The Witch’s Trails are home to the World Cup mountain bike circuit on the slopes of Aonach Mor, next door to Ben Nevis and Fort William. The world cup events use a gruelling downhill course as well as a cross country route. For non-expert riders, there are plenty of alternatives, graded from black right through to blue. And it’s all free! Check out the website for a downloadable map, turn up at the Nevis Range car park, and have a great day’s biking in the forest.
