A word from Dom :  “The Indo Siren is a crowd-pleaser. She’s comfortable & well-appointed with a touch of luxury, catering especially to underwater photographers. She’s a terrific option to consider but be aware … she’s often fully booked.”…. Dominick Macan

Indo Siren concentrates her time on the most popular regions of Indonesia – Komodo & Raja Ampat.  However, from time to time, you’ll find trips nestled into the schedule which will whisk you off to lesser-visited regions:  Banda Sea, Alor,  Ambon, Triton Bay. Halmahera, North Maluccas, Forgotten Islands, Spice Islands …. and various combinations of those site.  Trips to specific regions are, of course, based on the best time of year to experience the region’s finest diving.

{slider See the itineraries & map for Indo Siren ….. open |dest|closed} OPULENT DIVING:  There aren’t enough adjectives in the world to describe this massive, complex and fabulous island nation.  Exhilarating wall dives, throbbing schools of fish, captivating colors, healthy coral & sponge gardens, the world’s best “muck” diving, the tiniest, most extravagant of Earth’s creatures …. plus a mix of large predators – mantas, sharks, dolphins & whales. The Indo Siren will take you there …..  So, here we go in alphabetical order:

Ambon – If you love crazy critters, Ambon is hard to beat. Get your lens ready for rhinopias, pegasus sea moths, countless varieties of frog fish, seahorse, flamboyant cuttlefish, ghost pipe fish and star gazers. Lesser known is the south side of Ambon, which features great colorful walls, caves, swim throughs and healthy reef life with large fish … and more critters.

Banda Sea, Alor – In Alor & the Banda Sea, you’ll find clear waters full of masses of fish & loads of invertebrates … plus alluring critters. As to topography, you’ll find shear drops, huge pinnacles, great walls … all covered with rich & thriving corals which attract diverse fish life. Add to that, visiting pelagics and you have a magical mix.

Halmahera & Maluccas (including Misool & Lembeh) – Halmahera is the largest island in the Maluku chain, features sparkling clear water, loads of fish, some super drift dives, healthy, thriving coral reefs, some fascinating mangroves with intriguing critters … and fabulous volcanic landscapes. Some of the sites border on the deep blue and put you up close to grey reef sharks, eagle rays and immense schools of blue fin trevally.  Lembeh Strait is the undisputed critter capital of the world and it will WOW you with its weird & wonderful species.  In Misool, you’ll dive amongst splendid corals, experience drift dives & swim throughs, see large schools of pelagic fish and brightly colored reef fish.  It’s pure magic.

Komodo – Perhaps the most diverse of all diving in the Indonesian archipelago. There are seamounts, walls, canyons and pinnacles as well as the spectacular coral gardens. There a hot spring at an underwater volcano, great night dives on black sand slopes with creepy, crawly critters. Numerous sites tout pelagic fish, sharks & mantas but, be assured that at each dive site, you’ll experience something different.

Raja Ampat – Indonesia’s shining underwater star, Raja Ampat has something of nearly everything a diver could want. You’ll dive channels, plateaus, walls & caves … and just plain mud, for the delight of “muck” diving. You’ll swim amongst great swirls of fish and feast your eyes on sponges & corals in scintillating colors. You’ll meet up close & personal, everything from pygmy seahorses to colossal manta rays.

Triton Bay – Divers love the whale sharks who visit the fishing platforms, but the true star of this region is a profusion of speculator soft corals gardens & the schooling fish – anthias, damsel fish, fusiliers, sweetlips & snappers. With lots of nutrients in the water, photographers beware : the viz is limited at many sites. But, you’ll love the massive black coral bushes, the drift and wall dives and the opportunities for critter hunting.
