Mountain Biking Gibson Jack/west Fork

*****   Add a review
#33 of 316 mountain bike trails in Idaho
#3,074 in the world

The West Fork is a mix of single/doubletrack with some fun rock spots and good scenery throughout. After climbing about 1500' in elevation, it's all downhill on singletrack on the Gibson Jack trail. The singletrack isn't always the best, but the scenery is fantastic. You can make a loop by riding about 7 miles of highway and 2 miles of secondary road. If you don't want to do the road, you can go to either trailhead and do an out and back--climb as far as you want and bomb back down. This ride is better than the description makes it sound.

    I have ridden this trail many times. If you are not careful, it will get you. Some difficult sections, rocky and a long climb. Beautiful trail.

    I am relatively new to mountain biking, but my wife and I enjoyed this ride. It is one of my first experiences with single track. Some parts of the trail are narrow and deep, but it was a lot of fun.
