I quite fancy getting on a train with my 6 and 2 year olds and visiting some corner of the UK for a day trip or over night stay, but I'm not sure where to go. Admittedly I'm not massively well travelled.
Does anyone have any suggestions of places I can get to that have a few nice things for small children to do and see that's easy to get around? Open to any suggestions, doesn't have to be a major city. Bonus points for places that are generally pleasant places to visit and easily accessible by train. I'm based in the North West.
