This mountain biking mecca is situated very close to Enniskerry Village and Roundwood. To call this one a mountain is a little bit of a misnomer as most of it is in a valley. The very valley that the spectacular Powerscourt Waterfall falls into. The intrepid fatbike is not afraid of this particular terrain but be warned, it is not for the feint hearted so expect a lot of climbing, your rewards will however be plentiful as both the waterfall and the surrounding woods are peaceful and awe inspiring. Distance is 14-20km’s.
