A walk with my camera from Bulbourne along the Grand Union Canal to Marsworth Reservoir, and back. I used public transport, the no. 61 bus from Aylesbury to Dunstable. The nearest stop on the way there is just past Tring Garden Centre which will appear on your right, and is also the location of the return journey bus stop. It takes about 20/25 minutes from the Aylesbury bus station.
The first photo is looking back towards the road I left, just out of shot is the Grand Junction Arms.
