Roydon Mill Marina sits on the River Stort Navigation near Roydon, offering one of the largest marina facilities on the waterway with around 315 berths.

It is accessed from the navigation via a dedicated lock and forms part of the broader Roydon Marina Village development, which combines the marina with a hotel, holiday chalets, a restaurant, a bar, and a caravan site.

The site is positioned close to Roydon Lock, where the historic three-storey mill building — constructed of yellow brick with a weatherboarded upper storey — still stands as a local landmark.

The surrounding area transitions into the Lee Valley Regional Park, making this a convenient and well-appointed stopping point for boaters cruising the Stort Navigation.
