The New Moon Spawning, 10 nights liveaboard itinerary on Palau Siren offers something few divers ever get to see. Guests joining one of these special itineraries have the privileged opportunity to witness one of the most dramatic and biologically important marine events in Micronesia; large-scale aggregations of spawning bumphead parrotfish (bolbomeotpon muricatum) that predictably linked to new moon lunar cycles.

Maps & Itinerary

Palau Siren’s New Moon Spawning liveaboard itineraries are scheduled to coincide with the period when thousands of bumphead parrotfish gather in one area of Palau each month to procreate. Around the time when this event is expected to occur, your Cruise Director will give a number of informative presentations about the unique spawning dives which make this liveaboard diving adventure truly special.

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

Diving on these itineraries is mostly within the Rock Islands Southern Lagoon, a UNESCO World Heritage Site, with a day at Peleliu. The islands have narrow channels and current flows that change with the tides making navigation around some parts of the lagoon more ideally suited to the skiff tenders. Additionally, Palau Siren and all other liveaboards in Palau are mandated to use specific mooring areas and anchorage points scattered around the Rock Islands, meaning that cruising within the lagoon and around the islands is minimal. Dive groups are dropped off and picked up at the dives sites by the skiffs with transfer between the main vessel and most dive locations usually taking 5-15 minutes depending on where Palau Siren is anchored.

In addition to the spawning dives, on some itineraries we offer 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 all manner of weird and wonderful creatures from the depths head closer to the surface to feed.

The crew was wonderful, the boat was clean and well-maintained, and the diving was absolutely breathtaking. ​The dive guides were excellent and prioritized safety while ensuring every guest had a great experience.

Pedro and his team were simply amazing - tending to every need our request without hesitation. Their hospitality cannot be overstated and their desire to see each guest taken care of matches their generous attitudes. The food was incredible and quite plentiful. The schedule was appropriately busy with time in between to recharge and no opportunities to dive were lost. I cannot give a higher rating and look forward to another trip! Thank you Palau Siren!

Palau Siren, April 2025 - New Moon Spawning
This was our 2nd Master Liveaboard trip, so expectations were high! Crew: The crew and dive staff were top notch - they do everything to help you, feel at home. Food: Delicious! Loved it. Diving: Really enjoyed every dive, the variety, the dive sites. Everything was so good. Our highlights were: the bumphead parrot spawning dives, the hook dives with loads of jacks & sharks & beautiful coral reef dives (german channel) with loads of groupers and last but least loads of turtles. Rooms: Very spacious and top notch. Safety: One of the best safety protocols I've seen on many live-aboards. In short - can only recommend to dive with this company !

Palau Siren, January 2025
Excellent trip with one of the nicest crew I have sailed and dived with. Safety consciousness as well as hospitality was top notch. Kudos to the incredible dive team. Thorough briefings and unrushed dives. Especial shout out to Ann and Evo who are super sweet, they remember every guests name and welcome everyone back after each dive Ann is an amazing massage therapist to boot. The best hostess I have seen on any liveaboard.
Great time on Palau Siren

Palau Siren, December 2024
The cabins were some of the largest I've seen on a liveaboard, and the beds were very comfortable. The food was excellent and featured a large variety. In particular, hosts Evo and Ann went above and beyond to make the guests feel at home. The diving was great, and there was a nice variety between hook-in dives, reefs, a wreck, and the caves. The skiff that took us to the dive sites was comfortable and spacious (an actual boat rather than an inflatable.) Overall, I would recommend this trip!
