Lake Clark National Park and Preserve covers 4,030,006 acres with a coastline on Cook Inlet, and its highest point is Redoubt Volcano, 10,197 feet. It had 19,778 recreation visits in 2025, up 6.9% on 2024, and 91.8% of them came in June, July and August. No road reaches it.

Lake Clark became a national monument on 1 December 1978 and a national park and preserve on 2 December 1980. The park has two active volcanoes, Iliamna and Redoubt. We read the figures below on 29 October 2026 on the park's own pages and alerts, one air operator's site, Recreation.gov, the Park Service's visitor statistics and NOAA's normals.

How do you fly into Lake Clark with no road to the park?

Visitors reach Lake Clark by small plane, because the park is not on the road system. The Park Service says access is primarily by small aircraft. Fixed-wing planes may land on all suitable lakes, rivers, beaches, gravel bars and open ground unless an area is closed.

The park's own distances are about 120 air miles from Anchorage and 65 from Homer. By our own arithmetic, those figures measure to the park's nearest edge on the Cook Inlet coast, not to Port Alsworth on Lake Clark itself. The flight times below are the Park Service's wording, not timetables.

No Park Service page we read names a scheduled airline to Port Alsworth. The park lists authorised air taxis from Anchorage, Homer, Kenai or Soldotna, King Salmon, Kodiak, Port Alsworth and other towns. It says the lists are not endorsements, and it prices none of them.

Boats reach only the coast, across the open water of Cook Inlet, and the Park Service says those charters are not regularly scheduled. It advises a few extra days on each side of a trip, because weather delays are normal. A pickup can be late by several days.

Why do wheels or floats decide a Lake Clark trip?

Lake Clark's landing places split by landing gear: Port Alsworth and the coastal beaches need wheels, and the inland lakes need floats. The Park Service says it would be unrealistic to visit Crescent Lake and Silver Salmon Creek on the same trip. No place between them lets you switch planes or gear.

Silver Salmon Creek and Chinitna BayWheels, on the beachBear viewing on the coast

Crescent LakeFloatsSalmon, brown and black bears
Frozen lakes in winterSkis or wheel-skisSome areas, when conditions allow

The Port Alsworth runways belong to Lake Clark Air and Lake and Peninsula Airlines, which charge a ramp fee. Other air taxis may therefore decline to fly there. At Upper Twin Lake there is no beach or runway suitable for a wheeled plane.

On the coast, the tide decides where a plane can sit. The Park Service tells pilots to use the Seldovia tide chart and add half an hour. It warns that a wheeled plane parked too low ends up in the water.

What does Lake Clark cost when the park charges nothing?

Lake Clark charges no entrance fee: the Park Service says an entrance pass is not required. There is nothing to pay on arrival, in cash or by card. Backpacking, camping, river running, bear viewing and a visit to Proenneke's cabin need no fee or permit either.

Lake Clark is not on the 2026 list of eleven parks that charge visitors from abroad a $100 surcharge. Our guide to national park fees for international visitors lists the parks that do.

The money goes on the plane. The one fare we could read is Smokey Bay Air's, from Homer: $1,145 a person, with a two-person minimum, for a trip of about five hours. That is about an hour's flight each way and three hours on the beach, to Katmai or Lake Clark. Two people therefore pay $2,290 before any lodge.

The operator's page carries no date and no year on the price, so treat it as one example rather than the going rate. Its terms refund half the price if no bears are seen. The park itself prices only its two public-use cabins, at $45 and $65 a night. Anglers and hunters need an Alaska state licence.

Where do bears gather at Chinitna Bay and Silver Salmon Creek?

Lake Clark's bear viewing is on the Cook Inlet coast, at Chinitna Bay in the south and Silver Salmon Creek midway up the shore. The Park Service says visitors at Chinitna Bay can see "as many as twenty coastal brown bears from a single location". Both places are less than an hour's flight from Homer, Kenai or Anchorage.

The bears' calendar follows their food. They graze the sedge meadows from late spring to mid-summer, dig clams on the tidal flats, and move to the rivers in late summer when the salmon run. The Park Service gives no month-by-month count of bears on the coast.

Chinitna Bay has two designated viewing sites with trails, and the park asks visitors to use them. Watching fishing bears is harder there, because the head of the bay is private property. The sedge meadow beyond the river is closed to camping and all other entry from 1 May to 31 August. Picnicking above the beach is barred from Glacier Spit to the ranger cabin, 2 miles east, from 1 June to 31 August.

Silver Salmon Creek's sedge meadow, between the Sargent Creek confluence and the creek itself, is closed to people from 15 June to 15 September. Visitors stay on the footpath. Lodges carry their guests in ATV trailers, and everyone else walks a few hundred yards of sand to the nearest meadow.

