How to Plan a Trip to the Southern Group of the Cook Islands

That's right, the Cook Islands is split into two island groups some 700km (435 miles) apart, the Northern Group and the Southern Group. The Southern Group is where most travellers visit the Cook Islands. It's home to the nation's only international airport and the idyllic holiday hotspot of Rarotonga.

But wait, there's much more to the Southern Group than the island that so many know about. There's the picture-perfect lagoon of Aitutaki, the uplifted cave-riddled eco-sanctuary of Atiu, the tiny atoll of Palmerston where everyone is "family", the uninhabited Takutea left to the birds and the turtles, and more! Discover the islands of the Southern Group, right here, in this complete travel guide to the Southern Cook Islands!

Rarotonga

Jutting out of the Pacific Ocean, dramatic volcanic mountains pierce the sky and then slope down to encircling sandy beaches. In between are the island's towns and quaint villages, which achieve the perfect blend of Western and Pacific living. Meanwhile, the resorts and boutique villas lining the beaches provide that idyllic Pacific holiday experience. This is Rarotonga.

The largest island and the capital of the Cook Islands, Rarotonga, is often believed to be the country of the Cook Islands (but as you'll find out in this travel guide to the Southern Cook Islands, there's so much more). It's the island that most travellers make it to, home to the Cook Islands' international airport, a cruise ship port of call and irresistible holiday packages.

In short, Rarotonga is one big resort, providing endless options for dining, snorkelling, watersports or just relaxing on the island that only takes 45 minutes to drive around.

Aitutaki

Often described as the most beautiful lagoon in the Pacific (and the world), Aitutaki is the second-most visited island in the Southern Cook Islands. Its azure lagoon is a highlight, dotted with motu (islands) that are pristine, uninhabited and entice all sorts of lagoon cruises.

Despite having a population of around 1,700, Aitutaki is where you start to see facilities and services start to reduce in the Cook Islands' smaller islands, providing a more tranquil experience than the "rat race" that many describe Rarotonga as.

Atiu

Atiu is one of the other Southern Group islands that is an uplifted coral atoll, characterised by its rugged limestone terrain, known locally as makatea. The traditional name of Atiu, "Enuamanu", pretty much sums up what the island is about, meaning "Land of Birds".

It's an eco-lovers paradise with a vibrant yet rare bird population, while the island's limestone caves and secluded beaches are other drawcards. The locals have their own unusual traditions that you're welcome to join in on, such as drinking "bush beer" at their local bars known as tumunu, while a boutique coffee industry on the island offers more foodie delights.

What to Do on Atiu

  • Trek through the jungle to Anatakitaki Cave (Kopeka Cave)
  • Try the local bush beer at a Tumunu
  • Do crafts, learn about Atiuan history and feast on an umu with Punarea Culture Tours
  • Taste locally grown coffee...

... And much more that we list in the 20 Best Things to Do on Atiu.

Mangaia

Mangaia is by far the oldest island in the Cook Islands and one of the oldest in the South Pacific, where the history can be felt even as you sight the terraces of makatea ringing around a central plateau when your plane comes into landing.

Exploring the ancient coral atoll is what an escape to Mangaia is all about, from the highest lookouts to deep down in the island’s caves, the latter of which hides glittering limestone and the preserved remains of Mangaian ancestors.

In between, you’ll find pockets of deserted beaches sloping into the reef and villages where locals offer generous hospitality despite the island only receiving a handful of tourists per year.

What to Do on Mangaia

  • See the glittering caves of Tuatini or Te Rua Rere
  • Climb down the cliff ladder to the hidden paradise of Ara’oa Beach
  • Hike up to Mt Rangimotia, the highest point on the island
  • Check out the Saragossa Shipwreck
  • Snorkel or reef walk at the Tuaati Rock Pools.

Mauke

An 18.4 kmÂČ (11.4 miÂČ) island with a population of less than 300, Mauke is one of the smallest of the Southern Cook Islands.

The uplifted coral atoll is rich in fertile soil, giving it the name the “Garden Island“, which is clear to see with the lush jungle bouncing from the makatea. In the fissures of the island’s makatea are various caves, typically with a refreshing pool at the bottom, while the coastal makatea is separated by pockets of serene and secluded white-sand beaches.

