A Caribbean experience rich in pristine landscapes awaits you on this beautiful Antilles island. With its volcanic spires that are both emblematic and idyllic, the peaks of Saint Lucia unravel their magic on land just as they do under water. On the surface, there is more than a hundred varieties of plants as well as thirty species of bird having been identified within the tropical rainforest. Coral reefs, multicoloured fish, sea turtles or even whale sharks can also be observed from within the submerged section of the peaks.
