The Best Hikes in Lake Clark for Every Experience Level
Lake Clark is one of the most remote national parks in the United States. No road leads here. You arrive by seaplane or wheeled aircraft from Anchorage, step onto a tundra shoreline, and find your way from there. There is no large-scale network of marked trails, no shuttle, and no cell service.
If you only do one hike, make it Tanalian Falls, accessible from Port Alsworth (about 3.1 miles round-trip, easy). It's the park's only truly marked hike and the ideal introduction for a first visit. To go farther, hike Tanalian Mountain for alpine views of the volcanoes, or spend several days in the backcountry around Twin Lakes if you're an experienced hiker.
Preparing for Your Lake Clark Hike
Permits and Entrance Fees
Lake Clark is free to enter, and no permit is required for day hikes. For backcountry camping, it's a good idea to register with the rangers in Port Alsworth before you leave. It isn't legally required, but it's a basic precaution in such a remote setting.
Brown Bears: What to Do
Lake Clark is home to a dense brown bear population. In the coastal area around Chinitna Bay, bears may be just a few feet away during wildlife-viewing outings. Keep bear spray immediately within reach, not buried at the bottom of your pack. Never run. Talk loudly as you move through dense vegetation so you don't surprise an animal. For advice on how to respond in different situations, see the Lake Clark wildlife guide.
Water, Communications, and Gear
There is no cell service in the park. A satellite communication device such as a SPOT or Garmin inReach is strongly recommended for any hike beyond Port Alsworth. Filter or purify water from lakes and rivers. Temperatures can drop by 18°F in just a few hours, even in July, so a waterproof windbreaker and insulating layers are essential.
Dogs
Dogs are allowed on a leash throughout most of the park. In practice, they're strongly discouraged because of the area's abundant wildlife. Check area-specific restrictions with the ranger office in Port Alsworth.
Opening Hours and Services
The park is open 24 hours a day, 7 days a week, year-round. Visitor services are very limited between Labor Day, in early September, and Memorial Day, in late May. For hiking, the realistic window runs from June through mid-September.
The Best Hikes by Area
Port Alsworth: Marked Trails
Port Alsworth is the only village in the park with a permanent ranger presence and a few clearly defined trails. This is where most hikes begin for visitors who don't have wilderness navigation experience.
Tanalian Falls
3.1 miles round-trip · Modest elevation gain · 2 hours · Easy · Out-and-back
The trail starts at the Port Alsworth visitor center and follows the Tanalian River through a spruce forest. After about an hour of easy walking, you'll reach the falls. The setting is photogenic without being grandiose. It's a pleasant stop that's well suited to families and visitors with only half a day.
Trailhead and parking. Port Alsworth visitor center, with parking on-site.
Seasonal advice. Accessible from early June through late September. Waterproof boots are recommended in spring because of muddy stretches in the forest.
Tanalian Mountain
About 9.3 miles round-trip · Significant elevation gain · 7 to 9 hours · Difficult · Out-and-back
The marked trail ends at Tanalian Falls. Beyond the falls, the route to the summit of Tanalian Mountain is off-trail, crossing alpine tundra and then rock. From the summit, you'll see Lake Clark, the Chigmit Mountains, and, on a clear day, Mount Redoubt and Mount Iliamna. This hike is for hikers in good physical condition who can travel across unmarked terrain.
Trailhead. Same as Tanalian Falls. Beyond the falls, a topographic map or GPS is essential for navigation.
Warning. Snow is possible above 2,950 feet even in July. Leave early so you can return before dark.
Kontrashibuna Lake
About 5 miles round-trip · Little elevation gain · 3 hours · Moderate · Out-and-back
This lightly traveled trail crosses boreal forest and wetlands to Kontrashibuna Lake. The vegetation is more varied than on the climb to the falls, with openings onto tundra and views of the mountains. Beavers, otters, and moose are regularly spotted along the lakeshore.
Trailhead. Port Alsworth. Some sections are wet, so waterproof footwear is essential.
