This 4.5 mile circular walk starts and finishes in Wilstone village, two miles northwest of Tring.
The route takes in all four reservoirs, the Grand Union canal and its Wendover and Aylesbury arms. For those not wanting to walk this far, there are numerous options in the area for shorter walks.
Much of the route has a good surface along reservoir banks and canal towpaths, but some sections can become muddy after wet weather and in the winter. As well as a long flight of steps up to Wilstone reservoir there are steps in other places along the route.
