An excellent and challenging 3-day singletrack loop right out Portland's backdoor. Silver Siouxon connects a handful of southwest Washington's best MTB trails, remote backcountry riding, expansive views of cascade volcanoes, deep old growth forests, scree fields, and rugged ridge rambles.

One of the most frequent questions I hear is: “What can I bikepack on a long weekend that’s close to town?”

The Silver Siouxon route is the answer to that question. You get incredible backcountry singletrack and a remoteness that seems much, much farther than an hour’s drive from Portland. You’ll climb (errr, push) to above 4,000′, and traverse rocky ridgelines before descending through one of the most stunning old growth stands in the area.

Each day is approximately 25 miles, but don’t let that fool you — the steep pitches are unforgiving. There is plenty of water along the route, and a delicious hot meal waiting in Yacolt at the finish. The trails are steep and breathtaking, but only moderately technical. It’s close enough that with an extra day you could even pedal there from Portland’s city limits.

We rode it in October with stunning fall colors, but late spring and early summer sport an equally beautiful wildflower bloom. The variety of terrain you pass through is unique. Countless waterfalls, working timber forests, the faux-alpine terrain of Silver Star (a byproduct of the Yacolt Burn), the giant scree fields of Bluff Mountain, imposing Cougar Rock, and the verdant green tunnel of Siouxon Creek.

Difficulty: The majority of the route is excellent for intermediate bikepackers or mountain bikers and not particularly intimidating. But there are two factors making this a a somewhat challenging route — the steep ascent up Silver Star on day one and the exposure of Bluff Mountain on day two.

Route Development: The Tarbell Loop and Siouxon Creek trail have long been local destination days rides, and I’ve long explored the vast network of anonymous Gifford Pinchot forest roads for many years but on one of these adventures I noticed a faint shelf carved through a scree field in the distance off Silver Star and knew they all had to be connected.

Load up on Backwoods Diner’s loaded hashbrowns. You’ll need the calories. Then it’s a flat paved pedal, a few beautiful creeks, and a steep push up Bells Mountain before a fun, rolling trail to Tarbell Trail at Rock Creek Campground. Tarbell is a stiff climb for a few miles but then branching off on the Chinook Trail switchbacks you’re forced to a crawl. It’s soon worth it, though, as a picture perfect campsite rests on top of Silver Star with a hidden fresh water spring nearby.


You’ll probably wake to ambitious hikers huffing by for the summit, but you leave the throngs behind almost immediatly as you head east on Bluff Mountain trail. The exposure is gripping and the riding the most technical of the route as you traverse scree slopes with 360º views. Eventually you’ll connect with a series of little-used doubletrack roads that maintain elevation linking you north to Siouxon Creek. Siouxon is another popular trail but the upper trail is rarely accessed—which you drop into wrapping the day up in a glorious descent.


Your final day on the trail is a mellow one. A mostly flat cruise along Siouxon Creek brings you to a narrow paved road descent and another few miles back to your car… and those loaded hashbrowns.
