This new trail on the Montagne des Français has something for everyone: the 6km (three hours) route is definitely for the fit, climbing the mountain and negotiating a tunnel, but there's a gentle 1km route for those less energetic. You can see lemurs, chameleons, snakes, tortoises and lots of birds, including the drongo. Baobabs stud the mountain and all around are magnificent sea views. Note that it's fady (taboo) to answer the call of nature here.
