At low tide the rocky shelf between the medina's sea wall and the open beach exposes an extensive system of pools, channels, and wave-cut platforms that stretch for several hundred metres. The pools hold starfish, urchins, small crabs, anemones, and the occasional octopus. Children love them; the scale is surprisingly large for a Mediterranean or Atlantic coastal city.
The best access is from the steps below the Skala de la Ville, heading south toward the beach. Low tide times are posted at the fish market. The light in the late afternoon on a clear day is excellent for photography — the wet rock reflects the sky and the waves break white beyond. Wear shoes with grip; the rock is slippery with algae.
