Hampstead Marina, known as "The Island," sits on the non-tidal River Medway between Maidstone and Tonbridge in Kent. Regarded as one of the prettiest marinas in the south of England, it offers secure mooring for up to 160 craft in a tranquil setting.

On-site facilities include a boat hoist, hard standing, a marine engineering workshop, WC and shower block, car parking, and a trailer park. Entry is controlled by a code-operated gate and barrier, with 24-hour access for berth holders.

The marina is located on the port side by Hampstead Lock and features pontoon moorings and a cranage facility.

It lies close to the mainline station at Yalding and is approximately five miles from Junction 4 of the M20, making it accessible by both road and rail. A slipway and canoe platform adjacent to the lock also provide launching options for smaller craft.
