Rarotonga Island. Cook Island. Polynesia. South Pacific Ocean. The big fish, Diving Centre in Rarotonga. You can dive Rarotonga in clear, warm waters with fantastic visibility and diversity of marine life which makes it excellent for diving and snorkelling or if you've never been diving before - we are a full service dive operation who can cater for all your needs and take you out for your first bubbles in a breath taking under water world. Either if you explore the abundant fish variety of the lagoon right across the road in the Aroa Marine Reserve as a snorkeler/diver or if you take a trip outside the reef you will feel the difference that Rarotonga and The Big Fish has to offer. If you are diving with us, we guarantee you a personalised, relaxed atmosphere. We have time for our guests, either if you just rent equipment, do your dive course, a dive trip or just pop in for a coffee. Most of our guests come into our shop as customers and leave as friends - hopefully with great memories of scuba diving the cook islands with The Big Fish.
