The sunrise was spectacular as it rose over the Island and hit our boat with perfect morning light. While I am busy taking photos of the moment, fellow divers join me on the upper deck with coffee.

Yesterday, I was nervous but today I only feel excited to go diving again in this biodiversity rich spot.

Our first dive of the day is absolutely breathtaking despite it’s name – Dirty Rock.

Dirty Rock, Cocos Island, Costa Rica.

From the moment my mask is underwater I know this is going to be something I will always remember. I catch my first glimpse of a hammerhead shark, while some of the other divers are treated to a view of five sharks circling together!
