Skip the swimming here; the currents are lethal. This spot is all about the raw power of the Indian Ocean smashing into basalt cliffs. Spend 30 minutes watching the waves at La Roche qui Pleure, a rock formation that literally mimics crying when water hits it. Bring a windbreaker because the breeze is relentless. Grab a local snack from the stalls near the parking lot and move on. It is loud, dramatic, and totally worth the detour.
