“Overlooks, views, and tunnels make this part of Historic Columbia River Highway State Trail great.”— Eric Ashley
From the stone guardrail you'll get you first glimpse of Eighteen Mile Island Below. Ahead, a stone-walled lookout on the edge of the gorge provides an even better view. In April and May the grassy area around the lookout brightens with several types of wildflowers including balsam root.
Directly beyond the lookout is the entrance to the east tunnel. The combined length of the tunnels is quite short and visibility remains good throughout. There are also a few side passages leading to windows know as adits. On the other end of the tunnels is a long structure to catch rocks. If you're looking for a shorter out-and-back option, the tunnels are a popular spot to turn around.
Beyond the tunnels the trail continues for about four miles until it reaches the Mark Hatfield West Trailhead and the visitor center there. This portion receives more moisture and is greener and has more trees as a result.
This content was contributed by the Friends of the Columbia Gorge. To find more runs they recommend and to learn about their efforts to support the Columbia Gorge click here.
In addition to the adits in the tunnel, you'll also milepost 72 and carved graffiti from 1921 that details the names of the party who was stranded in the tunnel during a snowstorm.
