Diving with us

Professional, safe, knowledgeable and above all - fun!

We don’t want you to do much on your vacation. That’s why we bring your gear to the boat and set it up for you. All you need to do is double-check your setup before departure, and when everything is complete and OK, your fun day of diving can begin.

Our flexible diving trips of up to 3 dives per day and a night dive (see below), allow you to take home some amazing memories of North Sulawesi’s underwater world.

Nitrox, 15 liter tanks are available on request. We carry both DIN and International (yoke) tanks.
