This waterside walk takes you along the Aylesbury Arm of the Grand Union Canal. The arm runs for about 6 miles from Aylesbury to Marsworth. You can start off from the centre of town near the train station or there is a parking area on the outskirts next to the canal. You then head east along the towpath to the village of Marsworth. Along the way there are pretty locks, stone bridges over the water and some nice views of the surrounding Bucks countryside to enjoy. Near the end of the walk you'll pass the lovely Tring Reservoirs. If you have time it is well worth following the footpaths around the four reservoirs which include Startops End, Marsworth, Tringford and Wilstone reservoir. Look out for birds such as grebes and bitterns on the water.
Just before Wilstone you will pass the Aylesbury Ring long distance footpath which crosses the canal. You can pick this up to explore the Buckinghamshire countryside around Long Marston and Buckland.
At Marsworth you have the option of continuing along the Grand Union Canal. Heading north will take you towards Cheddington, while heading south east will take you past Tring towards Berkhamsted.
