Good trail though hard work in places.
An alternative to the tough bits is to follow the aqueduct beyond the dam "past the Aztec ruins and the ghosts of our people" to NN210613 and take the (steep!) trail which joins on with the fast, flowy lower section of the Ciaran Path.
A loop which starts and finishes at Altnafeadh and takes in the dam, aqueduct, CP lower section, Kinlochleven, Devil's Staircase climb(99% rideable on the return...) and Devil's Staircase descent back to Altnafeadh is a quality day out.