The Park Service's Lake Clark pages give no minimum distance from a bear in yards, so do not carry another park's rule here. Its advice is to use the same viewing sites as others, stay visible, and never approach or crowd a bear. Groups should stay within a few arms' lengths of each other. Anyone who digs clams does so at their own risk, since the shellfish are not monitored for paralytic poisoning.

Katmai National Park and Preserve lies to the south; the Park Service places Lake Clark north of it.

When is Proenneke's cabin at Upper Twin Lake open?

Proenneke's cabin was open daily from 10 a.m. to 4 p.m. in the 2026 summer season, from late May to late September. The Park Service calls the May date tentative, since the spring opening depends on the ice. The cabin is locked in winter, though the area can be explored all year, and a visit is free.

Dick Proenneke first saw Upper Twin Lake in 1962 and arrived in 1967, aged 51. One Park Service page says he built the cabin in the summers of 1967 and 1968; another says construction began in 1968. He built it by hand, with many tools he made himself, and lived in it for about thirty years.

The cabin measures roughly 12 by 16 feet, with peeled spruce logs, a sod-and-moss roof and three windows. Proenneke last visited it in 2000, aged 84, and it was listed on the National Register of Historic Places in 2007. A 27-minute documentary filmed in 1977, "One Man's Alaska", is free to watch online at the National Archives.

Rangers and volunteers live nearby from late May to late September and lead tours in summer. Visitors cook and eat outside, and nobody may sleep in the cabin, the cache or the woodshed. Camping is banned inside the historic boundary.

The only designated camp is Hope Creek, a primitive area taken first come, first served, with a 14-day limit from 15 April to 30 September. Reaching the cabin from it means crossing Hope Creek, which may be impassable in flood or at spring breakup. Within half a mile of the lakeshore, food must be kept in a bear-resistant container.

What does Port Alsworth offer a visitor without a road or a shop?

Port Alsworth is the park's field headquarters and the site of its visitor centre, on the southern shore of Lake Clark. The Park Service says the town is not connected to a road system and has no grocery stores. It is a private community with lodging, air taxis, guides, gear rental and a post office.

The visitor centre stands midway up the easternmost runway and is open in summer only. The Park Service publishes no season dates or hours for it, and its visitor centres page read "Page In-Progress" on 29 October 2026. In winter, visitors contact staff at the headquarters building next door, and the park's number is 907 644-3626.

The visitor centre lends bear-resistant food containers free, and a fat-tyre wheelchair that works on gravel, delivered to your plane if booked by phone. Runways cross the roads in town, so expect to walk and to cross at the very end of a runway. There is no mobile phone service in the park, and the Park Service suggests a satellite phone or messenger.

All lodging and meals are on private property, because the park has no concessioner. The Park Service lists eight places to stay in Port Alsworth, including a bed and breakfast, and one private campground. It prints no prices. Anyone not staying at a lodge must bring all their own meals.

Which trails start from Port Alsworth and the Joe Thompson cabin?

Lake Clark's only maintained trails are the Tanalian Trails from Port Alsworth and the Portage Creek Trail from the Joe Thompson cabin. The rest of the park is trail-free wilderness. The distances below are the park's own figures.

WalkDistanceWhat is there
Beaver Pond Trail3.2 miles round tripThe shortest walk on the park's list
Tanalian FallsAbout 4 miles round tripA 30-foot waterfall over ancient lava
Kontrashibuna LakeAbout 5.5 miles round tripA walk into designated wilderness
Tanalian Mountain8.6 miles round tripA steep climb of at least eight hours
Portage Creek TrailAbout 3.25 milesOpen tundra, from the Joe Thompson cabin

Off the trails, the Park Service tells hikers to plan on one mile an hour. There are rivers to ford, bogs to avoid and no bridges anywhere in the park. Backcountry permits are not required, and an itinerary form at the visitor centre is voluntary; the park does not track anyone's progress.

The Park Service names several backpacking routes. One is the Telaquana route, an ancestral Dena'ina path from Kijik to Telaquana Lake; another runs from Upper to Lower Twin Lakes.

How do you book the Priest Rock and Joe Thompson cabins?

Lake Clark's two public-use cabins, Priest Rock and Joe Thompson, are booked on Recreation.gov, and they are the only thing in the park with a fee. All other camping is primitive, with no facilities and no designated sites. Both cabins stand on Lake Clark and are reached only by floatplane or boat.

CabinWhereSleepsPrice a night
Priest Rock8 miles north of Port AlsworthSix$65 on the Park Service page
Joe Thompson13 miles north-east of Port AlsworthThree$45, Park Service and Recreation.gov

Recreation.gov printed no fee for Priest Rock on 29 October 2026, so its $65 comes from the Park Service page alone. Both cabins have a wood stove and no electricity or water. Guests bring their own stove, bedding and water treatment, and pack out all their rubbish.

