Overview
The Old Crater Trail in Winema National Forest provides access to one of the accessible volcanic features in the southern Cascades, a partially preserved cinder cone crater with obsidian deposits and views over the Klamath Basin. The Cascade Range is built entirely on volcanic activity, and the Old Crater provides a tangible connection to that ongoing geological story in a package accessible to day hikers without technical climbing.
The obsidian deposits along the crater rim are particularly interesting: black volcanic glass formed when silica-rich lava cooled too quickly to crystallize. Obsidian from the Cascades was prized by Native American cultures throughout the Pacific Northwest for its ability to hold an edge sharper than surgical steel, and trading in Cascade obsidian extended hundreds of miles from its sources.
The Route
The trail begins at the trailhead and climbs through lodgepole pine and mountain hemlock forest toward the crater. The forest opens as the trail approaches the cinder cone, providing views over the surrounding landscape. The crater rim circuit allows hikers to circle the preserved bowl before returning on the same route.
What to Expect
No water is available on the route. The volcanic terrain can be loose and unstable on the crater slopes; careful foot placement is required. Sharp obsidian pieces are present on the crater rim; wear sturdy boots. The views from the rim improve significantly on clear days when the Klamath Lake and distant ranges are visible.

Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
Safety Considerations
The moderate rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Winema National Forest and may be unreliable in canyon bottoms or remote terrain.
