Looking to explore the submerged landscapes that surround our beautiful islands? Then head out with our very knowledgeable marine biologist on a reef flats excursion to learn all about these curious and fascinating aquatic structures teeming with life.

Trek across the impressive reef flats that stretch to the very edges of the atolls and peer into the depths they dive into. As you make your way across the flats, keep an eye out for swooping Eagle Rays, juvenile turtles, eels and a variety of other marine creatures that call the reefs their home.

Our expert marine biologist will guide you along the reef to ensure very little damage to the structures and is happy to point out the different sea creatures and share their knowledge of these animals, the reef flats and the islands. 

Guests who would like to learn more and get more involved, can take part in an optional volunteer biodiversity survey. During the survey, you will assist in gathering baseline data of all the species found on the flats.
