We are staying South of Cambridge in the summer holidays. I would like recommendations of active days out nearby (ideally up to 45 mins drive). DC are 9 & 6. 9yo likes being active e.g. swimming, adventure playgrounds etc and will moan if we are 'just' walking. 6yo easier to please and particularly enjoys digging in the sand, swimming. I would prefer outdoor places rather than indoor climbing walls etc although useful to have a mixture in case the weather is not in our favour.
I saw the beach at Bury Lane garden centre that could be an option, and I know there is sometimes a funfair in central Cambridge. I am also considering Grafton Water. Thanks for your help!
