Cardiff Bay

Getting around: About 2 miles south of central Cardiff, reachable by the Cardiff Bay train line from Cardiff Queen Street (about 10 minutes), bus, or a pleasant 30-40 minute walk along the Taff Trail.
Hours: Open access at all times as a waterfront area; individual attractions (Wales Millennium Centre, Doctor Who Experience-adjacent sites, Senedd) keep their own separate hours.

Cardiff Bay is the redeveloped waterfront area around a former industrial dock, now home to the Welsh Parliament (Senedd), the Wales Millennium Centre, and a mix of restaurants, bars, and family attractions around the water. It was transformed from Cardiff's old coal-exporting docklands (once the busiest coal port in the world) into a leisure and civic district over the past few decades.

The Senedd building offers free public viewing of Wales's devolved parliament in session, and the bay itself is pleasant for a waterside walk, with a barrage that created the current freshwater lake from what was previously a tidal estuary. It's also a popular spot for family activities, water sports, and evening dining, particularly around the Mermaid Quay development.

A couple of hours covers a walk around the bay and a look at the Senedd and Wales Millennium Centre exteriors; longer if attending a show or event.
