10 Best Things to Do in the Northern Cook Islands

Almost all of the Northern Group islands are, in fact, coral atolls with a lagoon. A must-do is exploring these breathtaking seascapes by boat. Accommodation hosts and even local fishermen are happy to take visitors out onto their lagoon, visiting uninhabited motu (islets) with pristine beaches, stopping by coral banks for snorkelling, and perhaps giving you a go at fishing.

With hardly anyone else out on the water and the motu completely deserted and untouched, it will feel a world away from the lagoon cruises of Rarotonga and Aitutaki!

Location: Lagoon trips in the Northern Group are available in Pukapuka, Penrhyn, Manihiki and Rakahanga.

Manihiki is renowned in the Cook Islands and beyond as one of the world's rare producers of black pearls. A trip to the lagoon is not complete until you visit the tiny manmade islands containing pearl farms in its centre.

Experience the farmers’ interesting way of life on these tiny islands and learn about the whole process of pearl farming from start to finish. Unlike in French Polynesia, pearl farm visits in Manihiki are informal yet much more authentic.

Pearl farmers also show you how none of the oysters and their pearls go to waste.

Location: Tours can be arranged with accommodations on Manihiki. See The Complete Travel Guide to Manihiki for more information.

With limited island development, no large-scale commercial fishing, and locals relying on a healthy marine ecosystem to sustain their livelihoods, the coral reefs in the Northern Cook Islands remain unspoiled and spectacular. While some snorkelling can be enjoyed from shore, the best snorkelling spots are along coral banks within the lagoon, such as in Pukapuka.

If you're feeling brave, snorkelling in Penrhyn is usually accompanied by reef sharks, while Manihiki and Rakahanga also have plenty to explore. The only island you can't really snorkel from is Nassau. Oh, and remember to bring your own snorkelling gear to these islands!

What has otherwise been eaten to extinction on many of the other Cook Islands, coconut crabs or unga are still climbing the trees in Rakahanga!

The largest types of crabs in the world, these big blue beasts, which can live up to 60 years, can be spotted tearing off coconut husks with their huge claws. Look out for them either after dark or in the early morning.

Location: Rakahanga. See The Complete Travel Guide to Rakahanga for more information.

You know those woven white hats that all the "mamas" wear to church in the Cook Islands? That's Penrhyn! Buy gorgeous rito (bleached pandanus frond) hats, earrings, fans, shell necklaces and more straight from the talented locals than make them in Penrhyn.

You'll learn about the process and what it takes to create these incredible crafts, prized all over Rarotonga and the Cook Islands. Don't know what we're talking about? Check out the 12 Best Souvenirs from Rarotonga & the Cook Islands.

Yes, the islands of the Northern Group have taken many vessels by surprise over the centuries, with some of the "fresher" shipwrecks still visible to explore. On Nassau, the Manuvai Shipwreck is a striking sight; a Tongan container ship that wrecked in 1988, then was pushed over the reef’s edge by a cyclone shortly after.

In Pukapuka, a walk over the reef between the main island of Wale and Motu Ko reveals the remains of an old Chilean container ship.

Suwarrow is the Cook Islands' only national park and one of the most important breeding grounds for around 10 species of seabird, many of which can be seen circling the skies over the lagoon’s islands. Approximately 3% of the world’s red-tailed tropicbirds breed here, while around 9% of lesser frigate birds nest on the aptly named Gull Islands.

Suwarrow is also home to around 80,000 sooty terns. If you're lucky enough to sail to Suwarrow or stop by on the cargo ship from Rarotonga when it unloads, don't miss this sight!

Visiting the Northern Group is experiencing a slice of life in a small community on an isolated island, which can be one of the biggest gifts these islands give you.

Learn what it's like to go to school on such as small island as well as share your own stories with the local kids by visiting a school, learn about the industries such as breadfruit and taro plantation, black pearl farming, crafting and fishing, and see how communities rely on each other to survive.

Strikingly, each of the islands has its own unique culture and customs, sharing more similarities with other island nations, such as Tokelau, Samoa, and Kiribati, than it does with Rarotonga.

One of the most fascinating cultures to experience is that of the Pukapukans, who not only have their own unique language but also relocate their settlements from island to island within their lagoon, allowing nature to restore the land and make it available for future generations. Find out more in The Complete Travel Guide to Pukapuka.

One of the most striking aspects of Penrhyn is how closely the people are connected to nature. You’ll often see locals feeding and petting reef sharks that come close to shore, which you can join in too to see how friendly these typically misunderstood creatures are.

Like all of the Cook Islands, the church services are amazing to experience on a Sunday morning. Locals get dressed in their finest (usually with rito hats from Penrhyn or Rakahanga) and put on their best singing voices with harmonies that can't help but bring a tear to your eye!

Every one of the inhabited islands in the Northern Group has multiple churches, with denominations including Cook Islands Christian Church (CICC), Roman Catholic, and Seventh-day Adventists.
