The Cook Islands are quite simply a paradise, many of them almost uninhabited with beautiful beaches where you can sail to spend a day basking in the sun. Go hiking on Rarotonga Island which has a dozen marked hiking trails into the mountain, where you can do some rock climbing. There are also lagoon and reef walks, so if you get tired or hot, you can simply slip into the clear, calm waters. Pony trekking to Papua Waterfall is a popular pastime and do visit the Marae Arai-Te-Tonga sacred site. You can scuba dive or snorkel alongside hump-backed whales and fish in the waters off the islands or in the lagoons. Don’t forget to buy black pearls, woodcarvings and pottery in Punanga Nui Market.
