How we run the trip
This trip stays small on purpose. We keep the group limited, use a local boat, and make decisions based on the sea, the whales and the conditions on the day.
Guidelines first
No chasing, no touching, no crossing paths. We position ahead and wait.
Fit-check before confirmation
We confirm only if expectations and safety match. That protects you, the whales and the crew.

Timor Leste sits in the Coral Triangle, which is one of the richest marine regions in the world. Encounters vary, but blue whales are not the only animals to watch for.
What else can appear?
- Whale sharks

Some surveys around Timor Leste (e.g., Atauro area) have even been described as among the most biodiverse reef waters recorded — which matches what you feel out there.

Timor Leste blue whale FAQ
Straight answers for travelers who want the in-water blue whale experience in Timor Leste, East Timor or the Dili and Atauro channel.
October and November are the key months for our private blue whale trips in Timor Leste, also searched as East Timor. The broader migration window can begin around September, but October and November are the strongest months for planning.
Yes. That is what this private blue whale swimming trip is built around: a calm, respectful in-water experience with blue whales. We use the boat time to read the situation and get into position.
The trip is clearly planned around the in-water experience. In season, conditions are usually very good for it; we take time to read the whales calmly and get into the right position.
The trip is based around Dili and the deep channel between Dili and Atauro. This area is important during the pygmy blue whale migration and is the practical base for our private boat days.
It is both. We start with whale watching from the boat to find and read the whales. If behavior, visibility, swell and local rules allow it, we attempt a calm blue whale snorkeling or freediving entry.
Yes. The main focus is the in-water experience. Watching from the boat is how we find the right moment and position, not the goal by itself.
No certification is required, but you should be calm and confident in open water. This is not a beginner pool experience. Comfort in the ocean matters more than performance.
Your booking is private for your group, with a maximum of five guests. We do not add strangers to fill the boat.
More days give you more chances because ocean conditions change. You can request one to five days. If seeing or swimming with blue whales is a major goal, several days are usually more sensible than one.
Included are the private local boat for your group, local crew, fuel, safety briefing, underwater guide, drinking water, lunch, and mask, snorkel and fins. Weight belts and weights are available on request for experienced freedivers. We do not provide wetsuits, and one is not needed for the standard snorkeling experience. Flights, accommodation and insurance are not included.
We watch from the boat first to read direction, speed and calmness. That is preparation for the entry, not the main goal by itself.
