Portland, OR: Dublin Lake via Tanner Butte Trail

A steady climb past towering firs and a cascading waterfall leads to Dublin Lake–the hidden gem of the Columbia River Gorge–on this 13.3-mile out-and-back.

Trip Tools

Start from the Wahclella Falls parking lot and hike north 100 yards to connect with the trailhead—if time permits, take the 1-mile side trip to Wahclella Falls. The first 4.5 miles of this trip switchback up the mountain, gaining 2,600 feet of elevation. The route passes enormous transmission towers (which connect to Bonneville Dam) before turning onto the Tanner Butte Trail. (Towering fir trees, a cascading waterfall, and trickling streams flank the trail.) After 4.7 miles, crest the Tanner Butte ridgeline, then climb 1.6 miles more to the junction with Dublin Lake Trail. From here, it’s a quick, 0.2-mile descent to Dublin Lake, a small, secluded lake rimmed by conifers and a few primitive campsites. On hot summer days, cool down with a refreshing dip before returning to the trailhead.
