Wear bright colors to attract the butterflies fluttering around giant plants and a forested canopy at this mesh-encased farm. As practical as it is magical, here you can learn about chrysalis stages and how cocoons form; tickets include a 20-minute guided tour in French. Come early to see the butterflies at their most active. Admission is valid for the duration of your stay on the island. It's signposted 1.5km south of Orient Beach.
Look out for monarchs, Caribbean longwings, blue morphos and hundreds of other species from Asia, South America, Africa and Australia, as well as colorful caterpillars.
