As at May 2026 normal exit at south end is closed by building work, exit easy to find when traveling south, not so easy when going north.

The Barrage connects Penarth to the Cardiff peninsula. It offers stunning views across the sea to one side, and the freshwater bay on the other. One of the highlights of the Cardiff Bay tour

Each lock is crossed by a Bascule bridge, to carry pedestrians and vehicles across. These are lifted for boats to pass. The weight of the bridge deck is counterbalanced by an overhead weight on the opposite side of the pivot. Five sluice gates control the level of water in the Bay. Each sluice gate is 9 metres wide and 7.5 metres high. The sluices open to maintain the level of the Bay, and close when the estuary level is higher than the Bay to prevent seawater entering the freshwater lake.
