Cook Islands

The Cook Islands consist of 15 small islands scattered across more than two million square kilometres of the South Pacific, from Penrhyn in the far north to Mangaia in the south. The Cook Islands are a self‑governing state in free association with New Zealand, whose citizens hold New Zealand citizenship. The resident population is predominantly Polynesian, with Cook Islands Māori and English both recognised as official languages. For cruising yachts the Cook Islands form a convenient mid‑ocean stop on the trans‑Pacific passage between French Polynesia and destinations such as Tonga, Niue, Samoa or New Zealand.

On Rarotonga, yachts use the harbour at Avatiu on the north coast, with steep forested valleys and rugged volcanic peaks rising immediately inland.

Aitutaki is known for its shallow turquoise lagoon, boat trips to outlying sandbars, and reliable trade‑wind conditions, perfect for kitesurfing and foiling.

The more remote atolls of Suwarrow and Palmerston are well‑known optional stops for cruising yachts, but both require advance permission and have limited seasons and facilities.

Places to stay

Below are the most popular and highly rated places to stay, based on reviews from the noforeignland community:

Anchorages

	Te Tautua Anchorage ★ 5.0 Penrhyn Anchoring is feasible in sandy areas near Kura's dock, with sufficient holding against easterly winds. Visitors report easy access to the shore and friendly locals. Bommies are present, but clear spots allow for secure anchoring without needing to float chains.
	Suwarrow, Ranger Station & Check In ★ 4.8 Suwarrow Anchoring is permitted with good holding in sandy bottoms. Rangers are present and can be contacted on Channel 16 before entering. Visitors enjoy activities like snorkeling, but providing fresh produce and meat to the rangers is highly encouraged.
	Palmerston ★ 4.3 Palmerston Anchoring spots are largely on coral, with some difficulty in locating rubble and rock areas. Community engagement is highlighted positively, with assistance in anchoring and pre-arranged provisioning from nearby islands noted. It is advisable to communicate in advance for optimal support.
	Omoka Village, Penrhyn ★ 2.7 Penrhyn Anchoring is necessary for clearance, but there is no protection from prevailing winds. Visitors noted the anchorage primarily features a coral bottom, making sand scarce, yet interactions with friendly locals were a highlight.

Harbours

	Arutanga Harbour, Aitutaki ★ 3.9 Aitutaki Aitutaki Harbour presents challenges for monohulls, especially with winds above 10 knots, and mooring assistance is often needed. The channel depth varies, with most areas reported to be 4-12 feet. Visitors may need longer lines due to challenging anchoring conditions.
	Avatiu Port ★ 2.6 Rarotonga Access to Avatiu Port involves using a dinghy for shore access, which may be difficult in mild swell. The harbour has a limited capacity, only accommodating a few vessels. Staff are reported to be friendly and provide assistance with mooring.

The maritime history of the Cook Islands begins with early Polynesian voyagers who crossed the Pacific using non‑instrument navigation, guided by stars, swells, and bird and cloud patterns. These islands lay along important Polynesian voyaging routes across the central South Pacific, and many traditional stories and place names reflect this deep seafaring heritage.

Regular European contact developed from the late 16th century, and was later reinforced by the voyages of Captain James Cook in the 18th century, after whom the islands are named. During the 19th and early 20th centuries, the Cook Islands took part in regional Pacific trading networks, particularly in commodities such as copra and pearlshell, while also becoming a hub for missionaries and colonial administrators.

In the modern era, the Cook Islands have maintained a maritime culture closely linked to both Polynesian traditions and contemporary ocean travel. Rarotonga and Aitutaki, with their reef‑fringed lagoons and sheltered bays, attract inter‑island shipping, fishing vessels, and an increasing number of cruising yachts.

Today, visiting sailors encounter visible traces of this layered maritime past alongside everyday island life. Features such as the ancient Ara Metua road on Rarotonga, historic church settlements near the coast, and long‑used landing places provide tangible links between early voyaging societies, the colonial period, and the Cook Islands’ present‑day role on South Pacific cruising routes.
