Penrhyn (also known as Tongareva) is the northernmost Cook Island, sitting about 1,300km north of Rarotonga. It is the largest atoll in the Cook Islands by area — a large central lagoon ringed by a string of low islets — and one of the most remote. The population is small, living mainly in Omoka village.
Penrhyn has the only natural deepwater harbour in the northern Cook Islands, which historically made it a stopping point for trading ships and whalers. Today it sees very little traffic of any kind. The island is known for its fine weaving — intricate hats and baskets made from pandanus leaves are Penrhyn's most distinctive craft.
Getting to Penrhyn is genuinely difficult: Air Rarotonga runs infrequent flights when demand warrants, and the journey is long. Cargo vessels call occasionally. There is very basic accommodation. Penrhyn is for serious travellers with time and flexibility who want to experience one of the most isolated inhabited places in the Pacific.
