Essential Travel Tips
While credit cards are accepted at resorts and larger shops, cash is king for local markets and smaller vendors. Pop into an ATM at the airport upon arrival to get some New Zealand Dollars (NZD), which is the official currency. You'll find it much easier to haggle for souvenirs or grab a delicious 'ika mata' from a roadside stall with some local cash.
Renting a scooter is the absolute best way to explore Rarotonga at your own pace, but remember they drive on the left! For longer distances or if you're not comfortable on two wheels, the public bus service runs clockwise and anti-clockwise around the island. Grab a timetable from your accommodation – it's super affordable and a great way to see the island's coastline.
Embrace the 'island time' mentality and slow down! Schedules can be fluid here, so don't get stressed if things run a little late. It's considered polite to greet locals with a friendly 'Kia Orana' (hello) and a smile; a little effort goes a long way in fostering genuine connections.
Don't miss the local seafood – it's incredibly fresh! For an authentic experience, head to the Punanga Nui Market on a Saturday morning for a huge spread of local delicacies, including 'umu' (earth oven cooked food) and delicious tropical fruits. Try the 'rukau' (taro leaves) if you're feeling adventurous!
Pack light, breathable clothing, but definitely include a light rain jacket. Tropical showers can pop up quickly, especially in the afternoons, and can be quite intense. A good pair of reef-safe sunscreen and insect repellent are also essential for protecting yourself and the delicate marine environment.
The Cook Islands are incredibly safe, but it's always wise to be aware of your surroundings, especially at night. Keep valuables secure and avoid walking alone on deserted beaches after dark. Stick to well-lit areas and enjoy the peace of mind this beautiful destination offers.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When is the absolute best time to visit the Cook Islands, and what should I expect weather-wise?
For the sweet spot between sunshine and manageable humidity, aim for the dry season, from May to October. You'll get plenty of clear skies and comfortable temperatures, perfect for exploring the lagoons and beaches. While it's technically 'winter' here, think warm, pleasant days rather than anything chilly – it's paradise year-round, but this period is truly ideal.
I'm thinking of renting a scooter on Rarotonga. Is it safe and the best way to get around?
Renting a scooter is definitely the most popular and liberating way to see Rarotonga, and the main road circles the island in just about 30 kilometers. Just remember it's a tropical island, so be mindful of the occasional rain shower and the roaming chickens – they have right of way! Always wear your helmet and take it easy, especially at night.
What's the deal with currency and tipping in the Cook Islands?
The Cook Islands Dollar (CID) is pegged 1:1 with the New Zealand Dollar (NZD), so you can use NZD interchangeably. Credit cards are widely accepted in resorts and larger shops, but it's always wise to have some cash for smaller vendors, local markets, and tips. Tipping isn't customary or expected here, but if you receive exceptional service, a small token of appreciation is always welcomed.
Beyond Rarotonga, which outer island should I consider for a different experience?
If you're looking for something truly off the beaten path, Aitutaki is an absolute must-see, famous for its breathtaking turquoise lagoon. For a more remote and authentic cultural immersion, consider Atiu, known for its caves, birdlife, and strong local traditions – it feels like stepping back in time in the best possible way.
Are there any local customs or etiquette I should be aware of to show respect?
The Cook Islanders are incredibly warm and welcoming, and a simple 'Kia Orana' (hello/greetings) goes a long way. When visiting villages or attending local events, dressing modestly – covering shoulders and knees – is appreciated, especially when not at the beach. Embracing the relaxed 'island time' is key; things move at a gentler pace here, so patience and a smile are your best travel companions.
What's the best way to experience the local food scene beyond resort restaurants?
Don't miss the Punanga Nui Market in Rarotonga on a Saturday morning for an incredible array of local fruits, crafts, and delicious food stalls – try the 'ika mata' (raw fish salad). For a truly local meal, look for 'umu' feasts, which are traditional underground oven-cooked meals, often available at cultural shows or some smaller eateries. Ask your accommodation for recommendations on where the locals eat; they'll point you to the hidden gems.
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.
