11 nights
Oct, Nov, Dec

Journey with us onboard the beautiful Mermaid II Liveaboard to the reefs of Raja Ampat, Halmahera, and the critter capital of the world-Lembeh Strait in North Sulawesi. This 11-night snorkeling safari is a one-way route from Raja Ampat in the east to Lembeh Strait to the west.

The focus of this unique trip will be Halmahera, but because the most convenient starting point for this itinerary is in Sorong-the port to Raja Ampat, we will be spending about 3 days snorkeling some incredible reefs around Misool before we move west towards Halmahera. In Raja Ampat we’ll spend time among the amazing soft coral reefs that surround Misool island, we’ll explore manta aggregation areas, some of the world’s most pristine reefs which are full of fish, and with a bit of luck we’ll be able to get in the water with a whale shark or two.

Halmahera is one of the final frontiers for snorkeling in Indonesia, a string of islands located between North Sulawesi and Raja Ampat. Mermaid Liveaboards have been pioneering safaris into Halmahera for the last few years, there are only a few operators that have experience in this remote archipelago and many of the snorkeling sites we visit are yet to be formally named. We’ll spend about 6 days snorkeling over the beautiful shallow coral reefs in complete seclusion – the chance of meeting divers or other snorkelers is extremely unlikely.

While in the area, we’ll encounter a diverse range of fish and corals. Cruising blacktip reef sharks are regularly seen and large rays often pass by, as do Napolean wrasse, bumphead parrotfish, tuna, and giant trevally. The reefs are mostly gently sloping from the small islands in the area and have a wide variety of coral species including beautiful fans, huge barrel corals, fields of staghorn coral, and lots of colorful soft corals swaying in the shallows.

Some snorkels will also be over more sandy patches littered with broken-up and dead coral pieces. Here we can hope to find lots of parrotfish and triggerfish building nests, scorpionfish hiding, and some weird and wonderful critters like sea moths, garden eels, frogfish, and more. We can expect to see large schools of mackerel, batfish, and unicornfish on most of our snorkels. Schools of trevally are also common sights, as well as turtles, sea snakes, eels, various crabs, shrimps, pipefish, and of course, nudibranchs. Walls of pink and purple basslets cloud the reef along with schooling yellow snapper and fusiliers. It is not uncommon to see 5 or more species of each- butterflyfish, parrotfish, triggerfish, anemone fish, angelfish on each snorkel site!

Night snorkels are great in this area with lots of cuttlefish, various octopus species and squid out hunting, small rays and crocodile flatheads out and about, as well as the Halmahera Epaulette Shark (a type of bamboo “walking” shark) which can be seen scurrying along the shallows after dark.

Not to mention the incredible topside scenery where volcanoes and tiny islands jut up from the turquoise waters. From Halmahera, we’ll track west towards North Sulawesi.

Our final day of the tour will take place in Lembeh Strait where the type of snorkeling will shift slightly as we scour the shallow reefs and black sand slopes for some of the most unique marine critters in the world. Here we’ll be focusing on finding things like multiple species of frogfish, leaf scorpionfish, nudibranchs, and with a bit of luck some seahorses.

Day 1 - Arrive in Jakarta

Arrive into Jakarta International Airport (CGK) and check into the Jakarta Terminal Hotel and relax until the group meets for a late-night check-in for the flight to Sorong.

Day 2 - Jakarta to Sorong, Board the Mermadi II

Fly from Jakarta to Sorong. The Mermaid II crew will be there to greet us and take us by car to the harbor for boarding. After our welcome orientation and safety briefings, we will be shown to our cabins so that we can settle in.

Day 2 - 10 - Onboard The Mermad II

Each day begins with a “light” breakfast before starting a site briefing for our first snorkel session of the day. Each snorkel session will run for 60 – 90 minutes. Mermaid II will take us as close to the sites as possible, sometimes we will board the smaller zodiac boats and get dropped in the shallows. All the snorkel sessions have surface support, and you can jump on a tender and return to the main vessel if you prefer a shorter snorkel session.
After our snorkel we will return to our boat and dry off. There will be dry towels waiting on the dive deck for us. A full hot breakfast will then be served. After breakfast we hit the water again for another snorkel session on a nearby site. We return to the main boat for a delicious lunch (either served buffet style or plated, usually 2 – 3 courses). After a little break to allow our food to digest, we prepare for the third snorkel session of the day. Afterwards, there is usually a snack and hot beverage served (you will not go hungry on this cruise!), before we enter the water for a later afternoon or sunset snorkel, depending on the conditions and sites in the vicinity. Dinner is a 3 – 4 course meal.

Evenings are spent looking through fish ID books, chatting in the spacious lounge or enjoying the night sky from the deck.
We will offer 3 – 4 snorkel sessions a day. You are not obliged to participate in them all. Mermaid II is staffed with an excellent masseuse as well as kayaks.

Day 11 - Final day of snorkeling

The final day of snorkeling has 3 scheduled snorkel excursions to give everyone enough time to dry and pack all their gear away. We spend the night onboard in Lembeh Strait.

Please speak to a member of our team before booking any international flights. We are also available to help should you like assistance with booking these flights.
