- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.

Katmai is a fly-in park on the Alaska Peninsula, about 470 km (290 mi) southwest of Anchorage and unreachable by road. It was created in 1918 to protect the Valley of Ten Thousand Smokes, the ash flow left by the 1912 Novarupta eruption, and it now holds roughly 2,200 brown bears. Almost everyone goes to Brooks Camp, where platforms overlook Brooks Falls during the July sockeye run. Everything else — Hallo Bay, Geographic Harbor, Moraine Creek, the backcountry — needs a floatplane or boat charter and a guide.

Time out
Finding the local time zone…
Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.
Accessibility
- The Brooks Camp Visitor Center, lodge and the flat path toward Brooks Falls are the most manageable areas, but the site is reached only by small floatplane or boat.
- The Valley of Ten Thousand Smokes bus involves a long rough road and an optional steep descent; the overlook at Griggs Visitor Center is the accessible option.
- No paved roads, boardwalks or wheelchair-accessible trails exist in the backcountry.
Visiting lightly
- Keep the 75 m bear distance and never let a bear get food; a food-conditioned bear is usually destroyed.
- Use the food caches and electric fence at Brooks Camp rather than leaving scented items in tents.
- Book with operators that cap group size at bear-viewing sites and follow NPS closures.
- Pack out everything, including fishing line and food waste.
Questions people ask
How much does it cost to enter Katmai National Park?
Nothing. Katmai has no entrance fee. Your costs are transport and services: a floatplane from King Salmon to Brooks Camp runs roughly US$250–400 return, the Valley of Ten Thousand Smokes bus tour about US$96, and Brooks Camp Campground US$12 per person per night in peak season (2026 estimates).
What are the best hikes in Katmai National Park?
There are almost no maintained trails. The realistic walks are the flat Brooks River path between the visitor center, the falls platforms and the campground (1–2 hours), and the optional descent from Griggs Visitor Center into the Valley of Ten Thousand Smokes — 4.8 km round trip with 240 m of climb back out. Anything longer is unmarked backcountry travel.
When is the best time to visit Katmai National Park?
July for bears: the sockeye run concentrates the most brown bears at Brooks Falls, and the lodge, campground, bus tours and visitor center are all open 1 June–17 September. Late August and early September are quieter with bears still present. Outside that window there are no services and access is by chartered aircraft only.
Can I drive to Katmai National Park?
No. Katmai is about 470 km (290 mi) southwest of Anchorage and has no road connection. You fly commercially to King Salmon, then take a floatplane or boat to Brooks Camp or a coastal site.
Do I need a reservation for Brooks Camp?
Yes for the campground, which must be booked in advance at recreation.gov from 5 January — many July dates fill within hours. Brooks Lodge also requires reservations, usually made a year or more ahead. Day visitors arriving by air taxi still need to attend the bear safety orientation.
How do I see the Valley of Ten Thousand Smokes?
Take the daily bus tour from Brooks Camp along the 37 km park road to Griggs Visitor Center, offered 1 June–17 September and booked through the park concessioner. It crosses boreal forest and tundra, stops for lunch, and allows an optional walk down onto the ash.
Is Katmai the same as Lake Clark or Aniakchak?
No. Lake Clark National Park and Preserve lies northeast of Katmai and is also fly-in; Aniakchak National Monument is further southwest on the Alaska Peninsula and even more remote. All three sit in Southwestern Alaska and are usually visited on separate trips.
