Crater Lake National Park
Crater Lake National Park was dedicated in 1902 and encompasses 645 km2 (250 mi2) of pristine forested and alpine terrain, including the lake itself, virtually all of Mount Mazama. The Park is classiﬁed as wilderness and is administered by the National Park Service. It is always open, but some of the roads and facilities are closed during the winter months. Approximately 500,000 people visit Crater Lake each year, and in the summer months visitors can participate in hiking, boat tours, trolley tours, ranger-guided programs, swimming, fishing, camping, and many other activities. In the winter, rangers lead snowshoe hikes on the weekends and cross-country skiing is available on many trails.
