12 nights

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 Lembeh Strait in the west through Halmahera and finishing in Raja Ampat.

The focus of this unique trip will be Halmahera, but because the most convenient starting point for this itinerary is in Lembeh, we will of course spend a full day snorkeling the unique reefs in the area looking for those unusual critters before moving on to Halmaherea and then later Raja Ampat, where we will spend the last few days of the trip.

Colorful reef fish and reef with snorkeler in Halmahera Indonesia

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 around five to six days snorkeling over the beautiful shallow coral reefs in complete seclusion – the chance of meeting divers or other snorkelers is extremely unlikely.

Our first snorkeling 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.

As we enter Halmahera, we’ll encounter a diverse range of fish and corals. Cruising blacktip reef sharks are regularly seen, as are Napolean wrasse, bumphead parrotfish, tuna, and bluefin trevally. The reefs tend to offer a large shallow plateau which will usually slope away from the islands. Halmahera is famous for its wide variety of coral species which includes beautiful fans, huge barrel sponges, fields of hard corals, and on certain sites colonies of colorful soft corals. With regards to marine life, one of the things most iconic to Halmahera is the constant explosion of masses of colorful reef fish, like chromis and anthias, from the reefs. Other creatures you might come across are sea turtles, sea snakes, eels, various crabs, shrimps, pipefish, heaps of anemone fish, and nudibranchs.

Night snorkels are great in this area with opportunities for 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 epaulet “walking” shark) which can be seen plodding along the shallows after dark.

From Halmahera, we’ll track east towards Raja Ampat where the underwater beauty and bounty will continue, only now we have the opportunity for mantas and wobbegongs!

This snorkeling safari is escorted by a Snorkel Venture team member.

*Please note that this particular itinerary covers a lot of territories and therefore involves several overnight crossings between regions where we will be in the open sea and more exposed to the elements, particularly swell.  If you have any reservations or hesitations about what it’s like onboard a liveaboard, please get in touch with us and or read this blog about what you can expect for a liveaboard itinerary such as this.

Day 1 - Meet the group in Jakarta

On arrival in Jakarta (CGK) you will check into the hotel and relax before a group dinner where you can meet your fellow tour participents, and the Snorkel Venture group leader. Over night in Jakarta.

Day 2 - Arrive in Manado

On arrival in Manado we’ll be met by a member of the Mermaid team who will drive us to the port-about one hour-where the Mermaid II boat is waiting. We will check in, unpack and relax before be a full boat briefing as well as a brief overview of the following day’s itinerary. This will be a non-snorkeling day.

Day 3 - Snorkeling in Lembeh

Our first day of snorkeling will include three snorkleing sessions at different sites around the Lembeh Strait. Here, we will explore the shallow reefs for the unique critters that dwell there.
Each day begins with a “light” breakfast before starting a site briefing for our first snorkel session. Each snorkel session will run for 60 – 90 minutes. From Mermaid II, will board the smaller zodiac boats so we can safely be dropped in the shallow. 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 morning 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 buffet lunch, usually 2 – 3 courses. After a little break to allow our food to digest, we prepare for the third snorkel session of the day. Afterward, there is 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.

We will offer 3 – 4 snorkel sessions a day. There may be a day or two when we have to make a longer crossing where we will do two longer morning snorkels. You are not obliged to participate in them all. Mermaid II is staffed with an excellent masseuse as well as kayaks.

Day 4 - 11 - Halmahere and Raja Ampat from Mermaid II

From Lembeh, we will sail overnight to a small island between Lembeh and mainland Halmahera called Tifore. Tifore is a part of the Halmahera region and has some great reefs to explore in clear blue water. From Tifore we will then cruise again overnight to the Patinti Strait where we will remain for the next three to four days.
The Patinti Strait is the narrowest point between Halmahera and the smaller island of Bacan where all the area’s best snorkeling is located. The numerous small islands and extensive coastline of both Halmahera and Bacan provide us with tons of exceptional shallow reefs where anthias and chromis explode from the reef like multi-colored confetti!
After our time in the Patinti Strait will make an all-night crossing to either Pulau Pisang-a small island volcano between mainland Halmahera and Raja Ampat that is a part of the Halmahera territory, or Kofiao-a set of islands that are on the very west or Raja Ampat. The decision as to which area we will stop at for a day of snorkeling will be based on the weather at the time of the crossing. We will spend the day snorkeling the reefs in either of these islands before making another all-night crossing into Raja Ampat.
Depending on sea and weather conditions, we will either start our time in Raja Ampat in the very south-Misool, or in the Fam Islands. The decision as to where we will start our Raja Ampat snorkeling will be made a few days before the crossing when we have a better idea of what sea conditions are like. If we start in Misool, we will spend at least a full day there exploring the beautiful reefs before cruising overnight to sites in the north for some more epic snorkeling where we hope to have encounters with things like mantas, wobbegongs, blue water mangroves, jetties, and the opportunity to stretch the legs with a nice viewpoint tour.
If we cross from Pulau Pisang or Kofiao into the Fam Islands, we’ll have lots of time to explore and indulge in all the iconic snorkleing sites and marine life that make Raja Ampat famous. The areas around the Dampier Strait are where you can find shallow cleaning stations for mantas, wobbegongs become a lot more prevalent, walking sharks can be found on night snorkels, village jetties are a safe haven for large schools of fish, while the reefs around the mangroves offer us one of the most beautiful and unique snorkeling environments.
The final day of snorkeling will either offer two scheduled snorkel excursions to give everyone enough time to dry and pack all their gear away. We spend the night onboard Mermaid II in Sorong Harbor.

Day 12 - Disembark and return to Jakarta

After breakfast and check out and say goodbye to our hosts- the amazing crew of the Mermaid II. We will then all transfer to the Sorong airport together and check in for our onward flight to Jakarta. The tour ends upon arrival in Jakarta where we bid farewell to our new friends.
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.
