Crater Lake National Park

Log in to track your visit to Crater Lake National Park.

Crater Lake National Park in southern Oregon protects the deepest lake in the United States and one of the most intensely blue bodies of water on Earth. The lake was born approximately 7,700 years ago when Mount Mazama, a massive Cascade volcano, erupted so violently that it collapsed into its own magma chamber — an event witnessed by the ancestors of the Klamath people, who have preserved oral traditions describing the cataclysm. The resulting caldera slowly filled with rainwater and snowmelt over centuries, with no rivers flowing in or out. Because the water has never been in contact with soil minerals and receives no sediment, it achieves a purity and clarity that produces its extraordinary electric-blue color — the lake has an average visibility depth of 102 feet, and in calm conditions its surface appears almost artificially blue, like something painted by a digital artist. At 1,943 feet deep, it holds enough water to fill Lake Ontario. Crater Lake National Park was established in 1902 — Oregon's only national park — and covers 183,000 acres of volcanic landscape including meadows, old-growth forest, and the dramatic 33-mile Rim Drive circling the caldera's edge. Wizard Island, a small cinder cone volcano rising 763 feet above the lake's surface near the western shore, adds a layer of volcanic drama to an already extraordinary scene.

Rim Drive is the 33-mile paved road encircling the caldera with more than 30 overlooks — allow three to four hours to stop at all of them. Watchman Peak (1.6 miles round trip, 420 feet gain) climbs to a fire lookout on the rim with a panoramic view that encompasses the full lake and Wizard Island; it's one of the park's finest short hikes. The Cleetwood Cove Trail (2.2 miles round trip, 700-foot descent) is the only legal path down to the lake shore and connects to the Wizard Island boat tour — a concessionaire-operated shuttle that drops visitors on the island for hiking and fishing (book well in advance). Swimming in the lake is permitted and memorably cold — water temperatures hover around 38–50°F even in August. The Garfield Peak Trail (3.6 miles round trip, 1,000 feet gain) follows the rim to a summit with dramatic views of the Phantom Ship rock formation below. In winter, Crater Lake receives some of the highest annual snowfall in Oregon, transforming the park into a snowshoeing and cross-country skiing destination with marked trails from the visitor center.

Crater Lake's surface ecosystem supports rainbow trout and kokanee salmon, both introduced non-native species, that are sought by anglers who bring their own rods and obtain a free fishing license from the park (no license required for the lake, uniquely in Oregon). The surrounding old-growth Ponderosa pine and Shasta red fir forests harbor black bears, mule deer, elk, and pine martens. Clark's nutcrackers are the quintessential bird of the rim, caching seeds in crevices near the overlooks. Golden-mantled ground squirrels are boldly curious near visitor areas. Osprey and bald eagles hunt the lake surface.

Entry is $35 per vehicle (valid 7 days). The south entrance and Rim Village area are typically open year-round, but the North Entrance Road and most of Rim Drive close due to snow from mid-October through mid-July — sometimes later. Check road conditions before visiting in spring. Crater Lake Lodge, perched dramatically on the rim, is one of the great national park lodges; book 13 months in advance for summer dates. Mazama Village Campground (214 sites) is reservable; the smaller Lost Creek Campground is tent-only. The park's elevation (6,178 feet at the rim) means altitude adjustment is needed.

Crater Lake is in south-central Oregon, 80 miles north of Klamath Falls and 80 miles northeast of Medford via OR-62. From Portland, drive south on I-5 to Medford, then northeast on OR-62 — about 4.5 hours. From Eugene, OR-58 east connects to US-97 south and then OR-232 west — about 3.5 hours. Rogue Valley–Medford International (MFR) and Klamath Falls (LMT) are the nearest commercial airports. No public transit serves the park.

The Cleetwood Cove Trail hike down to the boat dock is strenuous — 700 feet of descent that must be re-climbed — and is not suitable for people with mobility limitations. Wizard Island boat tours sell out weeks in advance; book online as soon as you have your dates. The lake looks different in every light: overcast days produce a more moody, steely blue, while full sun turns it electric teal. Visit early morning for mirror-calm water and the best photography conditions. Snow can fall any month of the year at the rim elevation; always carry a layer.
