Castlewellan Forest Park, with green, blue and red grade trails (black options remain closed until further notice) is a must-visit for mountain bikers of all ages and abilities.

CURRENTLY CLOSED - GREEN TRAIL - 4km Green Trail - Allow 30 minutes 

This gentle circular trail 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.

This wide trail is ideal for young families and/or those giving mountain biking a go for the very first time. 

CURRENTLY CLOSED - BLUE TRAIL - 4.5km Blue Trail - Allow 45 minutes

This easy going blue trail begins by running parallel to Castlewellan Lake on an elevated singetrack trail with incredible panoramic views  before rejoining the gentler green route back to the trailhead.

The first half of this trail undulates 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. 

RED TRAIL - Red Trail: Between 12-43 open - proceed with care. Diversion in place at 43 - proceed to 62 and continue along fire road back to 12. Diversion in place from 12 to 46 following signs.  46 – 49 on red trail are open.  At 49 exit trails via Crow Road. 

19km Red Trail - Allow 2 hours

The 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.

CURRENTLY CLOSED - BLACK OPTION - DOLLY’S CHUTE - Distance of Dolly's Chute is 0.9 miles, route type is a loop and the terrain is forest, off public road (currently closed due to storm damage).

THE GREAT ESCAPE - Public roads: Off Public Road
Getting to the start: The Great Escarpe is reached via waypoint 31 off the red trail before White Water Rapide.

Traffic/Terrain: Visitors may encounter Forest Service vehicles or timber lorries along the trail. During the fishing season (March to November), anglers' cars may also be present. The trail follows well-maintained forest and mountain bike paths, ensuring a generally smooth and accessible route.
