I second the ice cream farm just came back from there today, there is animals and a play area and mini activities, a shop, a cafe and a indoor play area. Not forgetting the ice cream I have just had cherry crumble
Try the Ice Cream Farm in Tattenhall for small animals (free) or, if the 7 year old is adventurous, the Crocky Trail in Waverton is great. £10 per person I think but loads of slides, bridges, mud, etc...
the zoo.is a full day. Also, Cheshire Oaks shops - if you are into that kind of thing, but that is more Ellesmere Port (but only down the road) lots of stuff to do around there, Sea Life centre, cinema, eateries, bowling.
As for Chester - boat trips on the river, walks around the.city centre.
My mind has gone blank so.hopefully somebody will be along with more stuff for you to do soon.
I loved Chester as a child, there were always Roman soldiers walking around and it's got a lovely atmosphere.
Booked to go to Chester for a few days over Easter. No idea what is available - Please can someone tell me what is fun to do there or within one hours drive of there? I only know that they have a zoo. Thanks.
