Penarth Marina has changed immeasurably over the past 15 years from a small community into a thriving waterside development. With the construction of the Cardiff Bay barrage creating a freshwater lake, the marina offers spectacular views across the bay to Mermaid Quay, the heart of the Cardiff Bay development. A waterbus travels from Cardiff Bay across to the marina and is popular with tourists and residents alike. Why not take a walk along the barrage after strolling around the marina and learn about how the development has taken shape from its infancy to now?
