11 Best Nature & Wildlife Tours in Rarotonga & the Cook Islands

A guided tour of Maire Nui Gardens is one of the most intimate and genuinely enriching experiences on Rarotonga, taking you through seven acres of 100% organic gardens with a knowledgeable guide and no more than 11 other guests for company.

Over the course of an hour, the guided tour takes you past lily ponds, footbridges, native and introduced plant species, local fruit trees and food gardens, all on easy, mostly flat terrain. As you go, your guide shares the living history of this remarkable piece of land, title land passed down through generations from the ariki (chief) to her daughter, and now lovingly maintained by the mother who owns and runs the gardens today.

You'll taste fresh herbs, medicinal plants and seasonal fruits along the way, and see the composting systems that keep the whole property running without a single spray, chemical or pesticide.

The tour finishes at the Maire Nui Gardens Café, where a fresh organic tea is included. If you're in no hurry (and why would you be?), stay on for lunch: the menu features the "Tropical Salad", "Garden Tacos" and the legendary "Famous Lemon Meringue Cheesecake".

Self-guided visits are also available for a small entry fee, open from 9 am to 5 pm, Monday to Sunday. Note that the cafe is only open on weekdays.

Take a nature tour inland with Maunga Tours where you won't just do the famous Cross-Island Track, you'll get more out of the journey with a hands-on nature experience. The 3-4-hour hike includes hiking to the summit of Te Rua Manga, a.k.a “The Needle“.

You’ll be shown all sorts of unique flora and fauna that are otherwise easy to miss if you were hiking on your own. The hike ends at the Papua Waterfall, where you can wash off your hard work. A tropical lunch with fresh fruit is also included.

Another way to experience the marine wildlife of the Cook Islands is on one of its many lagoon cruises, some of the best of which are in the Aitutaki Lagoon.

With a focus on ecology and conservation, Teking Lagoon Cruises offers a boutique, small-group experience that sets itself apart from the larger cruise-style tours on the lagoon.

Their flagship "Small Group Snorkelling Tour" is a full-day, lagoon-focused adventure with a maximum of 24 passengers, allowing the boats to reach corners of the lagoon that larger vessels simply can't access. Expect pristine snorkelling spots, visits to four motu (islands) and a fresh barbecue-style lunch on a private island stop.

The day is built around the lagoon itself; the marine life, the history, the conservation work and, of course, the famous fish feeding spot.

The experience is intentionally more active and intimate than a cruise-style tour. Families are welcome, with child and infant rates available, and private charters and a sunset cruise are also on offer.

Rarotonga Turtle Tours offers one of the most ethical and mindful turtle tours on the Avaavaroa Passage.

They take small groups of no more than six guests to snorkel alongside green turtles and eagle rays.

After a safety briefing on how to swim respectfully with turtles, you'll board a boat to either the popular Avaavaroa Passage or the quieter Papua Passage (on request), where the shallows quickly drop into a deeper channel teeming with marine life.

Turtles can be spotted resting under rocks, scratching their backs and feeding on algae as it drifts through the passage, and the guides know exactly where to position you so the animals come to you naturally.

Keep an eye out for schools of eagle rays too; the guides know the spots where they surface for those unmissable photos. The crew, led by Kato, Kali and the team, will also handle underwater photography throughout.

Included in the "Turtle and Eagle Ray Tour" are quality masks (no fogging here!), snorkels, fins and booties, light refreshments, and Surf Lifesaving and First Aid-certified guides for 1 hr 30 mins of in-water time. Longer and custom private tours of Avaavaroa Passage are available, as is a guided free dive in Papua Passage, which features an underwater cave.
