HERE’S a hand-picked guide to some of the most child-friendly visitor attractions and activities to be found in south Wales, but of course there is so much more to see and do.

Every activity carries helpful quick-glance themes; for example: Castles · Trains · Animals · Beaches · Nature · Rainy-day · Free entry · Outdoorsy. We also advise on the ideal age range for each attraction, the best time of year to visit and approximately how much time to allow (eg, 1-2 hours, half day, full day).
