A dive experience like no other!! During the New Moon you will witness hundreds of bumphead parrotfish gathering to start their noisy mating dance. With loud bangs, the males bump their heads together like buffaloes to establish superiority over females with colour changes taking place as the fish prepare to spawn – it is no surprise they have oversized foreheads! Rising from the deep sandy bottom to the surface like a fireworks display, the fish release their gametes into the water column over and over again; a truly unique spectacle! And you'll be a spectator in all of it!

Launched in 2012, the 40m Palau Siren liveaboard 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 cruise ensures that there is ample space to relax. The 8 comfortable, double occupancy cabins offer a choice of double or twin beds; 2 cabins are flexible double/twin. All cabins have individually controlled air conditioning and ensuite bathrooms with hot water. Palau Siren also benefits from 2 shaded, high-bottom, fibreglass skiffs, nitrox compressor, equipment rental, kayaks, laundry and massage services.

I hardly know where to start! I travelled to Thailand (Phuket) for a 12 day adventure with Girls that Scuba in April 2025 and it was, without a doubt, the best dive trip I've taken since I started diving regularly in 2023. The dive sites were beautiful...so vibrant! The Phinisi live aboard was incredible. Every member of the crew from the captain to the chef made me feel welcome and safe. The food was INCREDIBLE. The dive guides were experts on the sites we saw and they were very attentive to us on board and below the surface. We were greeted after every dive with a refreshing drink and a smile. The cabins were spotless with comfy beds and a bathroom (so nice!). I can go on and on about my experience on board The Phinisi but there's more! After several days at sea we settled into our resort in Phuket for a week of land excursions and shopping. GTS does a great job balancing diving and land excursions. The hosts are friendly and knowledgeable - no task masters! Again, the food was incredible and there was plenty of it! At the end of the trip I had 17 news friends and didn't hesitate to put down a deposit for a trip to the Maldives in August 2026. I whole heartedly recommend traveling with GTS. I'm a lifer.

There were so many amazing aspects of the Thailand GTS trip. From start to finish, everything was seamlessly organized. The diving was as beautiful and awe-inspiring as expected. The boat crew was professional, knowledgeable, and incredibly friendly. I was impressed by how quickly they assisted with every aspect of diving and life aboard the boat. Weeks later, I’m still missing the fresh smoothies and bottomless cookie jars waiting for us after each dive! The “Thailand Above” portion was equally impressive, with a full yet not overwhelming schedule. Each day’s adventure was thoughtfully planned and offered a great variety, allowing us to experience so much of Phuket. Our local guide was with us each day on land and was absolutely wonderful. I really appreciated how they tailored our itinerary to the group’s interests and were always happy to make a Thai tea or shopping detour. And finally, we were so lucky to have not one, but two incredible GTS guides. Amy and Charlotte went above and beyond from the very beginning. They were quick to answer every question leading up to the trip and, once in Thailand, they were joyful, present, and personable. I’m genuinely looking forward to staying in touch with them—and with all the amazing women on our trip.

An absolutely amazing experience in Socorro Islands with one of the BEST diving, the best group of girls, crew and staff, and delicious food throughout our journey. The long boat ride was totally worth it and I enjoyed every moment of it! Highly recommend to anyone looking for an adventure of a lifetime :D

Amazing trip - very well organised, great group of women and excellent diving. Charlotte was fantastic as our group leader! This was my third GTS trip and I already want to book on another soon.

This was a wonderful adventure. All the ladies were responsible divers and I enjoyed the trip. Nautilus/Dive Ninjas/ Sea Creatures took good care of us. One area of improvement is that it was advertised we could add on a dive beforehand but when we got to Sea Creatures the day before to check in they said they did not have enough people to do the dive. Other insignificant thing was that there seemed to be some communication issues between Girls that Scuba and Nautilus as when we got onboard they had a wrong list of roommates. This was easy to fix but made it look like there was a lapse in communication. Charlotte took good care of us and handled the issue of a diver with DCS so well. It was interesting to see how professional everyone was at Nautilus with a sick diver on board. Her symptoms were taken seriously and she was quickly provided care and evacuated to safety. All the dive masters seemed safe and led incredible dives. I will definitely dive with Girls that Scuba and Nautilus again in the future. Thank you for all the amazing memories.
