I walked down Vicarage Lane to Hoo Marina and joined the clearly signed Saxon Shore Way path that runs along the River Medway to Kingsnorth. Soon after joining the path, you come across excellent views of Hoo Fort and Darnet Fort (in the middle of the River Medway). There are three WW2 pillboxes during the walk - an indication of how strategically important the area once was.
Altogether very enjoyable and a good mix of sights!
