With its sky-high Chigmit Mountain peaks, two active volcanoes, alpine tundra, and turquoise lakes brimming with salmon and so smooth they double as mirrors, Lake Clark National Park and Preserve really is the Last Frontier. The park is only accessible by small aircraft or boat, so this area remains unblemished, and it offers magnificent wildlife sightings of brown and black bears, moose, caribou, and Dall sheep. The 4,030,005-acre national park also allows catch-and-release fishing, with species of salmon—including chum, king, coho, pink, and sockeye—spawning in all main rivers between the months of June and September. Other outdoor adventure includes rafting (don’t expect white-water rapids, though), kayaking, and hiking through the Tanalian Trails network.
When to go: Summer, when the average highs fluctuate between 50 and 65 degrees Fahrenheit (10 and 18 degrees Celsius).
