Essential Travel Tips
While credit cards are accepted in larger resorts and shops, cash is king for smaller vendors, markets, and local eateries. Exchange some currency at the airport upon arrival, but also look for ATMs in Avarua on Rarotonga for potentially better rates. Having a mix of NZD cash will make spontaneous purchases much easier.
Rent a scooter or a small car to truly explore Rarotonga at your own pace. The main road circles the island, making it easy to navigate, and it's the best way to discover hidden beaches and local cafes. Remember to wear your helmet and drive on the left – locals are generally relaxed, but it's still a public road!
Embrace the 'island time' mentality and be patient; things move at a slower pace here. Don't be afraid to strike up conversations with locals – they're incredibly friendly and happy to share insights. Attending a Sunday church service is a beautiful cultural experience, just dress respectfully in modest attire.
Don't miss the 'umu' (traditional underground oven) feast if you get the chance, often featured at cultural nights or resorts. For a more casual bite, try the 'Ika Mata' (raw fish salad) at local spots like the Muri Night Market – it's incredibly fresh and delicious. Grab some tropical fruits from roadside stalls; they're usually cheaper and tastier than in shops.
Pack light, breathable clothing, plenty of reef-safe sunscreen, and a good hat. You'll live in swimwear, but also bring a light rain jacket as tropical showers can pop up quickly. Don't forget insect repellent, especially for evenings, and a reusable water bottle to stay hydrated and reduce plastic waste.
The Cook Islands are very safe, but it's always wise to be aware of your surroundings, especially after dark. Keep valuables secure and don't leave them unattended on the beach. The biggest 'hazard' is probably sunburn, so slather on that sunscreen and stay hydrated!
💡 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 if I want perfect weather and fewer crowds?
Honestly, aim for the shoulder seasons: May, June, September, and October. You'll catch the tail end of the dry season with gorgeous sunshine and lower humidity, but the peak season crowds have thinned out. It's that sweet spot where you get the best of both worlds – fantastic weather without feeling like you're sharing the beach with everyone.
I've heard about the 'Island Night' cultural performances. Are they worth it, and how do I find an authentic one?
Absolutely! 'Island Night' is a must-do for a taste of Polynesian culture, featuring traditional music, dancing, and a delicious buffet. Look for ones hosted by your resort or a reputable local tour operator; they're usually well-organized and showcase genuine local talent. Don't be shy to clap along or even try a few dance steps if you're invited – the locals love it!
Getting around Rarotonga seems easy enough, but what about Aitutaki? Do I need to rent a scooter everywhere?
On Rarotonga, renting a scooter or car is definitely the way to go for maximum freedom. However, Aitutaki is much smaller and more laid-back. While you can rent scooters, many visitors find they can explore the main island by bicycle or even by walking to nearby spots. For the iconic lagoon tour, you'll be on a boat anyway, so don't stress too much about transport on land.
Beyond the famous Aitutaki lagoon, are there any lesser-known spots or activities that locals rave about?
Definitely explore the 'back road' on Rarotonga – it's less developed and offers a glimpse into local village life away from the main coastal road. On Aitutaki, ask about visiting the tiny island of Akaiami; it's incredibly picturesque and feels like stepping back in time. Also, don't miss trying 'ika mata' (raw fish salad) from a local roadside stall – it's a true taste of the islands.
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 in Rarotonga and Aitutaki, though it's always wise to have some cash on hand. Tipping isn't customary or expected here; service charges are usually included in prices. A genuine 'kia orana' (hello) and a smile go a lot further than a tip!
I'm a bit nervous about the tropical sun. What are your best tips for staying safe and comfortable?
The sun here is no joke, even on cloudy days! Always wear reef-safe sunscreen with a high SPF, a wide-brimmed hat, and sunglasses. I always carry a light, long-sleeved rash guard for swimming – it makes a huge difference in preventing sunburn during extended snorkeling or beach time. Stay hydrated by drinking plenty of water throughout the day.