Although the very few that come to Mauke mainly do so for the natural splendour and tranquillity of the island, the villages harbouring its friendly locals show that there’s more to the island.

While the villages may have been divided in the past (and they have a quirky church to prove it), they are united now through vibrant yearly events and unmatched hospitality at their visitor accommodations.

What to Do on Mauke

  • Go for a swim in Vai Tango Cave
  • Swing like Tarzan on the largest banyan tree in the South Pacific
  • Bathe in a sea cave pool at Kopupooki Beach (Stomach Rock)
  • Take a Tour of “The Divided Church“
  • Relax at the beach garden and watch the sunset at Te Oneroa Beach.

Find out more about these experiences and more in the 15 Best Things to Do on Mauke.

Mitiaro

The final frontier of holidays in the Southern Cook Islands, Mitiaro is a tiny, unspoiled, and welcoming destination. The 22.3 kmÂČ (13.9 miÂČ) island has a population of around 155 residents, a significant percentage of whom open their homes to visitors, providing the only accommodation on the island.

It’s a truly traditional Cook Islands experience where you’ll dine with the locals, borrow your host’s scooter/pick-up truck and experience the villages’ weekly events.

But the friendly locals aren’t the only draw to Mitiaro, as this makatea island is awash in some of the most breathtaking swimming caves in the Cook Islands. It is also lined with pockets of beautiful and secluded beaches.

What to Do on Mitiaro

  • Jump into the deep cave pool of Vai Nauri
  • Soothe the skin in the sulphur pools of Vai Marere
  • Get the “private beach” experience at Mitiaro’s many beaches
  • Head out on a boat (or relax by) Rotoiti and Rotonui lakes
  • Take a tour to Te Pare Fort, the only fort in the Cook Islands.

More awesome ideas can be found in our 15 Best Things to Do on Mitiaro.

Palmerston

Pure white sandy islets surround an azure lagoon, and Palmerston lies far between the Southern and Northern islands of the Cook Islands. It is the final frontier for exploring the Southern Group. Unlike its sisters in the Southern Group, there is no tourism industry here; however, the 35 inhabitants are extremely welcoming to anyone who makes the effort to visit this isolated coral atoll.

It’s part of the custom for the first inhabitant to greet visitors as their host, a tradition passed down since the island was established by the forefather to whom everyone here is related.

What to Do in Palmerston

  • Visit the island's only school
  • Fish with the locals
  • Experience bosun bird hunting
  • Help with community projects
  • Experience a Sunday church service.

Takutea

A verdant uplifted atoll temptingly visible from the island of Atiu, Takutea is rarely explored except, of course, if you are a bird


This bird and turtle sanctuary is not only a physically challenging island to land on with its fully locked encircling reef but getting permission to visit here is a bureaucratic nightmare.

Nevertheless, those who are lucky enough to sight Takutea from afar will enjoy the view of its encircling seabirds and the fishing opportunities that surround it. In contrast, those with high skills can enjoy the surfing and diving opportunities.

What to Do Near Takutea

  • Enjoy watching the birds circling the island, including red-tailed tropicbirds, red-footed and brown-footed boobies, great frigates, brown and black noddies, and more.
  • Scuba dive at unspoiled coral reefs near the island.
  • Attempt the challenging surf waves off the shores.

Manuae

The two horseshoe islands, facing each other in a ringed lagoon, are collectively known as Manuae, located some 101 km (63 miles) southwest of Aitutaki. They are also some of the least-visited islands in the Cook Islands. The island to the west is Manuae, and the island to the east is known as Te Au O Tu.

The atoll is the true definition of the word; it is on the peak of a submerged volcano. However, those wishing to see this stunning piece of paradise for themselves will have to overcome many hurdles to visit this uninhabited sanctuary. That’s why it has mostly been left to the turtles and seabirds.

What to Do in Manuae

  • See the ultra-rare bristle-thighed curlew
  • Snorkel and dive among spectacular coral
  • Try fishing at these abundant yet rarely used fishing grounds.
