The Medes were a pirate base and later a quarry before protection began in 1983. The reserve is the most studied piece of Mediterranean seabed in Spain, and the recovery of its grouper population is the case study everyone else quotes. Anchorage: Anchor off L'Estartit; anchoring inside the reserve is prohibited and moorings are assigned. Hazards: Heavy boat traffic in season and strict no-take rules; the tunnels are overhead environments. Más
