Trail Sections

Green Trail

Distance: 5km
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.

Blue Trail

Distance: 5km
This easy-going blue trail begins by running parallel to Castlewellan Lake on an elevated single-track trail with incredible panoramic views before re-joining the gentler green route back to the trailhead. The first half of this trail undulates through woodland on single-track 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

Distance: 20km
This fun red trail enjoys the initial flowing single-track 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 on the ‘White Water Rapide’ descent off Slievenaslat before sweeping back around to Cypress Pond, with ‘Moorish Return’ always a crowd pleaser for the homeward leg back to the trailhead.

Black Trail

Distance: 5km
This challenging black trail combination comes in two distinct trail sections, ‘Dolly’s Chute’ and the ‘Great Escarpe’, offering two great independent descents or an adventurous variation on the red trail. The biking offers a pleasant progression from the red, providing an extended opportunity on the red trail itself, or a gentle introduction to the next level of Mountain Biking.
