In 1947, a few hundred meters from the sea, around a country house whose keep is the only remnant of a 12th-century fortress, the Pellerin family laid out a 4-hectare garden. The garden has continued to evolve and now features more than 1,200 plant species, all of which are evergreens native to most of the southern hemisphere.

Who undertakes the hike with a dog: Dogs (even on a leash) are not allowed in the nature reserve. Unfortunately, this was not mentioned in our hiking guide, so we had to switch to the beach, where you are not allowed to be with the dog at certain times. So it's best not to walk here in the high season and in the middle of the day.
