This Alaskan national park features an active volcano that erupted in both 2009 and 1989, but its most famous feature may be its human element: the post-humous documentary “Alone in the Wilderness” was filmed here, furthering Lake Clark’s notoriety as a sanctuary for human solitude.

Richard Proenneke’s cabin, handmade in 1968 without any power tools, not only remains standing- it’s listed on the National Register of Historic Places. You’ll find it on Twin Lakes, a 25-mile hop, skip, and jump from the lake that gives this place its name: Lake Clark National Park.

Air taxis first came to the park in 1942 and remain the best method of navigating and enjoying the park’s full scope. It’s jagged jade mountains, surreal aqua lakes, and jaw-dropping waterfalls give way to some of the best kayaking, rafting, fishing, hiking, camping, wildlife spotting, and sport hunting in the world. Yet it remains one of the least traveled of all national parks, waiting to be joined in solitude.
