Our 7 night New Moon Spawning Specials on Palau Siren offer guests something truly extraordinary. Divers joining these liveaboard itineraries will have a chance to witness one of the most spectacular natural events on earth; the spawning aggregations of bumphead parrotfish (bolbomeotpon muricatum) that occur at new moon lunar cycles.

Maps & Itinerary
At one particular time each month, around the time of the new moon, thousands of bumphead parrotfish gather in one area of Palau for the sole purpose of procreation.
During the period of the liveaboard diving itinerary when this event occurs, your Cruise Director will give a number of presentations about these unique spawning dives. These informative talks will cover everything from the ecology of the events to the best way to observe and photograph them.
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.
In addition to witnessing these spectacular spawning aggregations, you will also have the opportunity to experience amazing ‘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 all manner of weird and wonderful creatures ascend from the depths towards the surface to feed.
On a typical day we offer a total of up to 4 dives; 3 day dives and a sunrise, sunset or night dive depending on spawning times. 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)*
*Where land tours are offered, only 3 dives will be possible
*The itinerary above and indicated dive sites are an example only and subject to change at the Captain’s discretion depending on local regulations, guests’ experience, weather conditions and logistics. Adverse weather can affect the New Moon Spawning special itinerary.
Launched in April 2011, the 40m 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 Palauan 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 on each trip ensures that there is ample space to relax before, during and after diving. The 8 stylish cabins provide a choice of double or twin bed configurations; 2 cabins are flexible twins which can be converted to doubles. All cabins offer individually controlled air- conditioning and ensuite bathrooms with hot water .

Permits and fees, equipment rental, nitrox and diving courses can be pre-booked and pre-paid at the time of booking your liveaboard diving holiday.
