Uncharted Destination

All Around Eastern Indonesia

At Uncharted Cruises, we also offer the opportunity to venture into the unexplored corners of the Indonesian archipelago, seeking out untouched and magnificent experiences not found on the well-known routes. This is a rare opportunity to become part of an exploration and expedition team in one of the remaining pockets of the world where uncharted realms remain. We offer specialized itineraries that are crafted for advanced divers with a sense of wonder, eager to uncover the underwater mysteries of these spectacular destinations.

These exploratory cruises may require more effort for both the crew and guests, and we cannot always guarantee that every dive will be a success, but they also present the chance to venture into the unknown and witness something entirely novel. As we navigate through the vast and diverse waters of Indonesia, every dive with Uncharted Cruises is a step into uncharted territory, promising a true, unparalleled diving adventure.

Uncharted Origins

Bira, South Sulawesi

The birthplace of Uncharted Cruises and our beautiful Phinisi, Thalassa. Built on the beach in Kampung Phinisi, Tanah Beru by skilled craftsmen with experience carried over generations, this is where we call home.

Should you want to visit Bira and Tanah Beru and experience the hospitability, craftsmanship and beautiful surrounding nature, inquire with us and depending on where Thalassa is and where we are. We would love to welcome you to observe in awe the beautiful and intricate skills the bugis people display. The amazing diving around Bira and the tip of Bulukumba regency in South Sulawesi are still a relatively unknown gem and a further must-do for your visit to the UNESCO recognized Phinisi capital of the world.
