Katmai National Park

Log in to track your visit to Katmai National Park.

Katmai National Park and Preserve on the Alaska Peninsula protects 4 million acres of volcanically active wilderness and hosts what many wildlife photographers and naturalists consider the greatest wildlife spectacle on Earth: brown bears catching sockeye salmon at Brooks Falls. Each summer, sockeye salmon by the millions return from the Pacific to spawn in the Naknek River drainage, and the brown bears of Katmai — over 2,200 of them, one of the densest brown bear populations in the world — converge on Brooks River to intercept them. At peak times in July, dozens of bears may be fishing simultaneously at Brooks Falls, a 6-foot cascade that salmon must leap to continue upstream. The bears' fishing techniques range from stand-and-wait at the lip of the falls (where leaping salmon fall directly into open mouths) to shallow water chasing to deep water diving. It is a spectacle unmatched in the wild anywhere in the United States. The park's second great distinction is geological: the Valley of Ten Thousand Smokes, created by the June 6, 1912 eruption of Novarupta volcano — the largest volcanic eruption of the 20th century — buried an entire river valley under hundreds of feet of ash and pumice. Today the valley is a dramatic, moon-like landscape of eroded ash deposits sculpted into badlands, a stark reminder of the raw geological forces underlying the entire Alaska Peninsula.

Bear viewing at Brooks Falls is the park's centerpiece experience and one of the most thrilling wildlife encounters available anywhere on the planet. The Brooks Falls Viewing Platform accommodates 40 visitors at a time, with rangers managing access to ensure everyone gets time on the platform — peak viewing in early-to-mid July when the first salmon run peaks, and again in September when coho salmon runs bring the bears back. The Brooks Camp area also has a river viewing platform and a lower lagoon platform for observing bears fishing in the shallower sections. The Fat Bear Week event each October — now an internationally followed online competition where the public votes on which bear has gained the most weight for hibernation — has brought worldwide attention to Katmai's remarkable bear population. The Valley of Ten Thousand Smokes is accessed by a daily bus from Brooks Camp (late June through mid-September), a 23-mile drive on gravel road to a trailhead where the Robert Griggs Trail descends into the valley on a 6-mile round trip through a landscape unlike anything else in the national park system. Fly-fishing for rainbow trout, Arctic char, and grayling in the park's clear rivers is world-class, with Brooks River producing trophy-sized fish. Wilderness kayaking in Kukak Bay and Hallo Bay offers the possibility of bear viewing without the crowds of Brooks Camp. Flightseeing tours over the volcanic landscape and the stunning coastline are operated by air taxis from King Salmon and Homer.

Katmai's brown bears are the undisputed stars, but the park's wildlife roster extends well beyond them. The Alaska Peninsula is the meeting point of Pacific marine and Interior terrestrial ecosystems, creating remarkable diversity. Moose wade in the park's lakes and river systems. Caribou from the Mulchatna and Alaska Peninsula herds pass through seasonally. Sea otters, harbor seals, and Steller sea lions inhabit the park's extensive coastline along Shelikof Strait. Orca pods and humpback whales patrol the offshore waters. Bald eagles are abundant and compete with bears for fish scraps. Wolves, wolverines, and red foxes patrol the backcountry. Arctic terns, tufted puffins, and horned puffins nest on offshore rocks.

Katmai is accessible only by small aircraft from King Salmon, Alaska — fly into King Salmon on commercial jets from Anchorage (45-minute flight, daily service), then take an air taxi to Brooks Camp (15-minute flight) or other destinations within the park. There is no road access. Brooks Lodge is the only in-park lodging and must be booked through the park concessionaire (katmailand.com) — it books up over a year in advance for peak July viewing. Brooks Camp campground reservations are also competitive and managed through Recreation.gov. The entrance fee is $15 per person. The park is open year-round in name, but all services operate only June through September.

Fly from Anchorage to King Salmon Airport (AKN) on Alaska Airlines or Ravn Alaska — flights take about 45 minutes. From King Salmon, air taxis fly to Brooks Camp in 15 minutes. Floatplane service also serves remote coastal destinations within the park. Homer, Alaska (120 miles by air) serves as an alternative gateway for coastal Katmai destinations. There is no road connecting Katmai to the road system, and King Salmon is the only practical jumping-off point for most visitors.

Book Brooks Lodge or campground reservations the moment they open — typically in late November for the following summer. If you can't get lodging inside the park, day trips via floatplane from King Salmon or Homer are widely available. Check the NPS Fat Bear Week page in late September for the annual bear weight-watching extravaganza — a genuinely entertaining conservation-awareness program. Bear spray is not typically necessary at Brooks Falls (you're on an elevated platform), but is essential for backcountry travel. Bear etiquette training is mandatory for all visitors at Brooks Camp check-in — pay attention, it's brief and genuinely useful.
