Columbia River Gorge NSA Mosier Tunnel Hike Hike 63 Length: 9 miles round trip Elevation Change: 300 feet Season:   Late winter thru late fall Difficulty:   Moderate Permit:   NW Forest Pass Required Features: I call this the Moiser Tunnel hike, but most refer to it as the Historic Columbia River State Trail. A project that was completed in 2000 to restore a portion of the old Columbia River highway to its original condition between Hood River and Mosier. Today, hikers and bike riders enjoy this unique paved trail most anytime during the year. Winter conditions can make the trail impassable. One can start at either end of this 4.5 mile trail. I consider beginning at the east end the better option in that you only need to hike about .75 miles to come to the tunnel system for which the entire hike is famous. I recommend hiking only half way along this road, unless you have shuttle sytem in place to pick you up at the other end. There is really no great reward in hiking the entire 4.5 miles from one end to the other, only to have to retrace the 4.5 miles back to your vehicle. This hike is unique. It is certain worth doing. And the reward is not only the very unique tunnel system, but the incredible views of the Columbia River Gorge and in season the wonderful foral displays. It is easy enough for the very young and/or the elderly. A Virtual Hike in the Columbia River Gorge NSA All for the love of hiking!
