Responsible Tourism


Think Globally. Act Locally!

At Big Blue Diving, we strive to be ecologically-minded in every way possible. We understand the fragility of our island and that it is a paradise with limited resources. Through numerous projects and initiatives, we work closely with the local community to sustain our local economy and protect our island from the impact of tourism. By choosing to dive with Big Blue Diving, you contribute to our ecological mission while enjoying the best diving environment on the island.

As a small island with an economy dependant on tourism, we understand that there are many restrictions to living a completely ecologically-friendly life. We endeavour to be an eco-minded resort where possible, such as appropriately managing our waste and reducing our water and electrical consumption. As part of the island community, we aim to contribute to Koh Tao’s value by providing income and the financial incentive to protect the area’s natural environments and local communities through buying locally sourced produce.

Big Blue Diving is a unique dive school because we actively contribute to worldwide coral reef research. We have had the privilege to assist internationally renowned marine scientists and masters students conducting field research such as diver-related reef damage, the impact of discarded nets on our reefs, and the recovery of corals from mass bleaching events. We are the first dive school on Koh Tao to have a team dedicated to this scientific research, which is essential to formulating the policies and guidelines required to protect our reefs for future generations to enjoy. You can see a list of our publications here.

We strongly believe that communication and sharing of information is the key to the worldwide conservation of our reefs. If you would like to know more about how to make your resort more ecologically-friendly or more about how to implement marine conservation projects such as a coral nursery construction and reef health monitoring projects, please contact us at

Although the island remoteness is one of Koh Tao’s many charms, it does hinder some of our conservation efforts. We aim to be as eco-friendly as possible, but our best intentions cannot always overcome the reality of some situations. To achieve the best results, we work closely with local communities and are regularly adapting our policies to shifts in local rules, laws, and culture, in order to try to have a positive effect on our local ecosystem. We are always open to suggestions, so if you have any suggestions for improving our policies, please feel free to contact us at
