A jagged, rocky outcrop is located a hundred yards from shore, dubbed "El Diente" (or "The Dragon's Tooth"), by locals. Historically a popular landmark to test one's swimming prowess by reaching, the rock is large enough for two or three adults to fit comfortably at any given time without getting in each other's space or being too near the edge. The growths of algae along the sides of the rock and the waves which wash over its lower parts at high tide, however, make footing treacherous, and the sharp stone that makes up the steeper protuberances discourages all but the most daring from climbing to the very top. El Diente is also a frequent resting place for ocean birds, and evidence of their habitation may be found in feathers, nests, and prodigious amounts of guano.
