Cook Islands itineraries: 1 week, 2 weeks and 3 weeks

The Cook Islands are small. The 10- and 14-day versions below add an outer island or simply slow the same route down. Every version ends on Rarotonga, because that is where the international airport is.

Days 1–4, Rarotonga. Land, collect a scooter or bus pass, and stay on one side of the island rather than moving hotels. Use the first full day for the round-island bus or a scooter loop: Avarua, the market, Muri lagoon and the Titikaveka reef. Give a second day to the cross-island walk if you are fit and the track is open, and a third to Muri lagoon, kayaking or a snorkel trip. Saturday morning at Punanga Nui market in Avarua is the social event of the week, so shift the plan if your dates allow.

Days 5–7, Aitutaki. Fly over in the morning (roughly 45–50 minutes; check schedules and fares). One day is the lagoon cruise with a motu stop, one day is Arutanga, the harbour and a scooter loop of the island, and the last morning is free before the flight back. Fly back to Rarotonga the day before your international flight if it leaves early, and sleep near the airport or in Avarua.

What to cut if you have less than 7 days: drop Aitutaki, not Rarotonga. A 4–5 night Rarotonga-only trip is a real holiday; a rushed two-island trip in 5 days is mostly airports.

Same route, more nights: Rarotonga 5, Aitutaki 4, then a final night in Avarua. The extra days buy the cross-island walk, a full Saturday market morning, a second lagoon day on Aitutaki and a buffer if a domestic flight moves.

This is the version most people should book. It keeps the two-island shape that covers most first trips, without the cost and flight risk of a third island.

Rarotonga 5 nights, Aitutaki 4, then back through Rarotonga to Atiu for 3 nights, finishing with 2 nights in Avarua. Atiu is the third island for most travellers: makatea cliffs, caves, birds and the tumunu tradition. Flights from Rarotonga run only a few times a week, so build the whole trip around those dates rather than fitting Atiu in at the end.

If Atiu flights do not line up, spend the days on Rarotonga instead: a second lagoon day, a fishing or dive trip, and a slow Sunday. Do not swap in Mangaia or Mitiaro on a two-week trip unless you have confirmed flights and are happy to lose a day each way.

Three weeks lets you stop counting islands. A workable shape: Rarotonga 8 nights split between Muri or Titikaveka and Arorangi or Avarua, Aitutaki 5 nights, Atiu 3 nights, and 2 nights back in Avarua before flying out. The remaining nights absorb weather days, dive courses or a second lagoon trip.

Beyond Aitutaki and Atiu, the outer islands — Mitiaro, Mangaia, Mauke, Palmerston and the northern atolls — are reached by infrequent domestic flights or cargo ships, with limited guesthouses. Treat them as a separate trip with confirmed transport, not as a gap-filler.

Book the international flight first, then domestic flights, then accommodation. Domestic seats are the bottleneck, and the last night must be on Rarotonga.

Money: the New Zealand dollar is used, cards work in most hotels and restaurants on Rarotonga, and cash helps on smaller islands. Budget for lagoon cruises, scooter rental and inter-island flights on top of accommodation; island nights and umukai buffets are a common add-on.

Weather: May–October is the drier, cooler window and the safest bet for lagoon days. November–April is hotter, wetter and cyclone season; build in a spare day if you travel then.

Entry: most visitors receive a 31-day visitor permit on arrival with an onward ticket and accommodation; check current rules and passport validity before booking (check).
