Ben Wyvis is usually climbed from the west, starting just south of Garbat on the A835 road, where there is a car park maintained by Forestry and Land Scotland. The path follows the north bank of the Allt á Bhealaich Mhòir through the forest, before entering the NNR. From here the route ascends more steeply to reach An Cabar, the southernmost of the summits that lie along the main ridge. An alternative route, also accessed from the car park, takes in the Top of Tom a' Choinnich, which lies to the north of the main summit: the two routes can be combined to make a circular route.
