We decided to wrap up our Valentine's weekend trip to Hood River by stretching our winter-weary hiking legs with a trip up to see the historic Twin Tunnels just west of Mosier, Oregon. Really more of a stroll than a hike, this short 1.1 mile jaunt (one way, from the Mosier-side trail-head) offers some fabulous views of the Columbia River Gorge.
Once an important link in the scenic Columbia River Highway, the Mosier Twin Tunnels were constructed between 1919 and 1921. From the beginning, the tunnels and the nearby cliffs presented a trouble spot on the historic highway: rockfalls were common and accidents happened frequently. Eventually abandoned in 1955 after the completion of Highway I-84, the tunnels were soon filled in with rubble and forgotten.
Then, in the 1980's, interest in restoring the old historic highway began to develop. In 1995, with help of longtime Oregon Senator Mark Hatfield, work was begun to reopen the tunnels for tourist use. Rubble was removed from inside the tunnels, the walls were rebuilt, and the road was completely resurfaced.
The twin tunnels were reopened in July 2000 for bicycle and foot traffic, and are now part of the 4.6-mile-long "Historic Columbia River Highway State Trail."
The hike itself is mostly flat, with just a slight elevation change, and paved, making it a smooth ride for cyclists and wheelchair hikers.
I don't know if it is always this way, but on the day we went, cyclists outnumbered walkers nealry two to one.
Hiking in from the Mosier side, the trail soon comes to the edge of the Gorge and turns west. Here, you’ll walk past stone guardrails and look down to a great view of Eighteen Mile Island, known locally as Chicken Charlie Island.
This 10-acre island, once owned by one Charles Reither, was significantly larger before the completion of Bonneville Dam in 1937, and was home to a chicken ranch and a small railroad. It is now the only privately owned island in the Columbia River Gorge.
Just over a half mile into the hike, a beautiful new stone-walled lookout has been built over the Columbia River, and a short distance past the lookout is the east portal of the east tunnel. The entrance to the Eastern Portal has been restored to very much the same as it was nearly 100 years ago (pavement and cement curbs notwithstanding).
The second tunnel has two windows, known as adits, looking out over the river. There are steps that once led to viewpoints, but these are now blocked to the public. They make for some cool images though.
Beyond the tunnels, the trail continues another 3.5 miles to the Mark O. Hatfield West Trailhead, near Hood River.
This hike was a beautiful way to end our weekend, and a great way to kick off the hiking season here in the Pacific Northwest. Hopefully we will see you on the trail soon!
Mark O. Hatfield East Trailhead: (Starting from the Mosier side - 1.1 miles to Twin Tunnels)
From I-84 take Exit 69/Mosier. Follow the Historic Columbia River Highway as it curves left toward the town of Mosier. At the base of the bridge, turn left and circle under the bridge. Drive approximately 1 mile to the trailhead parking lot, which is clearly marked on the left. The actual trailhead is about a football field away from the parking lot.
Mark O. Hatfield West Trailhead: (Starting from the Hood River side - 3.5 miles to Twin Tunnels)
From I-84 take Exit 64/Highway 35, White Salmon & Government Camp. After exiting, turn right at the stop sign and then make another right turn. Head up for 0.4 miles to a four-way intersection and turn left toward the Historic Highway State Park. Wind up the hill for 1.2 miles and turn left into the parking area at Mark O. Hatfield Western Trailhead.
