ThingsToDoScience and a short Cardiff Bay walk
A manageable Bay half-day anchored by booked Techniquest entry. Travel to the Bay separately and confirm the return before starting; estimates below cover time on site.
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.
The practical details
