Katmai National Park

Brown bears, leaping salmon, and a valley of volcanic ash — fly-in Alaska.

National Park ✈️ Drive + Fly State  AK Official site ↗

Katmai is the home of that photograph — the brown bear standing atop a waterfall, jaws open, as a salmon leaps straight into its mouth. That's Brooks Falls, where in July dozens of bears line up to feast on the sockeye run, and where every fall the internet crowns a champion in 'Fat Bear Week.' It is one of the great wildlife spectacles on Earth, and there are no roads to it at all.

You reach Katmai by air: a commercial flight from Anchorage to the village of King Salmon, then a floatplane that lands on Naknek Lake and taxis to the beach at Brooks Camp. From there it's a short walk (after a mandatory bear-safety orientation) to the elevated viewing platforms above the falls. The park's other wonder is geologic: the Valley of Ten Thousand Smokes, the ashy moonscape left by Novarupta's 1912 eruption — the largest volcanic eruption of the 20th century — reached by a ranger bus tour, the only road in the park.

The park is free, but getting there is the expense and the whole logistical puzzle. Brooks Lodge is awarded by a lottery a year ahead; the campground (inside an electric bear fence) books months out. Time it for July's salmon run or September's fat bears, dress for cold, wet, windy weather even in summer, and if you can't make the trip, watch it all live on the Brooks Falls bear cams from home.

Don't miss

Brooks Falls

Brooks River

The world-famous spot — a low waterfall where sockeye salmon leap upstream and brown bears line up to catch them mid-air, viewed from elevated, railed platforms.

Insider tipTwo peaks: early-to-late July for the salmon run and the most bears, and September for the same bears now enormous. The falls platform can hit capacity in July, so arrive early and budget time.

Brooks Camp

Naknek Lake

The hub at the mouth of the Brooks River — visitor center, ranger station, lodge, and campground — and where your floatplane lands.

Insider tipEvery visitor must attend a mandatory bear-safety 'bear school' on arrival. Bears often occupy the trails and the river footbridge, so leave extra time to reach the falls.

Valley of Ten Thousand Smokes

south of Brooks

A 40-square-mile moonscape of compacted volcanic ash carved by rivers — reached by a ranger-narrated bus tour from Brooks Camp on the park's only road.

Insider tipA complete change of scene from the bears — book the full-day bus tour ahead through the lodge, and dress for raw, exposed weather.

Novarupta & Mount Katmai

backcountry

The geologic heart: in 1912 Novarupta erupted some 30 times the volume of Mount St. Helens — the largest eruption of the 20th century — and nearby Mount Katmai's summit collapsed into a deep caldera lake.

Insider tipThese are remote backcountry features; most visitors experience the aftermath via the Valley bus tour rather than reaching the vents.

Naknek Lake

Brooks Camp

The big lake where the floatplanes land and Brooks Camp sits — a hub for boating and trophy rainbow-trout and sockeye fishing.

Insider tipYour arrival lands right on the lake and taxis to the beach by the trailhead.

Coastal bear viewing

Katmai coast

A separate experience along the park's Pacific coast (Hallo Bay, Geographic Harbor), where bears graze sedge meadows and dig clams on the tidal flats — reached by floatplane or boat from Homer or Kodiak.

Insider tipChoose the coast for a wilder, day-trip bear experience without the Brooks Falls crowds — it's an entirely different gateway.

When to go & weather

Cool, wet, windy subpolar maritime — even at the height of summer, daytime highs only reach the low 60s and nights drop into the 40s, with frequent rain and wind. Late summer and early fall (August–September) are wettest. The visitor season runs June through mid-September; the Park Service tells visitors flatly to expect windy, rainy, cold conditions, so pack layers, rain gear, and waterproof boots.

Getting there

There is no road to Katmai's bear country — you fly commercial to King Salmon and then take a floatplane to Brooks Camp on Naknek Lake.

Your basecamp — drive here, stay here

Anchorage, AKStarting point for the Alaska Highway system — no drive to the park; you fly from here

The practical staging hub: multiple daily jet flights to King Salmon (about 1 hour), plus all the gear stores, grocery runs, and lodging you'll need before heading into the backcountry.

