Wells House is just outside Gorey so as a Dubliner it only takes an hour to get too and is a definately must for family day. A fantastic place for young kids.
The animal sanctuary is a "must visit". Kids can feed bottle feed the goats...go for a horse ride and feed the pigs and other animals. It's all supporting rescued animals so it's all in a good cause.
There is a large playground and archery centre and not to mention the huge forest with the fairy tree and the statue of the Gruffalo. Entrance fee is €8 per car no matter how many people you have in it. We never did the tour of the house as we have younger kids but there was a good amount of people doing it so it must have been good!!
We never ate in the coffee shop either as we brought our picnic but everything seemed very easily priced...
