Southwest of Dublin and southeast of Shannon, the Ballyhoura Trails Mountain Bike Centre provides access to numerous mountain bike loops totalling about 96km. It is considered the largest trail network in Ireland. There are steep climbs through dense forest, and rolling winding singletrack. The one-way loops are waymarked with color codes signs, and the loops are stacked such that one loop leads to the next.
The 17km Mountrussell Loop is a more technical and physically demanding version of the Greenwood Loop and follows this as far as Waypoint 1, from where the trails become a bit more technical, narrower, rockier and steeper with more climbing and more descending.

The Mountrussell Loop features some steep climbs on forest roads and singletrack as well as long singletrack descents. All of the singletrack trails have extremely varied and sometimes very uneven surfaces, including rocks, loose gravel, mud, water and roots and are often very narrow (not more than 1m wide) with lots of tight turns, encroaching vegetation and with trees and boulders very close to the trail. There are also long sections of elevated timber boardwalk with exposed edges and uneven and sometimes slippery surfaces.
Follow the Brown waymarkers all the way to Waypoint 3 where you begin the inward leg of the Loop and eventually pick up the Green waymarkers that lead you back to the car park. Along the way you will pass Waypoint 2 where you can take a shortcut back to the car park by going left up the hill to pick up the inward leg of the Loop.
Overall, Mountrussell Loop is the 14th most popular mountain bike trail of all 14 mountain biking rides in Ireland.
