Muri Retreat is a small, adults-only self-catering escape on Rarotonga, offering four well-equipped apartments with lagoon views and a blissfully peaceful atmosphere.

Tucked into lush, permaculture-tended gardens, the retreat's four apartments (two kings and two queens) are each named after Cook Islands creatures and plants: "Moko" (gecko), "Onu" (turtle), "Kotei" (flower) and "Kukupa" (dove). Two rooms look out over the lagoon, and two apartments can be connected via an internal door for groups travelling together.

Every apartment comes with cooking facilities, a large fridge with freezer, microwave and a smart TV loaded with movies. There's also a saltwater pool, garden loungers and a shared community pantry area stocked with items left by fellow guests; a genuinely nice touch.

Run entirely by Simon and his wife without additional staff, the retreat has a welcoming, lived-in feel. A starter pack greets you on arrival, free laundry facilities are on hand, and all water on the property is filtered and UV treated. Airport transfers and car hire are available on request.

A short drive from Rarotonga's airport, Crown Beach Resort & Spa is the ideal retreat for a fly-and-flop getaway. Transition effortlessly to island time with each villa featuring tasteful, design-driven furniture and artwork.

Another fabulous option on the western side of Rarotonga, Castaway Resort is a resort exclusively for adult guests (except for their hugely popular restaurant), ensuring the right tone is set, at least during the day, for your Cook Islands getaway.

Only guests aged 16 and over can stay on the resort side, keeping the vibe relaxed throughout the day. With just 11 rooms, it's intimate by design.

Villas and studios are modern and inviting, if not a little compact, with self-catering options available for those who prefer it. Free WiFi is available across the property, and the resort is in the process of installing UV-treated filtered potable water, meaning guests will soon be able to drink straight from the tap (not something you can take for granted in the Pacific).

The Castaway Beach Bar is where the social side of things comes alive. The vibe is beach bar meets casual dining: relaxed, fun and unpretentious. Beer buckets, cocktail jugs and happy hour make it perfect for a long afternoon session, and free Island Night every Saturday is reason enough to plan your week around it.

Adult groups or two couples travelling together who still want the benefits of an adults-only getaway should consider Arcadia Retreat. The adults-only two-bedroom villas surround a shared lagoon-style pool nestled among the coconut palms.

Moments away are the sandy shores of Arorangi, while the Beluga Cafe is just down the road and will no doubt be your favourite coffee stop by the end of your holiday. Self-catering is an option, allowing you to enjoy a barbecue with friends or utilise your fully equipped kitchen within your colonial-style villa.

The Grand Resort is an adults-only, Vegas-inspired luxury resort unlike anything else in the Cook Islands, with 61 suites across eight room types, poolside and beachside service, and an energy that's equal parts indulgence and spectacle.

Rooms are built around a distinctive Venetian-style step-down layout, moving from the entry and bathroom through the bedroom and down into a lounge, giving each suite a sense of space that feels more penthouse than hotel room. Breakfast is included across all room types, and the large balconies are clearly designed for lingering.

The pool area sets the tone: a swim-up bar, sun lounges with cushions you can float into the water, beach cabanas and poolside service all feed into that signature Grand atmosphere.

Come evening, the IP Fountain Show lights up the pool with jets synchronised to music and lights, with shows at 7:30 pm and 9:30 pm viewable from your balcony or the rooftop Sky Bar.

Dining is covered by a café called Dolce and an indoor-outdoor restaurant with glass bifold doors.

Complimentary snorkel equipment is available for guests, and tours can be booked directly from your room via the in-room system.
