Maps & Itinerary

During full moon spawning, red snappers aggregate to show their own similar spawning spectacle full of energy and excitement. Not surprisingly, these events also attract the biggest predators in Palau such as oceanic blacktip sharks, grey reef sharks and very occasionally even a hammerhead. Watch how they hunt actively within the large school of spawning fish. It is something only a select few people ever get to witness and you can now be one of them.

In addition to these special spawning dives, you will have the opportunity to experience ‘Blackwater’ diving in Palau. Imagine rolling off the boat in the pitch black of night, sometimes many miles away from the shallow water of the reefs, to watch one of the largest migrations on earth as all manner of weird and wonderful creatures from the depths head closer to the surface to feed.

From post larval fish to Cephalopods, many smaller than your finger nail, these amazing dives present some of weirdest creatures you are ever likely to see without a submarine.

During the period of the cruise when the spawning occurs, your Cruise Director will give a number of presentations about these unique dives. These informative talks will cover everything from the ecology of these events to the best way to photograph them. For the diving, the group will be split into two teams of eight divers to witness these spectacular events, thereby maximising the experience and ensuring that we only observe, not interfere with, this spectacular behaviour.

Please note that these dives are only for the experienced diver as there can often be very strong currents at the sites where the action is happening.

Perfect diving within Palau. Unfortunately only less diving in the Peleliu area. would be nice if diving would have been extended there. Also it would be good to make a standard of minimum 100 dives experience prior to the trip.

Blown away by our experience on this liveaboard. The diving has been incredible but the way the Palau Siren is run and the staff on board has taken out trip to another level. If you want a trip in the hands of a professionally run liveaboard with first class customer service and incredible food this is the one. Thank you
