Dive site Da Costa is a beautiful, quiet dive site that is perfect for beginning divers and dive training. The site is sheltered and has a slowly sloping bottom. There is also plenty to see. Between just 2 and 4 meters you sometimes encounter turtles and a little deeper there are a number of statues including a mermaid, a lion and a dwarf. On the bottom grows sea grass where squid hide and lay their eggs. Other species occasionally spotted in Da Costa are sea horses and barracudas.
