With clear lagoons, lush peaks, and a culture steeped in storytelling and music, the Cook Islands holidays are a dream for anyone craving both relaxation and a touch of adrenaline. While the beaches are as tranquil as they come, the real magic lies in stepping beyond the shoreline.

Whether you're diving deep, paddling out or hiking high, adventure here is wrapped in beauty at every turn.

Snorkel the Coral Gardens in Aitutaki

Aitutaki’s lagoon is often described as the bluest in the world. Glide over coral gardens teeming with tropical fish in water so clear you’ll feel like you’re floating in glass. It’s a peaceful way to connect with the island’s underwater life, with plenty of shallow spots perfect for beginners.

Take a Traditional Vaka Cruise

One of the best ways to explore Aitutaki’s motus is aboard a traditional vaka. These handcrafted double-hulled canoes are still used today for cultural tours, giving you a chance to learn from local guides, visit uninhabited islands and enjoy fresh tropical meals on the water.

Dive the Shipwrecks of Rarotonga

For certified divers, Rarotonga’s underwater world offers something unique. Beyond the reefs lie several shipwrecks where coral has taken hold and marine life thrives. Moray eels, turtles and reef sharks are often seen circling the wrecks, making for an eerie yet mesmerising dive.

Hike the Cross-Island Track

If you’re up for a land-based challenge, the Cross-Island Track delivers. This trek takes you through dense jungle, past waterfalls, and over ridgelines with views of the entire island. The climb to Te Rua Manga (The Needle) is steep in parts but offers a rewarding panorama for those who make it to the top.

Kayak to Moturakau

This tiny islet in the Aitutaki lagoon feels like something from a movie set. Accessible only by kayak, it’s a favourite among travellers looking to get off the grid. Paddle through calm turquoise waters, stop for a snorkel along the way, and enjoy a picnic in complete solitude.

Night Paddleboarding on a Glowing Lagoon

When the sun sets in Rarotonga, some lagoons come alive in a new way. Night paddleboarding with LED-lit boards gives you a glowing view of marine life below. It’s calm, surreal and best enjoyed under a star-filled sky.

Go Whale Watching in Season

From July to October, humpback whales visit the waters around the Cook Islands to mate and give birth. Spotting one breach in the distance is unforgettable. Tours led by experienced guides offer respectful viewing opportunities while sharing insights into these giants’ migration journey.

Explore the Underground Caves of Atiu

Atiu, often overlooked by travellers, is home to limestone caves formed over thousands of years. Local guides lead small groups through the narrow passages, where you’ll see stalactites, underground pools and even encounter the rare kopeka bird that nests in total darkness.

Try Kite Surfing in Muri Lagoon

Steady trade winds and warm, shallow waters make Muri Lagoon a top spot for kite surfing. Whether you’re a beginner or experienced rider, the conditions here are near perfect. Lessons and rentals are available, with instructors helping you find your rhythm with the wind.

Swim with Giant Trevally

On guided tours from Aitutaki, you can snorkel in areas where giant trevally gather. These powerful fish can reach impressive sizes and are incredibly fast. Watching them dart through the water is both thrilling and humbling.
