Crater Lake National Park is a wonderful must-see National Park. The lake is breathtakingly beautiful, and you can easily see the entire park in one day. We stayed for three nights at the Crater Lake Resort, which was 25 miles SE of Crater Lake on Highway 62. The campground was comfortable, and offered full hook-ups for $30.00 a night.
We went through the National Park twice, but also had time to explore the surrounding area which included checking out nearby Kimball State Park and Collier Memorial State Park which offers full hookup sites on a first come first serve basis. Collier State Park even offers a logging museum which is quite interesting.
