Journey into the world’s masterpiece of reef and ritual.
Journey into the world’s masterpiece of reef and ritual.
WONDERS OF RAJA AMPAT
Raja Ampat is living proof of what the ocean can be. What draws us here is a chance to feel part of something bigger. To sail Raja Ampat and its hidden horizons is to enter into one of Earth’s great sanctuaries, and to see that wonder is everywhere around you.

October to February, for calm seas and the best conditions for snorkeling and wildlife experiences.
Slip into shallow waters where life schools in impossible numbers. Sit with island communities whose care for the ocean show a different philosophy for life. Enter the forest to see birds perform their dance of life. These are the highlights that stay with you long after the sails are furled.
Note: Wildlife is wonderfully wild. Which means encounters aren’t staged or guaranteed. Let nature’s gifts surprise you.
SeaTrek sails four different routes through Raja Ampat. Some focus only on the archipelago, while others carry you further east into Papua or west into the Spice Islands of Maluku. Each route brings its own highlights, from whale sharks in Triton Bay to the spice markets of Ternate, all routes reveal a different side of this extraordinary seascape.

(Joshua Edwards/SeaTrek Sailing Adventures)Are you curious how to tell one coral reef system from another, or eager to uncover the stories etched into these ancient seascapes?
Seek out our Rare Routes. On these expeditions, you’ll sail alongside a coral specialist, a marine biologist, a cultural expert, or a seasoned naturalist — people who’ve devoted their lives to understanding this remarkable world. They don’t just share knowledge, they open doors. It’s the closest feeling you can have to sailing with Wallace, Darwin, or Attenborough.
Every great adventure is made possible by the hands and hearts that protect these islands. From coral gardeners and master boat builders to culture keepers and conservationists, meet the local heroes and explore our photographic journals that will bring your SeaTrek voyage to life.
Guest testimonials and travel experiences on our Raja Ampat routes.
“Seatrek Sailing Adventures trip through West Papua and Raja Ampat was a brilliant blend of activities (snorkeling different reefs, twice a day) and relaxing moments aboard the gorgeous wooden pinisi boat, the Ombak Putih. The whole crew are so chilled and friendly, quietly looking after you the whole time. I couldn’t recommend them highly enough – it was my second trip with Seatrek.”
“We are just back from a SeaTrek trip in Raja Ampat, on board MS Katharina, and it has been just absolutely incredible. The scenery and snorkelling are completely out of this world, but what really made the trip were the boat and the crew.”
This is a snorkeling only trip so all of the sites were very appropriate and enjoyable for the snorkeling, be it schools of fish, beautiful corals, stingless jellyfish, whale sharks , dolphins. Every day was a new wonder. … This was a trip of a lifetime, actually we are considering doing it again so maybe can’t say its a trip of a lifetime as there may be many more
“This was our second trip with SeaTrek, this time on the Katharina sailing around West Papua and Raja Ampat as a family with our college-aged daughter. … The variety and all the different colors of the coral in Raja Ampat is hard to describe, but it was one of the most alive and vibrant coral snorkeling trips we have ever been on. The abundance of reef fish, sea turtles and occasional reef sharks added to the amazing experience on each snorkeling adventure. Of course seeing and watching three different types of birds of paradise was the icing on the cake, as was seeing the dolphins swim by the boat as well as the whale sighting.”
“What a wonderful and unique experience with memories that will last a lifetime. I had the pleasure of sailing around Raja Ampat on the Ombak Putih for a couple of weeks. Through all my years of travelling around the world, this is by far my biggest highlight. The boat, crew, accommodation and meals were all 5 star. Sea Trek you blew me away. Let my photos tell the story.”
“We journeyed on the Ombak Putih around Raja Ampat. Everything about this trip was focussed on the enjoyment of the passengers. We did some amazing snorkelling, so many and such different types of fish! We trekked and saw two separate birds of paradise. We climbed mountains, and snorkelled some more. The crew were fantastic, nothing was too much trouble. Our guides were very knowledgeable and fun to be with. We will definitely be coming again.”
Our SeaTrekker monthly magazine is your passport to unforgettable experiences.

Every guest brings back a story. Some tell of rare encounters with whale sharks, others of evenings spent singing with new friends on a white sandy beach. The Travel Log is our record, a living collection of what it means to sail with us, seen through the eyes of those who’ve come aboard.
