Mountain Biking Manmade Falls

***   Add a review
#200 of 301 mountain bike trails in Idaho
#9,634 in the world

Starts off tame, and then drops like mad. Way steep downhill of a rock face leading to a waterfall
at the bottom (it's down there, believe me). If you take the juncture to the left before the
waterfall, a long green singletrack weaves beside the riverbank and back up to the main road
you drove in on. Don't get lost.

Getting there
From Rexburg, take Poleline road out until you reach a T (or can no longer go straight as it were), and take a left. Take that road until you reach another T, and take a right. On your left, there will be a dirt road going off into the field on your left. Take that road, and follow it as it curves to the right. Don't stop at the fence. The road snakes up to the right and then switchbacks to the left. At the top of that hill, there will be space for parking on the right, and the trailhead goes out from there.

    This is an amazing trail, but... Be careful of the directions you take. They say to take the trail under the power lines but a better trail with better downhill and less up down is just before the trail head at the bottom of the hill. There's a cabin and to the right of it is a trail that will take you to the falls and then just hang a right at the bottom of the hill and follow it on. That same trail is the best for going back up. It'sqquite a climb but totally worth it.

    I should add that the actual name of this destination is Webster's Dam. I hope that makes it a little more find-able.

    This is freerider territory, and I am not a freerider. I walked down this rockface, and then squealed my brakes a lot of the way. Too steep for me.
