Crater Lake
Crater Lake inspires awe. Native Americans witnessed its formation 7,700 years ago, when a violent eruption triggered the collapse of a tall peak. Scientists marvel at its purity—fed by rain and snow, it’s the deepest lake in the USA and one of the most pristine on Earth. Artists, photographers, and sightseers gaze in wonder at its blue water and stunning setting atop the Cascade Mountain Range.

When to go
July, August, and September are your best bets for warm, dry weather. In May, June, and October, sunny days alternate with periods of rain and snow. Winters at Crater Lake are long and snowy. Storms from the Pacific Ocean dump an annual average of 41 feet (13.5 meters) of snow at park headquarters.
When it's raining or snowing, the lake is usually hidden by clouds. Crater Lake is completely invisible about 50% of the time in the winter!
