Columbia River Gorge NSA Tunnel Falls Hike Hike 37 Length: 12.0 miles round trip Elevation Change: 1050' gain Season: Year Round Difficulty:    Challenging due to length of hike Permit:   NW Forest Pass Required Features:   This is one of the most popular hikes in Oregon. After leaving the trail head, the hike almost immediately begins to climb the sheer rock walls of Eagle Creek. The builders placed cables to hold on to as the trail takes you past several very steep areas. At 2 miles you will come to Punchbowl Falls, and at 3.2 miles you will reach the High Bridge. After crossing the High Bridge, the trail continues upstream for another 2.8 miles to the fantastic Tunnel Falls. So names because the trail builders decided to carve a tunnel out of the sheer rock wall, over which the falls descends, for hikers to pass by the falls. But there's more. If you walk a short distance past Tunnel Falls, you come to another treat, falls on Eagle Creek itself. A Virtual Hike in the Columbia River Gorge NSA All for the love of hiking!
