Lake Clark National Park and Preserve is a large protected area in southwestern Alaska established in 1980 to conserve mountains, volcanoes, glaciers, lakes, and coastal ecosystems. It protects roughly 4 million acres of wilderness.

The park covers a mix of volcanic peaks, glaciated mountains, extensive freshwater lakes and coastal estuaries. Much of the park is alpine and subalpine terrain interspersed with long freshwater lakes and river valleys used by spawning salmon.

Wildlife viewing and backcountry recreation are principal draws - salmon runs attract concentrations of brown bears along streams, and the coastal sections host migratory seabirds and marine mammals. Most visitor activity-fishing, kayaking, bear viewing, and hiking-relies on floatplane access and small-boat travel.

The park was designated in 1980 under the Alaska National Interest Lands Conservation Act and was created to protect fish and wildlife habitat along with traditional Dena’ina Athabaskan subsistence areas. Archaeological evidence and continuous use by Indigenous people predate the park by thousands of years.

Geographically the unit spans parts of the Cook Inlet coast, interior lake systems and the outer edges of the Alaska Peninsula. The small settlement of Port Alsworth lies within the park and serves as the primary access point and visitor service hub.

  • Access: Many areas are accessible only by floatplane or boat; road access is extremely limited, making guided or charter transport the usual arrival method.
  • Best time to visit: Peak summer months are best for viewing salmon runs and coastal brown bears, and for most backcountry activities when snow and ice have receded.
  • Visitor planning: Remote backcountry travel requires self-sufficiency or use of local guides - expect primitive campsites and no extensive trail network in many zones.

What to See #

  • Port Alsworth: A small community on the shores of Lake Clark that functions as the primary visitor gateway; has an airstrip and limited services used by floatplanes and charter operators.
  • Lake Clark: The lake that gives the park its name, set among glacial valleys and used by anglers and floatplane visitors as a base for exploring the park's interior.
  • Chigmit and volcanic highlands: A rugged volcanic and alpine subrange within the park that includes steep glaciated valleys and several active or recently active volcanoes visible from many park locations.
