Inland between Le Baril and St-Philippe, don't miss the 3-hectare garden, Le Jardin des Parfums et des Épices. It contains over 1500 species in a natural setting in the Mare Longue forest, 3km west of St-Philippe. Knowledgeable and enthusiastic guides present the island's history, economy and culture through the plants; tours are in French and last 90 minutes.
There's also a shop where you can buy local spices, essential oils and jams.
