traveling near shore. Watch the weather and stay ashore in rough water conditions. Bears and Other Large Mammals: Persons may not intentionally approach or remain within 50 yards of a bear or any large mammal, except when on the bear-viewing platforms.

Map: Katmai National Park and Preserve

The map of the park and its surrounding area takes up two-thirds of side two. At the top center of this map is a tiny map of Alaska that locates the park within the state. Katmai National Park and Preserve lies at the base of the Alaska Peninsula in Alaska’s southwest. In the lower right corner, is a small map of the Brooks Camp vicinity where most amenities are located. Brooks Camp is described under its own section. The park map is described below.The main map is oriented with north at the top and shows all of the national park and adjacent national preserve. Together, their area of 4.1 million acres forms an irregularly-shaped rough circle. Text states that “All islands within 5 miles of the mainland are included in the park. The water and submerged land seaward of the coasts, beyond the mean high tide line, are not included.” The map legend indicates that about two and one quarter inches equals 20 miles and a little less than one and one half inches equals 20 kilometers.The park’s topography indicates a mountainous region with a complex system of connecting creeks and rivers and a multitude of lakes. Most amenities are found within the center section of the western area of the park where Brooks Camp and the park’s visitor center is located.At 12:00 on the map on the northern border of the park is Kukaklek Lake. Right below it is a small portion of land labeled as Katmai National Preserve. Below it is Nonvianuk Lake. The much larger mass of land is identified as Katmai National Park.At nine o’clock on the map is the town of King Salmon where the King Salmon Visitor Center, Park Headquarters, and a commercial airport are located. It is about ten miles outside of the park’s boundary at about the middle point of the park’s north-to-south traveling western border.Due west of King Salmon and right inside of the park’s boundary is Lake Camp where there is a boat launch, restrooms and picnicking. Just west of Lake Camp and continuing further west into the park is Naknek Lake. The lake is long, running east-west with a number of lakes connecting off of it. Further west within the lake and closer to the area labelled as the lake’s “North Arm” is Brooks Camp where you can find camping, lodging, and dining. In this area is also Lake Brooks (to the south of Naknek Lake) and the Iliuk Arm.There is only one road in the entire park and preserve, which is unpaved. This road does not connect to any other roads outside the park. It starts at Brooks Camp and travels in a southeasterly direction into the center-southern area of the park. The road leads to the Three Forks Overlook, where there is a shelter and the Valley of Ten Thousand Smokes, which is the valley area of ash flow from the 1912 eruption.The eastern edge of the park is a rugged coastline, with many inlets and bays along the Shelikof Strait in the southern half of the eastern border. Amenities and services along the eastern border of the park from north to south are the Swikshak Patrol Cabin ranger station, the Hallo Bay Wilderness Camp where there is lodging, the Katmai Wilderness Lodge where there is lodging, and the Amalik Bay Patrol Cabin ranger station.Along the eastern border, just inland from the coast, is a chain of mountains and volcanoes oriented roughly southwest-northeast. Numerous rivers are shown draining off these mountains toward the ocean. On the other side of these mountains, particularly within the southern section, the rivers flow onto flat lands and then form the large lakes some which were already mentioned within the Brooks Camp area. The lakes are generally elongated and oriented roughly east-west.Bodies of water and land surround the park. At the top and going clockwise they include: Iliamna Lake, McNeil River, State Game Sanctuary, Kamishak Bay, Cook Inlet, Shelikof Strait, Upper Ugashik Lake, the Alaska Peninsula Wildlife Refuge, Berchoff Lake, Berchoff National Wildlife Refuge and the Alagnok River.

Brooks Camp Map

This map shows an area about one mile by one mile, oriented with north at the top. The facilities at Brooks Camp include the visitor center, restroom locations, the campground, and the picnic area. Brooks Lodge is in this area and its amenities include lodging, food service, showers, and restrooms.A portion of the Naknek Lake is to the east and Lake Brooks is in the southwest corner. The Brooks River connects Lake Brook to Naknek Lake. Trails to access bear viewing locations are at the Falls Platform and Riffles Platform, both of which are close to each other and the Brooks River in the western area of the map. The Lower River Platform is in the eastern section of the map, also on Brooks River, but close to Naknek Lake. The meeting location for the bus to the Valley of Ten Thousand Smokes is near the Lower River Platform. There is also a trail to the Cultural Site and an auditorium is in the vicinity.
