Our bike ride along the Monsal Trail to Hassop and back was a firm highlight of a family weekend away! Friendly and efficient service from the men at the hire shop, everything straightforward just a driving license left as a deposit. Would advise anyone just to be wary of dogs not on leads inside the long tunnels. Visibility poor and path becomes narrower. Even well behaved dogs may be unpredictable. Unfortunately my relative collided with one that moved into our path….however both dog and Auntie not badly injured!!!
