The Callendar Estate Mountain Bike Trails, including Greenrig Bike Park, are located just outside Falkirk and are owned by the Callendar Estate. The site offers four trails, each named after the woodland they pass through. The trail network includes blue and red graded climbs and descents, a red jump trail, and a beginner skills area. The trails feature Freestyle Velo wooden elements, adding variety and challenge. The range spans from a family-friendly green loop to a more technically demanding red route with optional orange (expert) features. Greenrig Bike Park, also on the estate, provides additional jumps and features for more advanced riders.
