Circle of Discovery

Seven National Park Service sites in Southern Oregon and Northern California create "A Circle of Discovery"! These parks protect everything from America's tallest trees and its deepest lake to hydrothermal areas, marble caves, and dramatic waterfalls. Many fields of science span these parks and yet connect them, whether it be volcanism, astronomy, or hydrology.

No two parks are more than five hours of drive-time apart, but rugged mountain ranges and dense forests separated rich Native American histories and defined the cutural histories of each park. Animal and plant species may cross state and park boundaries but some are endemic to a specific location. And be prepared for a range of recreational opportunities.

Begin YOUR Tour

It does not matter which direction you drive, however the distances and times listed below will take you clockwise to seven parks beginning at Crater Lake and ending at Oregon Caves.

Crater Lake National Park
Begin YOUR Circle of Discovery Tour Here
A violent eruption triggered the inward collapse of Mount Mazama's summit. A mile deep basin was left behind collecting rain and snow, and eventually creating the deepest lake in the United States. It is one of the most pristine lakes on earth with an average clarity over 100 feet deep. Sheer cliffs encase the lake's immeasurable beauty, while diverse forests, meadows and streams expand across the remainder of Mount Mazama where the geologic story continues.

Lava Beds National Monument
~1½ hours/84 miles (135 km) from Crater Lake along the Circle of Discovery
Lava Beds National Monument is a land of turmoil, both geological and historical. Over the last half-million years, volcanic eruptions on the Medicine Lake shield volcano have created a rugged landscape dotted with diverse volcanic features. More than 700 caves, Native American rock art sites, historic battlefields and campsites, and a high desert wilderness experience await you!
