Rarotonga Beaches for December

Koromiri Beach

While Muri is one of the best known and most beautiful beaches on Rarotonga, there's a stunning world of white sand just across the lagoon. You can wade to Koromiri Beach on the tiny coastal isle opposite Muri though a strong current makes either a kayak or a boat trip more advisable. Tours often stop on the island to enjoy barbecue lunches on the sand. Koromiri's stunning beauty also makes it a popular place for beach weddings.

Bars and Restaurants

Grab a quick bite at one of the on-the-go eateries at the Punanga Nui Market, linger in a garden bistro over European cuisine, or indulge in fine dining at an upscale beachfront resort. Whichever culinary adventure you desire, Rarotonga has the restaurants and bars to satisfy your craving.

Little Polynesian Restaurant & Bar

The Little Polynesian Restaurant & Bar blends island flavours with Mediterranean cuisine at the Little Polynesian Resort on the island's southern shore. The open-air eatery looks out over a stunning infinity pool that gives way to the shimmering Titikaveka Lagoon. Enjoy a bistro-style meal with a choice vintage from an array of fine wines from New Zealand and Australia. Save room for a tropical-inspired dessert. The restaurant is open daily from 7:30 am to 9 pm.

LBV - Le Bon Vivant

A popular bakery in the centre of Muri Village, LBV - Le Bon Vivant serves what some say is the best coffee on the island. They also offer some of Rarotonga's freshest baked goods. You can enjoy hearty sandwiches, gourmet pizzas and mouth-watering quiches in a garden setting or on the veranda of a restored traditional limestone structure. LBV is open daily from 7:30 am to 4 pm.

Deli-Licious Café Limited

Surrounded by swaying palms and tropical greenery in Muri, Deli-Licious Café Limited serves a range of traditional South Seas fare and western favourites.

Things to do in Rarotonga in December

Savour Seaside Cuisine      

If you're going to Rarotonga, you're going to eat. There's arguably no better place to enjoy a meal than before stunning sea views. Set just back from the island's northern shore, the Punanga Nui Market has a sizeable number of food huts with gourmet grub you can take away to any seaside location. Pick up exotic fruits, kebabs, crepes and smoothies for a picnic on the sand. You can always relax at one of the island's many beachfront cafés to dine amid a balmy sea breeze or sip a tropical cocktail before a magnificent sunset.

Leap Off a Black Rock

While the east side of the island has the most-iconic lagoons, you'll find one of Rarotonga's most-dramatic seaside locales on the west coast. Rugged volcanic rocks dot the white sands of Black Rock Beach, creating a dramatic landscape onshore and calm swimming spots offshore. The beach is a favourite with locals, especially children who love to leap from rocks into the deep calm water. With a lush backdrop of tropical greenery and a west-facing orientation, Black Rock Beach is a wonderful place to take in a magnificent sunset.

Kayak from Sunrise to Sunset

The sun plays an integral part in life on Rarotonga. Early risers on the island's east coast are rewarded with inspiring sunrises that peek over small coastal islands near Muri's shores. You can hop in a kayak and visit these tiny "motus". On Rarotonga's west coast, there's perhaps no better place to explore the sea than the Aroa Marine Reserve. While fishing, motor boats and jet skies are banned, you can take a kayak into waters that have huge numbers of tropical fish. It's a good idea to stay until dusk and enjoy stunning sunset views.

Splash at a Waterpark

One of the newest attractions on the island, Rongohiva water park welcomes you to plunge into the waters of the Avatiu Harbour. Propel down one of the largest water slides in the South Pacific. Delight as you slide and slip across a massive inflatable obstacle course. Rongohiva also offers water adventures such as banana-boat rides and speedboat tours.
