Techniquest

Cardiff Bay's premier science discovery centre featuring over 120 hands-on exhibits, a planetarium, and science theatre. This interactive museum makes science accessible and fun for all ages, from toddlers to adults, with regularly changing exhibitions and live demonstrations. It ranks among Cardiff's most visited sights, and for good reason - most itineraries include it on day one. Tickets cost £11.95 adult, £9.95 child, family tickets available and 2-4 hours is enough to see everything without rushing.

Priority: High - do not skip Time needed: 2-4 hours Best for: perfect rainy day activity Skip if: You're not interested in science or don't have children Cost: £11.95 adult, £9.95 child, family tickets available

You'll touch, press, pull, and experiment your way through floors of interactive exhibits. The planetarium show takes you on a journey through space, while live experiments happen throughout the day.

Accessibility: Fully wheelchair accessible with lifts to all floors. Audio guides and tactile exhibits available

Perfect rainy day activity that entertains and educates the whole family. That puts it near the top of any Cardiff visit, and it deserves the spot. Combine it with Wales Millennium Centre and Cardiff Bay Barrage - they are close enough to walk between and together make the strongest half-day in Cardiff. Mornings are quieter if you want to take your time.

Skip if: You're not interested in science or don't have children

• Book planetarium shows in advance as they often sell out.
• Bring hand sanitizer as exhibits are very hands-on.
• Check the daily demonstration schedule on arrival.
