Top Things to Do
Lagoon Exploration at Aitutaki
Embark on a boat tour across Aitutaki's legendary turquoise lagoon, a kaleidoscope of blues so vibrant it feels unreal. Snorkel amongst schools of tropical fish in crystal-clear waters and feel the soft white sand between your toes on uninhabited motus (islets).
Discovering Rarotonga's Inland Waterfalls
Hike through lush, emerald rainforests to discover hidden waterfalls like Wigmore's Waterfall or the more secluded Papua Waterfalls. The cool, refreshing plunge pools are the perfect reward after a trek, offering a tranquil escape from the coastal heat.
Avarua Market Morning Buzz
Immerse yourself in the vibrant atmosphere of the Punanga Nui Market in Avarua on a Saturday morning. Sample exotic fruits, browse local handicrafts, and enjoy the infectious rhythms of live island music – it's the heart of Rarotonga's weekend pulse.
Cultural Immersion at Te Vara Nui Village
Step back in time at Te Vara Nui Village for an authentic cultural experience, complete with traditional dance performances, captivating storytelling, and a delicious island feast. Witness ancient crafts being demonstrated and learn about the rich history of the Cook Islands.
💡 Travel Tip: For the best value on hotels during this season, check current rates on Trip.com.
Essential Travel Tips
While credit cards are accepted in larger resorts and shops, cash is king for smaller vendors, local markets, and taxis. The Cook Islands Dollar (CID) is pegged 1:1 with the New Zealand Dollar (NZD), so you can use NZD interchangeably. ATMs are available but can sometimes be unreliable, so bring a decent amount of NZD cash with you.
Rent a scooter or a small car to truly explore Rarotonga at your own pace. The main road circles the island (just 32km!), making it easy to get around. Remember, they drive on the left, and always wear your helmet – it's the law and a good idea, especially after a sunset cocktail!
Embrace the 'island time' mentality and be patient; things move at a more relaxed pace here. Dress modestly when visiting villages or attending church services – cover your shoulders and knees. A simple 'Kia Orana' (hello) goes a long way in showing respect and connecting with locals.
Don't miss the 'umu' (traditional underground oven) feast, often featured at island nights or resort buffets. For a truly local experience, head to the Punanga Nui Market on a Saturday morning for fresh fruit, delicious 'ika mata' (raw fish salad), and local snacks like 'rukau' (taro leaves).
Pack light, breathable clothing, swimwear, reef-safe sunscreen, and insect repellent. A good hat and sunglasses are essential for the strong tropical sun. Consider bringing a reusable water bottle; many resorts offer filtered water refills to reduce plastic waste.
The Cook Islands are generally very safe, but always be aware of your surroundings, especially at night. Be cautious when swimming in the ocean; pay attention to any warning flags and be mindful of currents, particularly outside of the protected lagoons. Stick to well-lit areas when walking after dark.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When's the absolute best time to visit the Cook Islands for sunshine and fewer crowds?
While the Cook Islands are lovely year-round, I'd aim for the dry season, which runs from May to October. You'll get plenty of sunshine, lower humidity, and the trade winds usually keep things pleasantly breezy. It's a sweet spot before the peak holiday season really kicks in, so you can often snag better deals and enjoy a more relaxed vibe.
How do I get around Rarotonga and Aitutaki? Is renting a car essential?
On Rarotonga, the 'Road Runner' bus circles the island in both directions, making it super easy and affordable to get around without a car. For Aitutaki, it's even simpler – scooters are the way to go for exploring the lagoon road, or you can just rely on boat tours for the best experience. Renting a car is an option, but honestly, the bus and scooter offer a more authentic and less stressful way to see these islands.
What's a common cultural faux pas I should be aware of?
The Cook Islands culture is very laid-back and friendly, but showing respect for elders and local customs is key. Always ask permission before taking photos of people, especially elders, and dress modestly when away from the beach or resort – covering your shoulders and knees is a good rule of thumb when visiting villages or churches. A simple 'Kia Orana' (hello) goes a long way!
Beyond the main beaches, are there any 'must-do' hidden gems?
Absolutely! On Rarotonga, don't miss the Cross-Island Trek – it's a bit challenging but the views from the Needle are breathtaking and you'll feel like you've earned your tropical drink. For Aitutaki, instead of just a standard lagoon cruise, look for smaller, more intimate tours that might take you to less-visited motus (islets) for a truly secluded snorkeling experience.
What's the deal with currency and tipping in the Cook Islands?
The currency is the New Zealand Dollar (NZD), and ATMs are readily available on Rarotonga and Aitutaki, though it's always wise to have some cash on hand. Tipping isn't a strong tradition here like in some other destinations; service charges are often included in bills. If you receive truly exceptional service, a small tip is appreciated but by no means expected.
Is it worth visiting during the 'wet' season (November to April)?
The 'wet' season is also the 'warm' season, so while you might encounter brief, heavy showers, they often pass quickly, leaving behind refreshed, lush scenery. It's also the time when you might see more whales migrating, and prices can be lower. If you're not deterred by the possibility of a quick downpour and want to experience the islands at a slightly different pace, it can still be a fantastic time to visit.
What is the cheapest month to visit Cook Islands?
The cheapest months to visit Cook Islands are typically Jan and Feb during the off-season. You can save 30-40% on hotels and flights compared to peak summer months. While weather may not be ideal, you'll enjoy fewer crowds and significant savings.
How many days do you need in Cook Islands?
We recommend spending 3-5 days in Cook Islands to see the main attractions without feeling rushed. This gives you time to explore the top sights, experience local culture, and take a day trip if desired. Budget travelers might do 2-3 days, while those wanting a deeper experience should plan for a week.
What should I avoid in Cook Islands?
Avoid visiting Cook Islands during Jan if possible, when weather conditions are less favorable. Also, be cautious of tourist traps in heavily visited areas - research attractions beforehand and consider booking skip-the-line tickets for popular sites.
Is Cook Islands expensive to visit?
Cook Islands can be enjoyed on various budgets. Daily costs typically range from $50-80 for budget travelers, $100-200 for mid-range visitors, and $250+ for luxury experiences. Prices are highest during Jun and lowest during off-season months. Book accommodations early to secure better rates.
What is Cook Islands famous for?
Cook Islands is famous for its unique attractions, rich culture, and memorable experiences. The destination is best known for its architectural landmarks, local cuisine, and vibrant atmosphere. Visit during Jun or Jul for the best experience.
