Amazing diving

The Bunaken National Park in North Sulawesi is a gorgeous diving hot spot in Indonesia. The water temperature is around 30 degrees Celsius, and the marine life is just super diverse.

Teaching you to teach

Simone Gerritsen

A native from Amsterdam, Simone has over 40 years of diving experience. She has been living in North Sulawesi since 1996, teaching underprivileged kids to dive, become dive guides and empower themselves through education and conservation.


Simone’s teaching is straight to the point and her methods ensure the material sticks in your head forever. She is passionate about shaping divers properly. My IDC at Thalassa was exactly what I had wished and hoped for, especially compared to my prior Divemaster course elsewhere.
