Crater Lake National Park — Hikes, camping & visitor guide

Crater Lake National Park is a national park of the United States located in southern Oregon. Established in 1902, Crater Lake is the fifth-oldest national park in the United States and the only national park in Oregon. The park encompasses the caldera of Crater Lake, a remnant of Mount Mazama, a destroyed volcano, and the surrounding hills and forests.

The lake is 1,949 feet (594 m) deep at its deepest point, which makes it the deepest lake in the United States, the second-deepest in North America and the tenth-deepest in the world. Crater Lake is often referred to as the seventh-deepest lake in the world, but this former listing excludes the approximately 3,000-foot (910 m) depth of subglacial Lake Vostok in Antarctica, which resides under nearly 13,000 feet (4,000 m) of ice, and the recent report of a 2,740-foot (840 m) maximum depth for Lake O'Higgins/San Martin, located on the border of Chile and Argentina. However, when comparing its average depth of 1,148 feet (350 m) to the average depth of other deep lakes, Crater Lake becomes the deepest in the Western Hemisphere and the third-deepest in the world.

The impressive average depth of this volcanic lake is due to the nearly symmetrical 4,000-foot-deep (1,200 m) caldera formed 7,700 years ago (about 8 kya) during the violent climactic eruptions and subsequent collapse of Mount Mazama and the relatively moist climate that is typical of the crest of the Cascade Range. The caldera rim ranges in elevation from 7,000 to 8,000 feet (2,100 to 2,400 m).

Crater Lake National Park occupies a particular place in the imagination of American public lands. As a National Park in Oregon, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.

What this guide covers

Over the next four pages, this field guide breaks Crater Lake National Park into the practical questions every traveler asks: which trails are worth the effort, where to sleep both inside and outside the park boundary, what else is worth a stop in the surrounding region, and the small-but-essential tips that make the difference between a stressful first day and a smooth one. Use the navigation above to jump between sections, or read them in order — they're written to flow.
