Sweeping views of the majestic Columbia River and basalt cliffs lead you to the Mosier Twin Tunnels, a stunning piece of engineering that has been restored. Located on the original Scenic Highway, which is now the Historic Columbia River Highway State Trail and is a car free zone, the trail offers those walking, jogging or cycling stunning views of the Columbia River, beautiful in every season.
The trail is 4.5 miles and connects Mosier in the east to Hood River in the west with parking lots on both ends. A State Parks Pass ( $5 ) is required and the views are more than worth it! A payment box and envelopes are provided, but make sure you have a pen to fill in the info. There are restrooms and they are the open toilet type, so this is not the time to drop your cellphone!
If you start in Mosier, park in Mark O. Hatfield Trailhead Lot East which is actually past the start of the trailhead. After paying for the pass, head right out of the lot and just a short distance down the hill on the left is the entrance. You will pass through an area filled with granite and lava rocks and many trees damaged by the fires - then you will continue up and the path will run high above and parallel to the river. Parts of the trail have the classic white fence railing and some parts have the original stone railings with arches giving glimpses of the view below.
Continue on the trail for approximately one mile and you will arrive at the tunnels. The first tunnel has an incredible wooden structure entry, it's magnificent! As you walk through, it becomes rock and very cavernous. There are a few side passages that lead to windows with views to 18 Mile Island and the river. You will then come to a rock catchment structure, added during restoration in the 1990s, and then the second tunnel.
Beyond the tunnels the trail continues west for another 3.4 miles. At the Mark O. Hatfield Parking West, where there is an interpretive center that provides more detail on the tunnels and the Historic Highway.
I was in awe of the views and couldn't stop taking pictures along the way! Since it's the end of March, the trees were not yet bloomed so the views of the river were mostly unobstructed. Wildflowers like the grass widow and dessert parsley were just starting to bloom. I'll be back in a few weeks when the trail will be filled with glorious flowers! Ponderosa pines are everywhere as are pinecones!
There is a viewpoint right before the East entry to the tunnels. It will only set you back 1/10 of a mile and it's totally worth walking to for a full 180 degree vantage point. There is even a picnic table nearby for resting or a lunch break.
These tunnels are a marvel! Built in 1921, the tunnels were created to get through a high rock point. The design was inspired by the Axenstrasse on Lake Lucerne in Switzerland. Although beautiful and a highlight for those driving this route, rockfalls were common and accidents frequent so the original Scenic Highway was abandoned in 1954 and a new Scenic Highway built at water level. By the 1990s, the tunnels were completely filled with rock rubble; in the mid 90s work began to restore the tunnels. It was a massive undertaking and now the tunnels and road has been transformed for everyone to enjoy.
The Mosier Tunnels are a must see! The trail is easy since it's paved - which is a requirement for me and my knees - so it's family friendly and a doable hike for most anyone. There is a gradual elevation to 430 feet if you start on the east side.
There is one handicapped parking spot right at the trailhead entry. Dogs on leashes are allowed. Bicycles and e-bikes but no motorized skateboards. If you are walking, be aware of the cyclists as they go fast when heading downhill to the east end.
After exploring the Mosier Twin Tunnels, drive down to the quaint town of Mosier and have a delicious tamale, taco or burrito at either of the two taco trucks. Stellar coffee and scones are a must at Randonnee Coffee. Casual dinner at MoCo (Mosier Company) at the outdoor picnic tables and fire pits is always a good choice. And take the short drive up to Rowena Crest for more iconic views! read more
