Northern California Wilderness Areas: Marble Mountain & Trinity Alps

Trail Miles 709 Forests Involved Klamath National Forest, CA Six Rivers National Forest, CA Shasta-Trinity National Forest, CA

The Marble Mountain and Trinity Alps wilderness areas are located within the steep and mountainous terrain of the Klamath Mountains. Visitors access the expansive vistas, numerous lakes, and several Wild and Scenic Rivers within these wilderness areas through a network of over 980 miles of trails. Localized flooding and landslides from heavy rain and snow during the winter months typically damage a portion of the trail system each winter. These weather events and recent large wildfires in recent years have combined to create extensive areas of downed trees, dense brush, and damaged trail tread.

With the priority area focus, the Klamath, Shasta-Trinity, and Six Rivers National Forests are working with partners to develop and implement a sustainable trail maintenance program. Our goal is to maintain public access and opportunity to experience these wilderness areas as well as to sustain the vital local tourism economy.
