Diving starts here

Year-round temperatures at the 29℃ mark make diving in North Sulawesi an absolute delight. A shorty or 3mm wetsuit is all you need to enjoy one of the most diverse ecosystems in the world. 

The Coral Triangle

North Sulawesi is located at the convergence of three large bodies of water: the Pacific Ocean, the Sulawesi Sea and the Indian Ocean, forming a rich and diverse ecosystem.

150+ Dive Sites

North Sulawesi offers five unique diving areas, boasting over 150 different dive sites which are suitable for any skill level, whether you've done ten or one thousand dives.

Let's Get Wet!

If you're interested in obtaining your own scuba diving license, our PADI dive courses take you through all theory and practical skills — at your own convenient pace.

What to expect & how we work

Dive planning

Daily, our staff will confirm your dive plan for the next day — two dives, three dives, or maybe even a night dive? Want to go somewhere in particular? We will help you find other divers to go with you.

Comfy dive boats with sun roofs

Our boats have towels, coffee, tea and water on board. There's nothing like some fresh fruit after coming out of the water. Depending on the dive destination and plan, you will have lunch on board or on a beach.

Prep & carry service

Your dive equipment will be brought on board our boats in crates, and assembled by our trained crew. If you would rather do this yourself, just let us know. We rinse and dry your equipment after a day of diving.

Air-conditioned camera room

Your camera is your baby, we understand that. Our camera room is air-conditioned with plenty of space for you to set up and tinker with your shooter. On top of that, it's safe and secure.

Guided diving and snorkeling

Our dive staff is personally trained by our PADI Course Director, each and every one of them keen to show you all the natural wonders of the Bunaken National Park and the Lembeh Strait. To ensure a relaxed diving experience, we allow a maximum of 4 divers per guide.

PADI Instructors

If you're new to diving or would like to extend your skillset, we have PADI Instructors on site that will train you to the highest standards. This ensures you will leave as a well-trained diver.

Rental equipment

From a pair of fins to a full scuba set, we have everything for rent against friendly daily prices. Let us know what you need and we will take our time to fit equipment with you.

EANx / Nitrox availability

For Nitrox we blend oxygen into the air mixture using 40 liter oxygen tanks. Due of North Sulawesi's poor logistics, we cannot promise Nitrox is available 100% of the time.

Enjoy the marine environment responsibly and safely

Do not 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, despite their slow and friendly demeanor.

Maintain neutral buoyancy

Maintaining good buoyancy is key: keep an eye on your dive computer, stay within the limits of your bottom time and do not go deeper than your guide.

Do not wear gloves

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

Camouflaged creatures

Getting stung by a ray buried in the sand can end your lovely diving holiday prematurely, so be aware of any life around you, as well as below you.
