While there can be nothing better than heading to a museum or gallery for indoor activities with the kids when the sun isn’t shining, sometimes the day demands a more energetic activity. Sports and activity centres offer rainy day activities that give the whole family the chance try a new activity together. How about indoor rock climbing or go-karting? For a slightly different thrill on a rainy day, explore an underground cave system, or the crypts, secret tunnels and dungeons that lie in wait under many castles. Or just pull up your hood, put on your wellies and head outside to splash in the puddles.
