Green Bay is a dive site with a series of small caves, swim throughs, drop-offs and statues. The site has a particularly high biodiversity. The caves are home to moray eels, octopus, groupers, cardinal fish and more. The fish are often fed and are used to divers. At a depth of 8 meters lies the Fish-Finding-Rock. If you hit this rock with a stone, thousands of fish rush toward you. Green Bay is widely used as an exercise site and is also suitable for snorkeling and free-diving.
