Yes, Lac de Sauvebelin is another great place for the kids. I love the hairy pigs there.
Yes Jo i have been to zoo de Servion 3 times recently. It is a fantastic zoo. Not too big but just the right blend of animals. I was suprised to find bears, lions and tigers there as well as kangaroos with babies in there pouches.

Really interesting animals. Very clean, FAB play area for kids and a great huge restaurant. Highly recommend.