Twin Lakes: Inland Backcountry
Twin Lakes, including Upper and Lower Twin Lake, can only be reached by seaplane from Port Alsworth or Anchorage. This area is for experienced, self-sufficient hikers equipped for several nights on the tundra.
Unmarked Hiking Around Twin Lakes
2 to 7 days · Off-trail · Experienced
There are no marked trails here. You land where the seaplane sets down, read the tundra, work around the marshes, and let the terrain determine your route. The hills above the two lakes offer views across an almost untouched alpine-tundra landscape. Fishing for Arctic char and pike is excellent in both lakes.
Logistics. Voluntary registration with the rangers is recommended before departure. A local guide or outfitter is advisable for a first trip to this area.
Coastal Area: Bays and Brown Bears
The Lake Clark coast, including Chinitna Bay and Tuxedni Bay, can only be reached by floatplane from Homer or Anchorage. This is prime brown bear country in summer, when salmon are migrating upstream.
Walking the Mudflats, Chinitna Bay
Variable · Flat · Easy · Guided off-trail walk
Hiking outings in this area involve walking across coastal mudflats and meadows near salmon streams. Brown bears may be less than 100 feet away. Most visitors go with a guide or from a coastal lodge. This is a wildlife-viewing outing, not a strenuous hike.
Advice. Keep all food inaccessible while walking. Stay in a tight group and move slowly.
Easy, Family-Friendly Hikes
Family hiking in Lake Clark centers on Port Alsworth. Tanalian Falls (3.1 miles, easy, 2 hours) is the park's only marked trail, and it works for kids as young as 6 or 7 who have some walking experience. The route is easy to follow, and the payoff comes quickly.
For young children, walks along the shores of Lake Clark near the village offer an alternative. The terrain is flat, with views of the Chigmit Mountains and little risk of getting lost.
Keep in mind that Lake Clark isn't designed for mass family tourism. Its remoteness, lack of cell service, and bears require constant attention. Our guide to visiting Lake Clark with kids brings together practical advice for planning this kind of trip with children.
Challenging Day Hikes
For a full day out from Port Alsworth, Tanalian Mountain is the clear choice. The off-trail ascent beyond the falls is demanding, with significant elevation gain and unmarked terrain, but the views of the volcanoes and Lake Clark make the effort worthwhile.
If you're arriving with a multiday plan and a seaplane, the Twin Lakes and Turquoise Lake areas offer two- to five-day routes across alpine tundra, with complete self-sufficiency. Plan on covering 5 to 9 miles per day, depending on the terrain.
For the views, choose Tanalian Mountain, with Mount Redoubt in the background. For wildlife, head to the coast around Chinitna Bay, where brown bears gather as salmon migrate upstream in July and August. For complete solitude, choose Twin Lakes, where you can hike for days without seeing another person.
Access, Trailheads, and Parking
Lake Clark isn't connected to Alaska's road system. Parking doesn't work here the way it does in other American parks.
You can reach every area by plane or boat. From Anchorage, the flight takes 1 to 2 hours, depending on the destination. Port Alsworth has an airstrip for wheeled aircraft. The other areas, including Twin Lakes and the coast, are accessible only by floatplane. In winter, frozen lakes serve as runways for ski-equipped aircraft.
The Port Alsworth trails, including Tanalian Falls, Tanalian Mountain, and Kontrashibuna, start right at the visitor center, within walking distance of the airstrip. For other areas, book a charter flight with an air taxi based in Anchorage, Homer, or Port Alsworth.
For air-transport providers and logistics options, see the Lake Clark access information.
When Should You Hike in Lake Clark?
The ideal window runs from June through mid-September. July and August offer the best conditions, with mild temperatures (50 to 64°F inland), more than 19 hours of daylight, and salmon migrating along the coast. The coast gets significantly more precipitation than the interior, so bring rain gear whatever the season.
September is photogenic, as the tundra turns orange and red, but nighttime temperatures fall quickly and snow can return as early as the first weeks of the month. Freezing temperatures are possible throughout the park from September through early June.
