Siouxon Creek Trail is one of the best trails for mountain biking in the northwest. It has incredible flowy singletrack, ripping descents, challenging rocky areas, creek crossings, and some of the most beautiful waterfalls and clear pools around, period. Adding in the climb to Siouxon and Huffman Peaks makes this brutally hard, but it adds incredible views of Mt St Helens, Mt. Rainier, Mt. Adams, and Mt. Hood and also gives riders a killer 7.0 mile descent.


The ride starts at the upper Siouxon Trailhead just past the hairpin off road 5701. At 1.2 miles, you'll see the Huffman Peak #129 come in from the left (part of the return leg), but continue straight on Siouxon Trail. At 3.2 miles, you'll come to the official Siouxon Trailhead where all the hikers start from. If you're going to see any hikers its going to be in the next 4.2 miles, so use caution and be very courteous.

At 7.4 miles, there is a bridge to the left that crosses Siouxon Creek. Take the bridge to the left to start up Chinook Creek #130A. After 0.25 miles, the trail drops down to the creek at Chinook Falls. There is a log you can cross on that takes you directly to the trail on the other side.

Continue past the creek a quarter mile to a trail intersection at mile 7.9. Make a sharp right at the trail intersection to stay on Trail #130A. This is where the climbing begins. At mile 11, you intersect with road 6403. Take a left on the road and it almost immediately turns back into trail and begins climbing towards Siouxon Peak.

Once youve reached Siouxon Peak at mile 13.3, the trail is mostly downhill until you get to Siouxon Creek. It drops 3,000 over the next 7.0 miles. You'll pass the top of Wildcat #156, that goes to the left at around mile 14.5. Do not take this as it will take you back down close to Chinook Falls. The next trail intersection you get to is at mile 16.1 and you want to go left to stay on the Huffman Peak #129. Keep descending for about 4.0 miles until you get to Siouxon Creek.

Cross the creek to the trail on the other side. Take the trail about up 0.3 mile to Lower Siouxon #130D, where a turn to the right leads to the final 1.2 miles back to the finish.

Bring your climbing (and hiking) legs. Unless you're a complete monster, plan on bit of hiking. Awesome ride either way. — 5h 30m

Trail was in very good shape. A lot of recent clearing of downed logs. Some of the ups are crazy steep. Bring your climbing legs & low gears. — 5h 18m

11/28/15 Trail Report: Tread was in great shape, no mud and only a few down trees. Awesome trail that has beautiful views around every corner. Highly recommend this trail even if the drive there is not so great. Get out there and ride this trail before the snow comes! Nov 29, 2015
It's two very different rides: Siouxon is a lovely beginner to intermediate out-and-back trail with modest climbing either out or back. Start near the sharp bend before the road descends to the parking lot - that adds a fun moderate hill to the ride. Huffman is an add-on loop that has a steep and aerobically tough climb and a steep descent. Some short sideslope and narrow sections near the top, but mostly not technical, just difficult for steepness of climb and (less so) descent. It requires crossing Siouxon creek as part of the loop, which is generally not an issue but challenging during high water conditions. Feb 27, 2018
