For several years when our children were younger we used to drive past and wonder what went on in this attractive park that happened (at the time) to have a life size model of a polar bear prominent by the roadside!
A few years ago we actually went in and enjoyed the adventure trail round the lovely parkland looking for answers to 20 explorer related questions. The trail changes every few years and for the past couple of years has been Pirate themed. In addition this year has also seen the profile raised for the existing "Menhir" trail that takes in several standing stones on the site and now has a separate set of Prehistoric questions (and some smaller than life dinosaur models).
A well cared for attraction, the house is also worth a visit (no extra cost) as well if you enjoy such things and guided tours are available (free) in a variety of languages. Modest prizes are earned for the successful completion of the trails and the friendly staff have embraced the "yo ho ho" element of the pirate theme! There is a cafe bar, souvenir shop and a small children's play area as well.
If you are in this part of the Vendee and it is a little too cool for the beach, or you would like a change from sitting in the sun, you and your children (5 - 11 ish) will enjoy it here. Like many other attractions in the area it stays open for a little longer than one is accustomed to, not closing until 2100 at the height of the season.
And the polar bear - he is still there but moved away from the road!
