Founded in 1902, Crater Lake National Park is home to the deepest lake in America, which was formed by a volcanic eruption approximately 7,700 years ago. A scenic 33-mile driving route runs around the rim of the crater, providing plenty of spectacular views, and visitors can also hike down to the lake to fish and swim. Between early July and early September, narrated boat rides take visitors around the entire lake.

The park is open during the winter as well, and although the lake is frozen over, visitors can cross-country ski, snowmobile, and participate in ranger-guided snowshoe tours.
