Explore Spectacular Coral Reefs from a Liveaboard Boat in West Papua
Snorkeling with Whale Sharks in Cenderawasih Bay
Overview
With pristine reefs, white-sand beaches, and dramatic karst cliffs, Cenderawasih Bay in West Papua is stunning. Set in the heart of the Coral Triangle, Cenderawasih is also a biodiversity hotspot renowned for its endemic reef fish and corals. Aboard our 100-foot liveaboard schooner, we’ll explore its hidden gems—with a bonus of two days of snorkeling and swimming with whale sharks at a special location that puts us in close proximity with these majestic creatures. It’s one of the most thrilling wildlife encounters on the planet! We’ll also visit villages and take island walks to look for extraordinary birdlife, including the bird of paradise (“cenderawasih” in Indonesian), for whom this bay is named. This is a phenomenal natural history adventure!

Itinerary
Please be aware that this itinerary is designed to be flexible. Although we will visit all the places listed on the itinerary, we rarely follow the schedule as described exactly due to weather, tides, preferences of trip members, and other factors. Come prepared to be flexible!
We embark on a traditional Indonesian schooner that will take us to some of the best snorkelling spots in the Coral Triangle. This afternoon on Kalilemon Reef be sure to watch for the recently discovered Cenderawasih longnose butterfly fish, with its bright yellow body and featherlike dorsal fins. Dinner this evening is followed by a presentation about whale sharks—the fascinating creatures we hope to see tomorrow.
Whale sharks are the largest fish in the ocean—some are the size of a school bus! Swimming with them is an unforgettable experience, and we've found a location where we should be able to snorkel for several days in close proximity with the gentle giants. We also visit a village, meet residents, and discover the local culture.
Take a short hike through mangroves in search of the exquisite lesser bird of paradise in its flamboyant mating plumage. Then set sail for the crystalline waters of Bird's Head Seascape, an epicentre of marine biodiversity where we'll look for divaricate soft coral, feather stars, manta rays, hawksbill turtles, and leatherback turtles. Interesting geology topside and incredible topography beneath the surface make for fascinating snorkelling.
Today we snorkel with 100-year-old giant clams, which can reach four feet in length and weigh over 500 pounds. They're sometimes referred to as “man-eating” clams, but don't worry—their main foods are algae and plankton. We'll set off on a birding walk in search of hornbills, kingfishers, parrots, and eagles, all common here. Later, villagers welcome us to their homes; the local children are eager to interact and practice their English.
A morning sail takes us to brilliantly colored hard corals in the shallow Numamuran Strait, where the jungle descends right into the reefs and the snorkelling is stunning—look for Acropora branching corals, large boulder coral colonies, and cushion stars. We paddleboard around the picturesque anchorage, keeping our eyes peeled for dugongs—relatives of manatees that graze on underwater grasses.
We begin the day snorkelling above a Japanese Zero fighter plane resting in just 30 feet of water—a WWII relic that's now home to colorful fish. Hawksbill and green turtles, barracuda, and surgeonfish (think of Dory, from Finding Nemo) all live in the area. In the afternoon we snorkel in a new spot, with sea fans, blue sea stars, huge barrel sponges, an amazing array of hard and soft corals, and bright sea whips on reef “islands” above a white sand bottom.
We anchor near Yop Island and travel by dinghy into Korio Bay, where the bird and plant life are spectacular. Be sure to have your binoculars with you as we search for the dramatic Blyth's hornbill and eclectus parrots, which are easy to spot because of their bright red and green plumage. On our afternoon snorkel, watch for the colorful Nursalim flasher wrasse and the brilliant blue Giti's demoiselle.
Auri's spectacular karst islands rise above the water's surface like the backs of gigantic green sea monsters. Underwater, the scenery is just as incredible, with pristine coral reefs, colorful fish, and a trio of American WWII fighter jets sunk in the shallows. Our days are filled with jaw-dropping beauty as we explore crystal-clear waters and enjoy lunchtime beach barbecues along white sandy shores beneath palm trees. We'll be snorkelling and paddleboarding in paradise!
We sail overnight from Auri on Day 10 and disembark in Nabire this morning. The crew will take your checked luggage to the airport. After breakfast, transfer to the airport for departure.

Cenderawasih Bay is very close to the equator and has a warm, tropical climate with year-round temperatures in the high 80sºF and occasional rain showers.
The cook on board prepares simple and tasty meals, a mix of Asian and Western styles with seafood and plenty of fruit and vegetables. There is bread and fruit available for breakfast, as well as eggs upon request. Lunch and dinner are served as a group, and snacks are available as well. There are plenty of vegetarian options.
During the snorkels and land excursions, we will take a small dinghy to each site. The dinghy will always stay with the group so that you can return to the boat at any time.
Cenderawasih Bay is largely protected from the southeast winds that prevail during the summer months, so the majority of our trip takes place in calm waters. There is a higher chance of rough seas when we are in the northern, more exposed areas of the bay. We will always monitor the weather conditions and make changes to our route if necessary.
The Cenderawasih journey takes place in an extremely remote and uninhabited bay in the Pacific. In the case of serious illness or injury, medical attention and swift evacuation are not available. Once we sail from Nabire, we are far away from towns and medical facilities. In the case of serious illness or injury, we will make every effort to reach medical facilities as soon as possible, but be aware that it may take the boat days to return to the port of Nabire. If you have health or medical issues of concern, please discuss them with your physician before considering this trip.
Client Testimonials
"This trip met all of our expectations! For anyone wanting to be able to see and snorkel with whale sharks, this is the trip to take. The other snorkeling sites were also exceptional, and the hike through the jungle to see the Lesser Bird of Paradise was fantastic! Our visit to a small, remote village to meet and interact with the local people was also very special and heart-warming."

"This trip is a secret gem in the WT catalog. Not only do you get the whale sharks, but you also get the coral and pretty fish that the area is known for. You also get some Birds of Paradise and time with the locals. What's not to love?! "

"What an expedition! Snorkeling was the focus and it was most excellent—everything from gorgeous coral, bat caves, myriad fish and other sea life, giant clams, WW II plane wrecks (we even found a fourth wreck), and even whale sharks! There were five our first time in the water with them. What a thrill to be so close to these enormous fish! And in an uncrowded environment."
