The Diving

Scuba diving Rarotonga is easy. Ocean temperatures range between 23°C and 28°C. Visibility averages between 20 and 30 meters when diving Rarotonga during summer time. However, it can reach a spectacular 60+ meters when scuba diving Rarotonga during the winter months. Most dive sites have little to no current. Even the more advanced dive sites in Rarotonga can be dived by the majority of divers, as long as divers follow our instructions.

All our scuba dive trips in Rarotonga are boat dives and all scuba dives are guided by one of our long term and experienced PADI dive professionals. On our scuba dive trips in Rarotonga you won’t be guided by trainees. We conduct two tank dives or single dives. We will make every effort to accommodate your Cook Islands diving requirements.

Rarotonga’s Coral Reef

Rarotonga’s reefs have stunning, healthy hard coral formations. Rarotonga is not a “big fish” destination. Nonetheless, we have reef sharks, turtles, eagle rays, giant moray eels, napoleon maori wrasse, giant trevalleys, tunas, barracuas and hammerhead sharks (in season). You may even see humpback whales, tigersharks or tahitian stingrays.

Apart for the bigger inhabitants, Rarotonga’s reefs have different types of moray eels, lionfish and scorpion fish, stone fish, flounders, as well as plenty of colourful fish of all the tropical reef fish families. Rarotonga is also home to some of the rarest tropical reef fishes in the world. The Peppermint Angelfish or Narcosis Angelfish live very deep and the best way to see these when scuba diving Rarotonga is on a mixed gas closed circuit rebreather dive (see Plongée Technique/ CCR).

Dive Group Sizes

You won’t be counting diver fins when scuba diving Rarotonga with us!
We keep our dive groups smaller than any other dive center in Rarotonga or the Cook Islands. This way we can offer you more enjoyable Cook Islands dive trip experiences and more customised scuba diving trips in Rarotonga. The maximum number of scuba divers per group is 5 plus our guide. However most of the time our dive groups are smaller. This way we can cater better for the individual needs of our divers. After all – we want to enjoy taking you out too!

Scuba Diving Rarotonga’s Best Sites

We dive Rarotonga’s best dives sites and we really dive all the sites around the island, we do not just say it. Our dive sites are on the north, south, east and west coast of Rarotonga.

We decide on the day which sites we dive. This depends mainly on sea conditions, but also on divers experience and preferences. When the wind blows from the North, the South is sheltered. As long as there is no big southerly swell, you will find us launching the boat in the South and diving Rarotonga ‘s south coast. When it blows from the South, we launch in the North and dive Rarotonga’s north coast. This way we can dive in Rarotonga most days and it keeps the boat rides short, usually between 5 and 15 minutes.

Rarotonga has around 30 dive sites and we always try to get you to different sites. You won’t get bored diving the same sites all the time, even if you are doing lots of dives with us.

Dive Bottom Times

In Rarotonga it is possible to do multilevel dives on most sites. We do not unnessessarily restrict your bottom time as long as everyone stays within table or computer limits.
Ultimately, this means that your dive time is usually only limited by your air supply and how fast you use it. 60 or 70 minute dives with us are not uncommon for experienced divers with low air comsumption, .

Site Flexibility

We are more flexible in choosing the best dive sites for the day because we keep our boat on the trailer. As we launch the boat close to the dive sites, we can access all dive sites around Rarotonga within a few miuntes boat ride. There are five boat passages (gaps in the reef) on Rarotonga. We use three of the passages regularly: Avatiu in the North (main harbour of Rarotonga), Rutaki in the South and Avana in the East.

Our Dive Boat and Safety

Our dive boat is extremely durable and stable. It is a New Zealand made custom built 5.3m Stabi-Craft aluminium pontoon boat and handles even very rough sea conditions. The vessel is equipped with two Yamaha 50 HP outboards for extra safety and power when needed. Our boat carries oxygen, first aid kit, lifejackets, flares, radio and mobile phone, as well as drinking water on all our Cook Islands dive trips.

We use back roll entries to enter the water. We take off the gear in the water before getting into the boat. This means you do not have to climb up with the gear on. We lift the gear into the boat for you. Getting back into the boat is done either over the side, or for the lazy ones, the boat has a ladder on the stern.

All our staff members are experienced and qualified skippers as well as experienced divemasters or instructors.
