Maunsell Fort Experience (Departing Queenborough)

Experience an unforgettable cruise from Queenborough into the wide open waters of the Thames Estuary, journeying beyond the familiar Red Sands Towers to explore the haunting silhouettes of the Shivering Sands Towers and the solitary Knock John Tower. This remarkable adventure takes you deep into wartime history, where these striking sea forts rise dramatically from the water as powerful reminders of Britain’s coastal defence during the Second World War.

Discover the stories behind these offshore fortifications as you sail past the wreck of the SS Richard Montgomery and the historic Kent Boom, crossing busy shipping channels toward the towering structures designed by Guy Maunsell. With time to circle each fort from a safe distance, you can capture exceptional photographs while your guide shares epic tales of wartime strategy, abandoned defences, and the enduring legacy of these extraordinary monuments standing miles from the Kent coastline.
