Grand Union Canal: Marsworth to Tring Reservoirs
Buckinghamshire
This 8.6 km circular from Marsworth traces the Grand Union Canal towpath past the Marsworth flight of locks before opening out around four reservoirs — Startops End, Marsworth, Tringford and Wilstone — all managed as Sites of Special Scientific Interest and important bird reserves. The route is flat, well-surfaced and reliable in all weathers, shifting between the intimate feel of the canal corridor and the wider, open landscape around the reservoirs. Reed beds, open water and willow-lined banks create a rich wetland atmosphere that changes character with each reservoir you pass.
This is one of the best easy dog friendly walks in Buckinghamshire. The canal offers constant water access for drinking and paddling, and the reservoir margins add variety with their reed-fringed edges and waterfowl activity. Off-lead potential is low given the sensitive bird habitats around the reservoirs, so reliable recall or a long lead is recommended. Livestock risk is low throughout, and the flat, well-surfaced paths suit dogs of all ages and fitness levels. Dog-friendly pubs near Marsworth provide a comfortable post-walk stop.
