Siouxan Trail is one of the most scenic easy trails around.
Unnamed Waterfall along the road to Siouxan Trailhead
It has waterfalls galore, bridges, lush foliage, trees, and follows the Siouxan Creek. The trail wanders along the creek and has ups and downs, but no extremes. I would put it into the easy category. Some of the side trail off the Siouxan Trail are very difficult – like the Horseshoe Ridge Trail.
This is a very popular trail during peak hiking season. It has several creek-side camp site all along the trail. Popular for backpacking and camping for several days. The Siouxan Creek has many different waterfalls – some named and some not. Pictured here are the ones you will find in the first 5 miles of this trail. The named ones are Horseshoe Creek Falls, Siouxan Falls, 14 Mile Falls. There are several that are either unnamed or I did not find the name for them. The Chinook Trail bridge is closed for repairs so any of the “loop” trails described on the Internet require wading the creek – something that would not be too smart this time of year.
The actual trail is easy to find and well marked. It is mostly dirt and tree needles. Some areas get muddy after a rain, and some areas are a little rocky – but not too bad. This is an out and back trail that is about 9 miles long. You can turn around at any point. Overall this is a great place to take a family hiking.
