route description

The 4km green trail is a gentle circular trail that hugs the lakeshore and passes past under the shadow of Castlewellan Castle. The biking is very easy with only one slight gradient incline on the north side of the lake.

The 4.5km blue trail travels through woodland on singletrack with a number of rollers thrown in to make for a fun trail, perfect for those looking develop to their bike handling skills.

The 19km red trail enjoys the initial flowing singletrack and incredible views found on the blue trail before splitting off and ascending behind Castlewellan Castle and past a number of little known smaller lakes.

The fun then really begins when both the red and black options descend either side of Slievenaslat before sweeping back around to Cypress Pond.

There is a further black option 'Dolly's Chute' set to get your heart racing with 'Moorish Return' always a crowd pleaser for the homeward leg back to the trailhead.
