Expedition overview
An expedition to the edge of the Coral Triangle — where blue whales surface and pristine reefs begin.
Timor-Leste is one of the last true marine frontiers in Southeast Asia. Its coastline sits beside extremely deep water, creating a powerful migration corridor for large marine life.
During October, the waters between Dili and Atauro can become a passage for blue whales, sperm whales, dolphins and other cetaceans. This expedition is timed to place the group in the right region during the most exciting part of the season.
This is not a standard dive holiday. The journey is built around open-ocean whale and dolphin safaris, reef diving around Atauro, relaxed island time and a final cultural day in Dili.
Diving plan
Two dedicated whale safari days combined with Atauro Island reef diving.
The expedition includes two full days of open-ocean whale and dolphin tracking, additional scouting during the Dili–Atauro crossings, approximately 13 guided reef dives on Atauro Island, and orientation dives in Dili.
Whale sightings are never guaranteed. The itinerary is designed with dedicated safari days and flexible routing, but all wildlife encounters depend on sea conditions, animal movement and local operational guidance.
Atauro reef diving
Guided reef and wall dives on Atauro Island's pristine coral systems across multiple dive days, with flexible site selection based on conditions and visibility.
Dili orientation dives
Two relaxed orientation dives in Dili on Day 2 to check equipment, weighting and cameras before the main expedition rhythm begins.
