Portage Route Trail

The first half of the trail is wide and mostly gravel, passing through two tunnels. The first is a small corrugated tunnel under the I-82, and the second is an old train tunnel through basalt rock roughly 100 yards in length. The tunnel’s end is visible upon entry, but it is quite dark so bring a source of light.

Wildlife Awareness
We are all so fortunate to recreate in the Blue Mountains and Walla Walla Valley. So many opportunities exist to play outside, whether in a national forest, wilderness area, or on a Wild and Scenic River. With these opportunities comes great responsibility to appreciate that we are mere visitors and should all take pride in being good stewards of the wild.

Many animals call these protected places home, including moose, elk, bear, cougar, bobcat, and snakes to name a few. Take precautions to respect their home and understand the appropriate response should an encounter occur.

Additionally, many plant species thrive in the Blue Mountains, so staying on trail is always good practice.

Carry First Aid supplies to better respond to accidents or encounters, and always let others know where the day’s adventure is taking you.

Field Notes
Pets: In general, pets are allowed on a leash and under control throughout jurisdictions. The only restrictions we have encountered are around swimming areas. As a best practice, be mindful of riparian habitat in general. You never know where a precious spawning area might be located. Pack it in and pack it out applies to your furry friend as well.
