How to dive Port Douglas?
Liveaboard:
The main and best parts of the Great Barrier Reef are located quite far away from the mainland. If you want to dive on the magnificent Osprey Reef you need to take a liveaboard. The best spot is called North Horn, and is famous for its resident population of Sharks.
The dive operators often feature shark feeding and you can have the chance to spot Whitetip Reef Sharks, Silvertip Sharks or the rare Tiger Shark! Many Packages are available from the low budget liveaboard to very luxurious vessels.
Most of the liveaboard trips start from Cairns but several dive operators start from Port Douglas.
Port Douglas Dive centers:
Port Douglas is closer to the Ribbon Reef than Cairns, and you can reach the best spots within 1 or 2 hours on fast boats. The most famous dive site of the area is called Cod Hole where you can observe friendly giant Potato Groupers up close. It is an excellent place for underwater photography.
