Souillac is a small town on the south coast, one of the rougher and more dramatic parts of the island. The sea here is exposed and often stormy — not ideal for swimming but striking to look at. Gris-Gris beach nearby has towering black basalt cliffs that get battered by waves; it's one of the most atmospheric spots on the island.
Rochester Falls, a few kilometres inland, is a flat-topped waterfall where the river cascades over distinctive hexagonal basalt columns — unusual-looking and accessible by a short walk through sugar cane fields. The nearby Telfair Gardens are peaceful and free.
