I reviewed these notes in September 2022. The yacht Club and Marina set ups continue to thrive but as far as Mermaid Quay is concerned you get the less services than you would in a motorway services car park - except that you have to pay to park.

I reviewed these notes in September 2021. There appears to be a new RYA Sailing School on the East wall of the Bay but no facilities there for visitors.

Penarth Portway

Penarth Quays Marina has without doubt the best all round facilities in the Cardiff Bay area, with no problems living aboard for extended periods either. We also have the very well regarded Pier64 restaurant & Tesco is very close nearby as well.

The notes for Cardiff Bay were updated by Don T on the 15th February 2013. They have come a long way since nineties when the only option here was Penarth Marina. The choices of where to park your boat are good, the facilities at the marinas excellent and, compared to the South Coast, reasonably priced (those shown are those for the 2013 season). The problem is the remoteness of the marinas (the fact that Penarth Marina does bike hire should give you a clue) and you should be prepared to spend on taxis.
