Cardiff Marina sits on the River Ely (Afon Elái) within Cardiff Bay, offering safe, secure, and sheltered moorings for motor boats and yachts.

Its south-facing position provides easy, free-flowing access to the wider bay, while the Cardiff Bay Barrage gives onward passage to the Bristol Channel.

The marina is operated by Cardiff Marine Group, which also provides boat servicing, treatments, and repairs on site. The surrounding area is a vibrant urban waterfront, placing visiting mariners within easy reach of Cardiff city centre and its amenities.

The location blends the area's deep maritime heritage — Cardiff Bay was once among the world's busiest coal-exporting ports — with a thoroughly modern waterfront environment.
