Great Basalt Wall National Park protects one of the longest and most spectacular basalt rock formations in North America, offering dramatic landscapes and diverse recreational opportunities centered around lava fields and rugged cliffs.
Great Basalt Wall National Park is located in eastern Oregon and showcases an extraordinary volcanic landscape dominated by the Great Basalt Wall—a towering basalt cliff formed from ancient lava flows dating back over 15 million years. The park stretches across a large volcanic plateau featuring rocky outcrops, expansive lava fields, and unique geological formations. Ecologically, it supports sagebrush steppe habitat interspersed with pockets of juniper woodlands and rare desert wildflowers. Wildlife such as mule deer, pronghorns, golden eagles, and a variety of reptiles inhabit the area. Historically, this region has significance for Native American tribes who used its natural features for navigation and gathering. Outdoor enthusiasts visit the park for hiking along trails that trace the edge of the basalt cliffs with panoramic views, wildlife watching, rock climbing, and photography. The Great Basalt Wall itself is a prime attraction, rising hundreds of feet and extending for miles, providing dramatic scenery and geological interest. Various overlooks and trailheads allow visitors to experience the rugged beauty of the terrain. The park’s vast, open landscapes offer solitude and chances to observe night skies with little light pollution. It also serves as a natural laboratory to understand volcanic processes and erosion. Managed for both preservation and recreation, Great Basalt Wall National Park appeals to geologists, hikers, climbers, photographers, and nature lovers seeking a distinctive volcanic environment.
