Shipwreck Point is home to some of the healthiest reefs on Curaçao. You find elkhorn coral all over the place. Plus, the fish life is incredible. It’s as if all the fish left home and moved to Shipwreck Point. We see thick schools of yellowtail snapper, jack and chromis. —Jeremiah Peek, General Manager Of Ocean Encounters, Curacao

Signature Site

Touch of Gray is a deeper dive at 80 feet. It can have some current, best for more experienced divers. The site has an underwater canyon that leads to a big arch where you often find baby gray reef sharks. You’ll also see large schools of snapper and whitetip reef sharks that aggregate there because of the current. —Byron Kay, Owner And Operator of Kona Honu Divers, Hawaii
