Our scuba diving spots in the Cook Islands.
The dive sites around Rarotonga offer conditions for every level of experience. If you'd like to go deep and explore the abyss, Rarotonga's drop-off's offer ideal conditions as the water depth surrounding the island lays between 1000 and 4000m. Rarotonga ‘s south side passages are adrenaline pumping dives with usually medium to strong currents and great fish life. The west coast has different caverns and tunnel systems which are very exciting to explore.
If you are looking for an easy and relaxing dive, the reef plateaus surrounding Rarotonga offer also a great playground with fascinating fish life and usually great visibility. The marine life around Rarotonga offers a big diversity. Apart from the smaller tropical fish species, you may also see turtles, eagle rays, reef sharks, moray eels, trevallies, napoleon maori wrasse, dogtooth tunas, barracudas, humpback whales (winter) and hammerhead sharks (winter). On a blue water dive you may even see mahi-mahi, marlin, sailfish or wahoos.
Our favourite dive sites in Rarotonga are the south and east coast passages and drop offs. However, due to prevailing south-easterly winds Rarotonga‘s south and east is often not dive-able, so please don’t be disappointed if we cannot take you there.

MV Mataora Wreck
The MV Mataora was an outer island cargo schooner that was purposely sunk on the 11th December 1990 to create an artificial reef for divers in Rarotonga. Originally 45m in length, the 300 tons vessel lays today in 10 to 18 m depth of water. After many tropical cyclones the wreck is severely broken up but the bow and stern are still recognisable today. This is a good spot for finding lion fish and the surrounding reef has some of the nicest hard coral structures on Rarotonga. Depth 10m to 25m
The northern reef stretches all along from ‚Edna’s Anchor’ in front of Trader Jacks to the‚ MV Mataora’ close to Tamarind House. It includes dive sites like Ngatipa, (Paradise Inn) and Pue. You can literally dive anywhere along that stretch and find similar conditions. Massive porites hard coral structures, usually no current and friendly fish make this a favourite dive spot on Rarotonga for introduction dives as well as a relaxing reef dives for qualified divers. Depth 10m - 28m
This site in front of Trader Jack’s has received its name from the anchor of the schooner Edna, which later sunk in Atiu. The anchor lies between two big coral bommies in 24m, which makes it perfectly clear why Edna lost its anchor. The dive follows the sand/ reef edge towards Rarotonga ‘s drop off. At about 22m, the sand starts sloping off like a ski slope. On the reef side, the bottom dramatically stops at 30m and drops down to about 65m. This is an easy deep dive with usually very clear water. Depth 12m – 40m
RMS Maitai (Wreck)
Being the most famous shipwreck in Rarotonga, this 1892 built, 3400 tons steam ship struck the reef outside Avarua Harbour on Christmas Day 1916. The engine block sticks out of the water right in front of town, and every single person coming to Avarua gets at least a glimpse of this massive vessel. After over 100 years of resting just below the surf zone, this wreck is now part of the reef. The main superstructure is still visible as well as the rudder drive shaft, various boilers and of course the engine block. The wreck is scattered over a large area and still today artefacts like old glass bottles or Ford Model-T car tyres can be found. It is the shallowest dive site on Rarotonga and can only be dived when sea conditions are extremely favourable. Depth 10m max.
Unfortunately there is no gold to be found on this dive. The site is situated in front of “The Goldmine” jewellery shop which is on the Eastern end of the Punanga Nui market. There are nice coral bommies at around 24m, which makes it a good first dive site. Depth 15m – 25m
Avatiu Drop Off
This dive site right outside Avatiu Harbour has the shortest boat ride on Rarotonga. Having a nice drop-off that starts at around 18 metres and dropping off straight into the Abyss. Fish life in the shallows is very good here and there is a good chance to see bigger predators when following the drop-off edge. Depth 12m – 40m
This site to the west of the main harbour has nice coral formations, similar to the northern reef sites. It makes for a nice, easy and relaxing dive. Depth15 - 22m
Guess where this site is located... Ascend to the surface and have a 767 flying straight over your head! Due to frequent currents, this can be a good site for eagle ray sightings in season. Big hard coral bommies and seamounts cover the bottom. Depth 18 – 26m
One of our favourites! This site has many names – Dave’s Cave, The Maze, Blackrock Tunnels, ... Being one of the shallowest sites on Rarotonga it makes it a great 2nd dive. A tunnel and cave system underneath the surf zone that stretches all along from the Runway to Black Rock. Great for spotting crayfish (lobster), lion fish and shell fish. This site can only be dived in very calm seas. Depth 10m max
A series of seamounts and coral bommies scattered over the bottom. Great swim-throughs and the bottom composition are the main features of this dive. Depth 12m – 28m
FV Maritime Reefer Wreck
This Fishing Vessel was the first ship on Rarotonga that got sunk (in 1981) to create a dive site. Like the MV Mataora, this wreck has suffered major damage by the storms. However, due to it’s depth it is somewhat better protected than the MV Mataora. Moray eels and lion fish have found their home here. Depth 20m – 30m
Sunset Lava Tubes
This is another easy second dive. A large coral shelf that rises from 18m to 5m below the surface. There is a cavern and small tunnel system with different overhead exit points to explore. Good for nudibranches and lion fish. Depth 10 – 20m
Arorangi Drop Off
A gradually sloping reef with massive coral bommies to explore. Due to frequent currents this can be a good place to find eagle rays. Depth 20m – 30m
There are different canyons and swim-throughs on the outside to explore and you may see lion fish and reef sharks. It is the smallest and shallowest of all the passages. This site has been dredged out in recent years to make it suitable for smaller vessels and cruise ship tender boats. Depth 12m
There are two large coral bommies (pinnacles) of which one is completely collapsed. A very relaxing dive inspecting the pinnacles which are occupied by soldier fish, crayfish, lion fish and eels. Don’t forget to look into the blue; you never know what might pass. Depth 20m - 30m
This boat passage can be an excellent site conditions permitting. This deepest passage on Rarotonga has narrow vertical canyon walls that start just below the surface. Visibility is usually limited to 10 to 15 metres, which adds to the passages’ natural spookiness. And together with swim-throughs and frequent strong currents it makes it a very exciting dive. Along with the other two passages on the south coast it is one of the best places on Rarotonga for turtles and whitetip reef sharks and eagle rays are frequently seen here. Not recommended for heavy breathers! Depth 20m – 29m
Rutaki Drop Off
The most impressive drop off on Rarotonga! The deeper you go, the nicer it gets...
