Where motorists on old U.S. Highway 30 once crept around curves high along the cliffs of the Columbia River Gorge, hikers, bicyclists and users of other muscle-driven forms of transportation leisurely enjoy the view from the Historic Columbia River Highway State Trail. The trail, two disconnected paved ribbons along abandoned stretches of the historic highway, give you more than 10 miles of sightseeing thrills.

Between Hood River and Mosier, the five mile Twin Tunnels segment passes through two climate zones. Starting at the east Mark O. Hatfield Trailhead near Mosier, the trail leads through semi-arid terrain dotted with ponderosa pine for about a mile until you reach the Twin Tunnels. Spectacular geologic formations tell the story of the gorge’s creation.

After passing through the tunnels, you’ll emerge into a forest of fir trees and other common western Oregon plants. Viewpoints along the 3.5 mile segment from the tunnels to the west Mark O. Hatfield Trailhead overlook the river.
