Our Special Full Moon Spawning itinerary on SY Palau Siren offers guests something truly extraordinary. Guests joining these cruises will have a chance to witness one of the most spectacular natural events on earth; the spawning aggregations of the red snapper (lutjanus bohar) at full moon lunar cycles.
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.
On a typical day we offer up to 4 day dives; 3 day dives and a fourth sunset or night dive. The diving day is scheduled as follows:
- Light Breakfast followed by a briefing and Dive 1
- Full Breakfast, relaxation period, briefing and Dive 2
- Lunch, relaxation period, briefing and Dive 3
- Snack relaxation period, briefing and Dive 4, where possible

Launched in April 2011, the 40m S/Y Palau Siren was built on the Indonesian island of Sulawesi and is handcrafted from ironwood and teak (traditional to the area). You will find no other diving liveaboard as beautiful in Palau waters, and being built by divers for divers you can be rest assured that every need has been thought of and addressed.
Welcoming a maximum of 16 guests per week ensures that there is ample space to relax. The 8 cabins are doubles or twins and 2 cabins are flexible double/twin and offer individually controlled air conditioning and ensuite bathrooms with hot water.
