Meet at the Porte d'Enfer car park in the commune of Anse-Bertrand.
Note: The trail runs along the coast the entire way, so it's pretty hard to get lost.
(S/E) After walking along the Porte d'Enfer lagoon, you will reach the cliffs.
(1) Continue on to reach Pointe Percée, which is now broken.
(2) Continue on to reach Pointe à Desbonnes, Pointe à Tortue and finally Pointe du Souffleur. At Pointe à Tortue, admire the Trou du Souffleur, a kind of sea cave with a collapsed roof.
(3) Continue along the coast to reach Pointe du Souffleur and admire not one, but several blowholes.
(4) Return in the opposite direction to the car park where you started (S/E).
