Experience Blackwater diving in Rarotonga

Blackwater diving in Rarotonga

Scuba dive Rarotonga at night in the deep, open ocean. Witness the largest migration of biomass on our planet with Adventure Cook Islands blackwater diving trips in Rarotonga.

Imagine you are in the middle of the ocean, with 1000 to 2000 metres of water below you. It is a pitch black night, there is no moon, no wind and the the ocean surface is flat. Only a weighted line with attached lights illuminates the water. As you dive down, you see that you are surrounded by countless of tiny critters. You are observing the largest migration of biomass in the world: the diel vertical migration. This is blackwater diving. Nowhere else in the world will you feel as close to being in outer space.

The diel vertical migration

During the diel (or diurnal) vertical migration, millions of tiny creatures called zooplankton migrate every night in the cover of darkness from the deep oceans up towards the surface. At the surface, these miniature crustaceans and jellyfish feed on the phytoplankton, which are microscopic size plants. At the end of the night, the zooplankton must make their way back to the safety of the dark, deep ocean to avoid being eaten. During this ever repeating synchronized movement through the water column, the zooplankton is followed by a large number of predators that feed on this seemingly endless food source.

Mystery Shipwreck in Rarotonga Identified

Letter R on stern of shipwreck

The mystery of the new found shipwreck in Rarotonga has been revealed.

In February 2018, Carina and Patrick discovered a small shipwreck in Rarotonga. The vessel was a sailing yacht that lay in 70 metres of water depth outside Avatiu. After talking to many locals and multiple dives on the wreck, the identity of the shipwreck remained a mistery. The only clue to the identity of the vessel was a big letter “R” in the centre of the stern of the vessel.

The breakthrough came recently, after Patrick talked to the Director of Maritime, Ngatokorua Ngatokorua (Junior). After hearing the story and seeing images of the wreck, he also confirmed that Maritime Cook Islands have no records about the existence of such wreck. However, he assured Patrick to try to find out more information on his end.

Scooter helmet law changes for Rarotonga

Helmets now compulsory for all in Rarotonga

The Cook Islands government has recently amended the safety regulations one more time.

In recent years, and after much debate within the Rarotongan community, the Cook Islands government had already made wearing safety motorcycle helmets mandatory for all visitors as well as younger riders on Rarotonga. As it did not include most local residents, this law had caused some confusion. Some visitors could not understand why they had to wear a safety helmet on Rarotonga when many other riders didn’t.

This year the government has made more amendments to the act. It is now mandatory for every person riding on a scooter or motorcycle on Rarotonga to wear an approved motorcycle safety helmet. This includes any pillion (passenger), no matter whether the pillion is a child or adult.

Helmets not mandatory in outer islands

The traffic on the outer Cook Islands is not comparable to Rarotonga. Furthermore, people ride way faster on Rarotonga than they do in the outer islands. Therefore, the changes to the safety helmet regulations are only for Rarotonga, not for the outer islands.

COVID-19 update

COVID19-Update

Cook Islands declared COVID-19 Free Zone

2020 has been an exceptional year in many ways. With the virus spreading and life being turned upside down in most parts of the world, the Cook Islands have managed to stay Covid-19 free until today. With Cook Islands borders being closed for visitors since April, the nation’s tourism industry sector is eagerly anticipating the return of visitors in the near future.

Having said that, we acknowledge there will be a constant risk of the virus spreading over to our little paradise once borders re-open.

As such, we take the health and well being of you, our customers and our staff very seriously. We will be following the Cook Islands Ministry of Health, CookSafe and the dive industry guidelines for contact tracing and equipment sanitisation.

We would like to assure all our customers that it will be business as usual and all our dive activities as well as rental and sales operations will go ahead as per normal. However, we will do everything possible to keep you and our staff safe over this Covid-19 period – and beyond.

Crown-Of-Thorns Removal

Crown-O-Thorns starfish

Crown-of-thorns starfish eradication on Rarotonga

You got to to love the diving in Rarotonga! Great visibility and warm water combined with our fascinating marine life makes scuba diving in Rarotonga extremely fun and explains why many divers keep coming back year after year.

Crown-of-thorns starfish suckers and spines
Crown-of-thorns are beautiful starfish

Amongst our natural reef inhabitants are the beautiful Crown-of-thorns starfish, aka COTS and locally known as taramea.
COTS are natural reef predators and have evolved over millions of years. These starfish have thousands of suckers and venomous spines. Crown-of-thorns starfish are feeding on coral and are important for the natural growth and health of the coral reefs. Their preferred food are fast growing corals. By primarily feeding on fast growing corals they make space for the slower growing, reef building corals, which in turn is important for the healthy growing of the coral reef.
