The Lairig Ghru is the best known hill-pass in Scotland. It climbs to an altitude of 835 metres and crosses through the central Cairngorms, one of the wildest areas in the country, and is a true classic trail. It is described from Speyside to Deeside. The route passes a number of Munros and boasts stunning views as you climb above the virgin forest. The route is largely single track, but also has a km of boulder field. While there is a race that includes this route, there are parts of the race that are not included in the traditional trail.
