Popular around Harperrig Reservoir
This is a great bike section with a nice approach over the bridge and causeway of Threipmuir Reservoir that has great views over each side. Exponential Hill itself is a beautiful tree-lined avenue that is very scenic. The section itself is only 462 metres long but has a sharp 49 metres of height gain. A stunning place overall and a nice hill section to take in on the way to Bavelaw Castle.

Wilsontown, great information on this section regarding the history of the Town and it's close association with Iron production. The paths are easy going having been paved.

Pretty rough on a gravel bike. Just about ridable in wet weather (with plenty of hike-a-bike) with mud-capable tyres.

This is our favourite MTB loops for a quick spin from our factory gates - perfect for a lunchtime blast using Livingston's amazing off-road paths and a couple of cheeky bits of singletrack either side of the main Edinburgh to Glasgow motorway. Look out for UFO landing site memorial stone and take a trip up Dechmont Law for great views across town to the Pentlands.

Built in 1885 this viaduct once carried the single-track mineral railway which served the local industry. The railway closed in 1956 but walkers can cross or walk underneath to get a view of the 9 arches.
