Mark O. Hatfield West Trailhead Visitors CenterOn the Mt. Hood Loop Trail, a part of the Oregon Cascades Birding Trail. |
Located between Hood River and Mosier, the five mile Twin Tunnels - Hood River segment of the Historic Columbia River Highway State Trail passes through two climate zones. Starting at the east Mark O. Hatfield Trailhead Visitors Center 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.
