A:Only two of Alaska’s eight national parks are accessible by road. Lake Clark isn’t one of them. The fly-in park is located on the upper end of the Alaska Peninsula, across Cook Inlet from the Kenai, and it’s a go-to destination for hikers in the 49th state. If you're short on time or patience, a small network of day hiking trails leaves from the visitor's center in Port Alsworth. Backpackers can find plenty of challenges in the park's trail-free backcountry. Take your pick of alpine tundra, glacier travel, or coastal routes, and bring a map and compass.
