About this landmark
Three Sisters Wilderness is a striking wilderness area located near Blue River in Oregon's Cascade Range. The region is named after the Three Sisters volcanic peaks, which rise prominently above the surrounding forested landscape and are among Oregon’s most iconic natural landmarks. These volcanic summits, composed of andesite and basalt, offer a dramatic contrast with the dense evergreen forests and lava flows seen in the lower elevations. The area's rugged terrain includes old lava beds, alpine meadows, and clear mountain lakes, creating a diverse environment for outdoor enthusiasts. One of the wilderness’s most unique geological features is the presence of extensive lava fields formed from past volcanic eruptions, which give the landscape a stark, otherworldly character. The wilderness was established in 1964 to protect this vast, pristine mountain area, which preserves important habitats for native wildlife and rare plant communities, including subalpine fir and mountain hemlock. Beyond its natural beauty, the region holds significance for local Native American tribes, who have historical and cultural connections to these lands. This wilderness attracts visitors year-round for its scenic beauty and opportunities to experience nature’s raw power and tranquility at the same time, making it a standout destination in Oregon’s vast outdoors.