On this site everything or nothing is possible. This is one of the best places on Rarotonga for barracudas and tunas. This is also a parrotfish mating site. Depth 20m - ?
An amazing dive for the beginner to highly experienced divers alike. The shallowest and shortest of the south-coast passages is also the prettiest. This site is usually the best place for turtles, and whitetip reef sharks are seen often. The giant resident star puffer fish seem to have fallen for this site too. Shallow, light indulged caverns and an amazing marine life make this a very special dive. Fish life is often improved by strong currents, which makes it more challenging and exciting at the same time. Depth 18m max
A very easy dive for total beginners to experienced divers. There is a cavern at about 10m and if you like to go deeper you find a resident crayfish population at around 40m. This is one of the best sites for spotting eagle rays on Rarotonga. Turtles are also frequently sighted. Depth 12m to 40m
Another one of our favourite sites! The meaning of the name is “long passage”. This site can have the strongest currents on Rarotonga, which makes it challenging yet exciting dive. Due to the current it is the best spot for reef shark sightings. From April until mid August this is one of the few spots around the island where grey reef sharks can be seen when the current is strong, sometimes in large numbers. It is also home of a resident school of eagle rays that can be over 40 in numbers. Turtles and moray eels are common here. Not recommended for heavy breathers! Depth 12m – 24m
This is another very impressive dive and one of our favourite drop-off dives in Rarotonga. Swim along a sand channel to the drop-off and into the big blue! This dive can be one of the best as you may see everything at once - sharks, eagle rays, turtles, lion fish and schooling tunas that come and check you out. Like the Rutaki drop off, this is also a parrotfish mating site. Depth 16m to 40m
A good and easy drop-off and reef dive specially when currents and visibility around the passages are not favorable. You may see pelagics patrolling the very steep drop-off. Depth 18m - 25m
You can either dive the outside of this sandy passage or dive through the passage into the lagoon. The passage itself is a good place for finding lion fish and eels. On the outskirts of the passage there are nice rock formations that can give you a feeling of being in an underwater ancient ruin. Depth 10m – 25m
A great reef dive with a steep drop-off that makes for a very interesting dive. The the reef starts to slope off at around 15 metres, making this an easy drop-off dive even for the less experienced diver. For the more experienced frog men there is a swim through at 27 metres where divers usually get greeted by a school of black trevallies that curiously circle the divers and play with their bubbles. This dive site has suffered severe damages during the cyclones 2005 but has recovered very nicely and recently has become one of our favorite spots (conditions allowing). Depth 12m - 30m
Lying just south of Matavera Point, this is a great and easy drop-off that can be dived by experienced divers and total beginners alike. Starting at 12m, this 20m long near vertical wall drops off to about 35m from whereon the bottom slopes off into the abyss. This is a good site for spotting moray eels and scorpion fish and turtles are frequently found in the shallows.The drop-off usually offers very clear water. Depth 12m – 30m
Located just north of Matavera Wall, this site can be dived on it's own as a deep dive or in conjunction with Matavera Wall. A reef plateau at around 20 metres sticks out into the blue and forms a corner where the currents meet. The top of the reef plateau is fairly barren here. Once you start getting closer to the edge of the drop-off you will see the true gem of this site: the fish life is extremely prolific here and as you start descending the vertical wall you find huge schools of fusiliers and damsel as well as many other species of reef fish. Apart for the resident school of chevron barracudas and trevallies this is a good spot to see open ocean pelagics. The drop off here is one of the most impressive drop-offs around Rarotonga as it is basically a vertical wall that keeps falling into the abyss. Due to the currents hitting the reef corner here, this site has usually exceptionally good visibility. Depth 20m - 40m
Tupapa Sand River
A sand channel with reef on both sides that starts in the surf zone and extends into the abyss. Both sides of the sand river offer unique features. The north side has a very steep wall and, when going a bit deeper, shark sightings are frequent on the south side where the reef slopes off into the abyss. Depth 18 – 35m
The dives are mainly around the FADs in the north, east and west of Rarotonga. These different Fish Aggregating Devices (FADs) have been installed around the island. They consist of floats of some kind, which are moored onto the ocean floor some hundred meters or more deep. The idea is that, by growing algae on it, these floats attract smaller fish, which then attracts the bigger predators. During a blue water dive you might see nothing but deep blue water or you might get rewarded with tunas, mahi-mahis and other open ocean pelagics. Depth 10m – 40m
