Top of My List

Indonesia tops the list of best dive sites for many divers. The variety and abundance of marine life is amazing. Who doesn't enjoy diving in the reef covered with colorful hard and soft coral, sea anemone, sponge, and tunicate and watch schools of fish swirl around you?

Best of Philippines

In March 2019 we will head to the Philippines to explore the pristine beauty of the Tubbataha reef. This is a fully customized expedition to experience the best of Philippines. I'm already dreaming of jumping into the clear warm water and descending down to the reef covered with colorful soft coral.

Happy 2018!

Thank you for all your support during 2017. Looking forward to another year of great dives in 2018!
