With close proximity to Proxy Falls, Linton Lake might be easily overlooked, but if you find yourself in the area, it's definitely worth the short hike out to the lake. With beautiful views, old-growth forests, and ancient lava flows, the hike has many interesting sights and is great on a hot summer or fall day. As the trailhead sign suggests, "Savor the solitude. Embrace this opportunity for self-discovery and primitive recreation."
The there-and-back trail starts across the road from the Alder Springs Campground and wanders through old-growth forests and old lava flows. The main trail ends where Obsidian Creek flows into the lake, but there are many unmaintained trails around the surrounding area. Be careful when exploring around the lava flows as the rocks can be unstable and easily shift underfoot. There is a waterfall upstream, but it is not visible from the lake.
Backcountry campsites can be found around the lake and make for a nice overnight trip in the Three Sisters Wilderness. Sites include fire rings.
Highway 242 leading to the trailhead is closed November through June. Parking at the trailhead is limited.
