Techniquest — a "science playground" on the Cardiff Bay waterfront: born in 1986 as the UK's first purpose-built interactive science discovery centre, welcoming over 7 million visitors in 40 years. Over 130 hands-on exhibits span five major themes — Space, Environment, Chemistry, Biomedical Science and World Issues — from launching rockets and virtual surgery to experiencing hurricane-force winds and earthquakes. Science is no longer dry textbook formulas but wonders you can touch with your own hands. Flame and liquid nitrogen explosion experiments in the Science Theatre, 360° dome planetarium star journeys, and KLA Lab slime workshops let visitors from age 3 to 93 discover the magic of science through laughter.
From space exploration to hurricane simulation, from Bernoulli blowers to giant pianos — unlock the full joy of science with your own hands in a single day
Start your morning at Cardiff Central Station, take the Baycar Route 6 bus direct to Cardiff Bay (about 8 minutes), then walk 5 minutes to Techniquest on Stuart Street. Upon entry, collect your xTag interactive tag — it records your exploration data throughout the day. Begin on the ground floor with "Science Capital," traversing five themed zones: Space, Environment, Chemistry, Biomedical Science and World Issues — launch a rocket with your own hands, operate a virtual surgery table, feel the force of a Category 8 hurricane, and use a Bernoulli blower to make a ball float in mid-air. Head upstairs to "Create & Shape" — build structures with cardboard, fold origami cranes, play with Spirograph spirographs. Grab a light lunch at Coffee Mania café, then watch the Battle of the Bangs explosive show in the Science Theatre, followed by a star journey in the 360° Planetarium. Don't miss the Sensory Garden on the East Terrace to smell herbs and touch succulents, then finish with a stroll along the Cardiff Bay waterfront, bringing a whole day of scientific memories back to reality.
The official café inside Techniquest, serving locally sourced drinks, sandwiches, hot meals and snacks. Cappuccino, selected teas and handmade cakes provide the most convenient refuelling stop after a morning of exploring science. Eat in or take away — families with children can relax by the window overlooking the bay. Budget: £5-10 per person.
A 5-minute walk to Mermaid Quay, this French brasserie chain maintains independent restaurant quality. Classic French onion soup, Boeuf Bourguignon, Steak Frites and chocolate fondant form the signature combination. Professional service and warm atmosphere, with window seats facing Roald Dahl Plass and the bay waters. A proper meal just minutes from the science centre. Budget: £20-35 per person.
A vibrant Latin American restaurant on the Mermaid Quay waterfront, with bright colours and lively atmosphere — an excellent choice for families with children. Brazilian grilled meats, Mexican tacos, Peruvian grilled chicken and house cocktails (2-for-1 happy hour) make up a varied menu, with thoughtful and delicious children's meals. Outdoor seating facing the water makes it one of Cardiff Bay's most cheerful lunch spots. Budget: £12-20 per person.
A waterfront bar and restaurant adjacent to the Wales Millennium Centre, with floor-to-ceiling windows facing Cardiff Bay waters — golden sunset light floods the tables at dusk. Specialising in contemporary British cuisine: fish and chips, Welsh lamb pie, seafood platter and Sunday Roast are signatures. Large glasses of red wine and sharing cocktails are perfect for whiling away an afternoon, just 4 minutes' walk from Techniquest. Budget: £15-25 per person.