The jump-off village for Katmai — home to the small airport where floatplane services load gear and passengers for the 20-minute hop to Brooks Camp on Naknek Lake.

The journey

  1. Anchorage → King Salmon — About 1-hour commercial jet flight; multiple carriers operate this route daily in summer.
  2. King Salmon → Brooks Camp — A roughly 20-minute floatplane flight across Naknek Lake, operated by the park concessioner and licensed air-taxi services based at King Salmon.

Leave the carTed Stevens Anchorage International Airport (if flying in from the Lower 48), or at King Salmon Airport if you drove the Parks Highway up from Anchorage to Kenai and caught a regional flight. There is no road beyond King Salmon.

Book aheadBrooks Lodge is awarded by lottery a full year ahead (Recreation.gov); the electric-fence campground books out in minutes on its January, February, and March opening windows — plan your logistics 9–12 months out.

Not boarding the boat?If you can't make the flight, the Brooks Falls bear cams stream live on explore.org each July and September — the same falls, the same bears, free. You can also stage in Anchorage and take a day tour to see brown bears at McNeil River State Game Sanctuary or Kenai Peninsula as a road-accessible alternative.

Getting in

No roads at all — the access is the trip. Fly to King Salmon, then take a floatplane to Brooks Camp.

Anchorage → King Salmon → Brooks CampVisitor season June–mid Sep

A commercial jet from Anchorage to King Salmon (~1 hour), then a float-equipped air taxi (~20–30 minutes) that lands on Naknek Lake at Brooks Camp. Day fly-in packages and overnight stays both work.

Coastal (from Homer / Kodiak)Summer

For coastal bear viewing (a separate part of the park), floatplanes and boats run from Homer or Kodiak — independent of the King Salmon route.

Where to stay

Reservations are everything here, booked far ahead — a lodge by lottery, a campground months out.

Brooks Lodge

The prime in-park option — a small lodge overlooking the Brooks River, with meals and a handful of rooms. Demand far exceeds supply, so stays are awarded by a random lottery held roughly a year ahead.

Booking tipFlexibility on dates improves your odds; confirm the current year's lottery rules with the concessioner.

Brooks Camp Campground

Reserved through Recreation.gov well in advance (July fills months ahead), enclosed by an electric bear fence with cooking shelters and food caches.

Booking tipStrict food-storage rules apply — follow them to the letter.

King Salmon & wilderness lodges

King Salmon has limited lodging useful as a day-trip staging point, and remote fly-in lodges around the region offer multi-day bear-and-fishing packages.

Booking tipIf Brooks is full, a King Salmon base plus a day fly-in still works.

Know before you go

Is it free? Then why is it expensive?

There's no park entrance fee for Katmai. The cost is getting there — a round-trip commercial flight to King Salmon plus the floatplane to Brooks Camp (a day fly-in commonly runs into the hundreds of dollars per person; lodge stays cost much more).

How do I actually visit?

Fly from Anchorage to King Salmon on a commercial jet, then take a floatplane (about 20–30 minutes) to Brooks Camp, landing on Naknek Lake. There are no roads into the park.

When should I go?

July for the salmon run and the leaping-salmon spectacle (peak bear numbers), or September to see the same bears at their fattest. The visitor season runs June through mid-to-late September.

Is it safe with all those bears? What's 'bear school'?

Yes, with rules. Every visitor attends a mandatory bear-safety orientation ('bear school') on arrival. You stay on the platforms and designated areas, keep prescribed distances, yield trails and the river bridge to bears, and store all food properly.

Day trip or overnight — and how far ahead do I book?

Either works: a day fly-in covers bear school and time at the falls. To stay overnight you need Brooks Lodge (an annual lottery, about a year ahead) or the campground (Recreation.gov, months ahead for July). Book very early.

Can't make the trip?

Watch from home — the Brooks Falls bear cams stream live from roughly late June through mid-October, and the annual 'Fat Bear Week' voting happens online each fall.
