The marina occupies the basin of the historic South Dock, completed in 1859 to facilitate coal exports.
The lock gate system is necessary to counteract one of the highest tidal ranges in the world, which can exceed 8 meters.
Swansea Marina operates under the management of the local authority rather than a private commercial operator.
The site includes a dedicated slipway for launching small craft and personal watercraft.
The marina basin remains connected to the River Tawe via the Tawe Barrage, which helps regulate water levels in the lower river corridor.
A series of residential blocks surrounding the marina were designed to integrate maritime heritage with modern urban living.
Swansea Marina is a 550-berth facility located within the redeveloped Maritime Quarter of Swansea, serving as a hub for both permanent and visitor vessels. The marina is accessed from the Bristol Channel via a lock system that maintains stable water levels regardless of the high tidal range of the Swansea Bay. It is situated on the site of the former South Dock, which was once a significant part of Swansea's industrial port operations. The area is now surrounded by residential apartments, restaurants, and the National Waterfront Museum. A swing bridge connects the marina to the Trawler Race quay and provides pedestrian access to the beach. The marina holds the Blue Flag award for its environmental standards and water quality. It functions as a central gateway for leisure craft cruising the South Wales coastline.

Walk the perimeter path connecting the marina to the Tawe Barrage for views of both the basin and the open bay.
Check the local tide tables if you plan to observe vessel movements through the lock, as these are dependent on sea levels.
Visit the adjacent National Waterfront Museum to learn about the industrial history of the docklands.
Do not attempt to walk onto private boarding pontoons, which are restricted to berth holders for security reasons.
Lock operations are subject to tidal constraints and may be restricted during extreme weather; contact the marina office for specific vessel transit windows.
