A stunning mix of history and scenery along the Columbia River (2015)

Historic Columbia River Highway State Trail — Mosier Twin Tunnels


Hikers on this year’s First Day Hike learned about the history of the Twin Tunnels and the Historic Columbia River Highway State Trail.

With its cliff-hugging curves and majestic views, Highway 30 was once ranked among the grandest highways in the nation during a time when a leisurely drive was the destination. The opening of Interstate 84 marked the end of that era, and Highway 30 is now closed to vehicle traffic—and open to explorers. A 5-mile stretch of the Historic Columbia River State Trail between Mosier and Hood River allows hikers and bicyclists to retrace the route once traversed by Ford Model A’s and Model T’s.

This paved section between Mosier and Hood River is perfect for a winter hike — and if timed just right, you can enjoy it on snowshoes or cross-country skis. The reward: panoramas of the mighty Columbia River Gorge, majestic basalt formations rising above you, hustle of traveling goods and people far below on the interstate and railroad.

But the highlight is most certainly the Mosier Twin Tunnels, built in 1921 through a high rock area, then abandoned and filled with rock in 1954 when I-84 was built. The state restored and reopened the tunnels to visitors in 2004. Within, look for milepost 72 of the historic highway, as well as carved graffiti from 1921 with the names of people who were trapped in the tunnel during a snowstorm. You’ll marvel at the ingenuity of the engineering and the curious way the tunnels separate two climate zones: the arid east gorge and the wetter west.

Be sure to stop in the visitor center at the Mark O. Hatfield West trailhead in Hood River for historical information on Highway 30, including original engineering blueprints. This winter the visitor center is open Saturdays and Sundays 10 a.m.-2 p.m.
