@Hannah oh no I hadn’t heard of that, sounds great thank you! I thought about colliers farm but not sure what that’s like for non walkers or in the rain, have you been?x
I have been but my husband wasn't keen and felt like there wasn't a great deal to do. I know others who love it there. Not sure about non walkers though as the play area may be for kids who are able to walk and play in there. There is a play area and small barn area inside though. But you will have to check to see if there's availability as it does book up fast especially on special occasions. I'm really hoping the weather is nice on Friday or at least dry. There's an event in Caerphilly Castle court area where they have animals on display there. We plan on taking our daughter to see them.
Have you been to plantasia tropical zoo in Swansea? It's all indoors and pram friendly too. It does have slopes to go up and down but only small ones and when I went last month I managed with my daughters pram and it's a large and heavy one too.
