Suggested Itinerary

Day One (26.8 miles, 5,600 feet of elevbation gain) - From Yacolt, pedal on pavement, and then ride steeply up Bells Mountain before reaching Tarbell Trail at Rock Creek Campground. Tarbell Trail climbs for a few miles then branches off on the Chinook Trail switchbacks. The recommended campsite rests on top of Silver Star. There is a fresh water spring nearby.

Day Two (26.4 miles, 2,709 feet of elevation gain) - Head east on Bluff Mountain trail. The riding is the most technical of the route as you traverse scree slopes with panoramic views. You’ll then connect with a series of doubletrack roads that maintain elevation and link you to Siouxon Creek. Day two ends with a descent to Siouxon Creek Falls campsite. 

Day Three (21.8 miles, 1,559 feet of elevation gain) - Ride along Siouxon Creek to a narrow paved descent, and finally the return to Yacolt.
