Located in the South Pacific the Cook Islands is a 15 island nation with history and ties to New Zealand. That connection makes this a popular holiday destination for New Zealanders but fortunately this does not over-shadow the local Maori culture.
Rarotonga, the largest and most populated island, is the main tourist stop. Rarotonga is also the gateway to Aitutaki, it’s neighboring island, which is world renowned for its stunning lagoon and beaches.
Dry and high season start in April and go until the end of October. I went in April and it rained all day long for 6 days in a row.
With the heat and humidity don’t try to peddle bike around the island. Save time and hitchhike or take a bus which circle the island all day long.
