Best of Borneo & West Sulawesi, Indonesia 2025

August 29 - September 10, 2025

We will embark on an epic journey that will take us between the islands and reefs rising up from the Makassar Strait aboard the world-renowned boutique liveaboard, Arenui. Each island has its own unique character. We can see entire schools of manta rays at Sangalaki that are drawn here to feed on plankton. As well as turtles, Derawan has elusive treasures to be found; here we search for hidden critters. Maratua hosts massive marvels, such as sharks, barracudas and more mantas! At Kakaban island, plunge into the saltwater lake full with non-stinging jellyfish in the middle of the island. Dive the incredible walls encircling the island of Kakaban. In the shallow waters encircling Samama, we scan for an abundance of macro critters, hiding in plain sight. Moving on, we cross over to the Sulawesi side of the Strait. We will follow the coastline to see the many picturesque islands and bays. We can expect to dive large reefs with immense soft and hard coral coverage, incredible pelagics, including sharks on almost each dive.

Travel Insurance: 

Travel insurance is optional. However, over the years, we have seen how valuable and beneficial travel insurance can be. These policies will help cover the expenses when your trip is interrupted due to events such as weather, mechanical breakdowns, missed flights/connections, or when someone else has a dive/medical emergency that prevents you from diving.  

We want to help offset the cost of travel insurance and will sponsor 5% of the cost as store credit if you use the links from our website to purchase travel insurance from DAN. We highly recommend it!
