Waterfront / CARDIFF

Cardiff Bay waterfront

Around Mermaid Quay and Roald Dahl Plass, Cardiff’s former dockland becomes a place for a short waterside walk. Look across the Bay, compare the red-brick Pierhead with the Senedd, and pause for food if it fits your budget. A compact waterfront visit pairs naturally with Techniquest or the Senedd.

Before you go

Keep the first walk around the central waterfront. Continuing to the Barrage turns a short pause into a much longer, exposed outing with a return journey to plan.
