The most popular ascent of Ben Tee starts at the Laggan locks on the Caledonian Canal at grid reference where there is a car park. The minor road to Kilfinnan on the north side of Loch Lochy is taken and left about 200 metres before the Kilfinnan Burn is reached to strike north west up the steep slopes of Ben Tee. Do not take the path to the Kilfinnan Falls as it is not possible to exit the gorge further up, however the falls are worth visiting but steps will have to be retraced. The route continues across moorland which steepens to reach the broad eastern ridge and then the summit. Approaches are possible from the north and the east, one starts at the bridge over Loch Garry (grid reference ), while another starts at the Forestry Commission's Alt na Cailliche car park near Invergarry (grid reference ). Both these routes are longer than the Kilfinnan approach.