A stay may last five nights in a row and 21 nights a year. Water taxis may be available from Port Alsworth. On 29 October 2026 Recreation.gov showed spring 2027 dates as not yet released, and we could not find when they open.

Lodges elsewhere in the park are private too. The Park Service lists them on Lake Clark, at Upper Twin Lake, Tuxedni Bay, Crescent Lake, Silver Salmon Creek and Chinitna Bay. It says to contact each one for prices. It calls Crescent Lake the park's most visited destination.

How cold and wet is Port Alsworth beside the Cook Inlet coast?

Port Alsworth averages a high of 69.1°F in July, its warmest month, and 24.0°F in January. The town gets 13.07 inches of precipitation a year, with the most in September, 2.57 inches. The Cook Inlet coast is far wetter: the Park Service gives it 40 to 80 inches of rain a year and calls it often foggy.

October44.3°F / 31.9°F47.1°F / 33.3°F42.0°F / 30.7°F

The table gives NOAA's 1991 to 2020 average highs and lows. Port Alsworth gets 87.9 inches of snow a year, a figure NOAA marks provisional, and December is its snowiest month. NOAA publishes no normals for the coast at Silver Salmon Creek.

The Park Service says gusts of 30 to 50 mph are not uncommon. Frost and snow can come at any time, most often from September to early June. Lake Clark usually begins to freeze in November and melts in April, and the ice decides whether a plane lands on floats or skis.

What is open at Lake Clark once the lake starts to freeze?

Lake Clark is open 24 hours a day all year, but most visitors arrive between June and October, when more lodging, transport and guiding is available. July was the busiest month in 2025, with 7,087 of the year's 19,778 visits, ahead of August with 6,096 and June with 4,976. September had 1,084.

In winter, planes on skis reach parts of the park when the weather allows. The Park Service lists ski-equipped air taxis from Anchorage, Chugiak, Kenai or Soldotna and King Salmon, and none from Port Alsworth. The visitor centre is closed, and Proenneke's cabin is locked.

On 29 October 2026 the park's alerts feed was empty. An empty feed says only that no alert was posted: the meadow closures and the cabin season are on the park's ordinary pages.

Lake Clark keeps Alaska time, the same clock as Anchorage. NIST gives 2 a.m. on 1 November 2026 as the end of daylight saving time and does not list Alaska among the places that skip it. Our guide to Alaska compares the state's other national parks, from Kenai Fjords National Park to Katmai National Park and Preserve.

The other national parks in Alaska are Denali National Park, Gates of the Arctic National Park and Preserve, Glacier Bay National Park and Preserve, Katmai National Park and Preserve, Kenai Fjords National Park, Kobuk Valley National Park and Wrangell–St. Elias National Park and Preserve.

Questions before you go

  • Does Lake Clark National Park charge an entrance fee?

    Lake Clark National Park and Preserve charges no entrance fee, and it is not on the 2026 list of eleven parks with a $100 surcharge for non-residents. Backpacking, camping, bear viewing and a visit to Proenneke's cabin need no fee or permit either. The only things the park prices are its two public-use cabins, at $45 and $65 a night.

  • Can you drive to Lake Clark National Park?

    Lake Clark National Park cannot be reached by road; the Park Service says access is primarily by small aircraft. It puts the park about 120 air miles south-west of Anchorage and 65 north-west of Homer. Flights from Homer, Kenai or Anchorage to Port Alsworth, the park's headquarters town, take about an hour to 1.5 hours.

  • Where can you watch bears in Lake Clark National Park?

    Lake Clark's bear viewing happens on the Cook Inlet coast, at Chinitna Bay and Silver Salmon Creek, less than an hour by wheeled plane from Homer, Kenai or Anchorage. The bears graze sedge meadows from late spring to mid-summer and fish for salmon in late summer. Parts of both meadows are closed to people for most of the summer.

  • When is Proenneke's cabin open to visitors?

    Proenneke's cabin at Upper Twin Lake was open daily from 10 a.m. to 4 p.m. in the 2026 summer season, which runs from late May, depending on the ice, to late September. The cabin is locked in winter. In summer only floatplanes can land there, about 30 minutes from Port Alsworth.

  • How much does a bear-viewing flight to Lake Clark cost?

    A bear-viewing flight to Lake Clark from Homer costs $1,145 a person on Smokey Bay Air's own page, with a two-person minimum, for a trip of about five hours. The operator flies to Katmai or Lake Clark and does not say which on a given day. Its page carries no date, and the Park Service prices no air taxi.
