Dochgarroch Locks and Caledonian Canal (Inverness)
This very popular and almost level route follows the Caledonian Canal towpath from Inverness to the locks at Dochgarroch, returning on the far bank; there is usually plenty of activity on the water and on the route itself (runners and walkers).
The start is at Whin Park, Inverness with sufficient parking spaces.
