Diving in North Sulawesi

North Sulawesi consists of three main diving areas: the Bunaken National Marine Park on the west coast, the Bangka archipelago in the North and Lembeh Strait on the east coast. 

Despite covering an area that’s not very large, each of these areas offer entirely unique diving experiences. With access to over 150 dive sites, North Sulawesi is a fantastic place to spend your diving vacation.

With our resorts on both coasts of North Sulawesi, all areas are easily within reach.


Water temperature: between 26℃ (Lembeh) and up to 30℃ (Bunaken)

Topography: reef flats, coral walls, sand flats, pinnacles, slopes

Currents: generally mild, suitable for all skill levels

Marine life guidelines​

Don't touch, disturb or chase any marine life

We urge all of our guests to refrain from touching anything while under water. In addition, turtles should never be chased.

Do not wear gloves

Gloves can encourage unnecessary touching of (and holding on to) fragile coral. Therefore we ask our guests not to use gloves.

Maintain neutral buoyancy​

Keep a streamlined profile, stay well within the limits of your bottom time and do not go deeper than your guide.

Camouflaged creatures

A hidden stingray can end your diving holiday prematurely, so be aware of any life around you, as well as below you.
