Do

• Avarua (Rarotonga · main town): The small, friendly capital with its harbour, market, cafés and historic mission buildings.
• Muri Beach (Rarotonga · lagoon): The island's most popular stretch, with shallow turquoise water and small motu islands to swim or paddle to.
• Te Rua Manga (The Needle) (Rarotonga · hiking): A dramatic volcanic spire at the heart of the island's best-known jungle trail.
• Aitutaki (Southern group · lagoon): A triangle-shaped lagoon of extraordinary colours, ringed by uninhabited islets and white sandbars.
• One Foot Island (Tapuaetai) (Aitutaki · sandbar): A postcard-perfect motu where you can wade across sandbanks in impossibly clear water.
• Atiu (Southern group · caves & birds): A raised coral island with forests, caves, coffee growing and a strong traditional culture.
• Mangaia (Southern group · geology): One of the Pacific's oldest islands, ringed by fossilised coral cliffs and quiet taro valleys.
• Mauke (Southern group · off the beaten path): A tiny, gentle island of swimming caves, a unique divided church and almost no tourists.

Things to do

• Snorkel Muri Lagoon. Float over coral heads and giant clams in the calm, glassy lagoon on Rarotonga's southeast coast.
• Hike the Cross-Island Track. Climb through jungle to the base of Te Rua Manga, the Needle, for sweeping views of Rarotonga's peaks and reef.
• Cruise Aitutaki's lagoon. Sail across one of the Pacific's most beautiful lagoons to the dazzling sandbars of One Foot Island.
• Shop the Punanga Nui Market. Join locals on Saturday morning in Avarua for island food, crafts, black pearls and live music.
• Hear a Sunday church choir. Attend a service at a historic coral-lime church to hear soaring Cook Islands Māori hymn singing.
• Watch an island night. Feast on local dishes and watch thrilling drum dancing at a traditional island night show.
• Explore Atiu's caves. Crawl through limestone caves where kopeka swiftlets echolocate in the dark.
• Ride the round-island bus. Circle Rarotonga on the clockwise and anticlockwise buses, hopping off at whichever beach looks best.
