Awesome Crater Lake truly is truly a natural wonder; one of the clearest, deepest and bluest lakes in the world. A must see on any visit to Oregon, it’s up to 2000 feet deep and fills much of the caldera of an enormous volcano. Most of Crater Lake National Park is near or above 7000 feet elevation and is closed in winter, so you’ll want to plan your visit between late spring and early fall. Note: The road to the top from the north entrance is not for the faint-of-heart driver; enter from the south for a more relaxing trip to the lodge on the rim.
