Tapuaetai (One Foot Island) in the Cook Islands is a tiny, idyllic islet renowned for its stunning lagoon, white-sand beaches, and the novelty of having your passport stamped. Accessibility is primarily by boat tour from Aitutaki. It is a popular spot for snorkeling and enjoying the quintessential South Pacific paradise. Guided tours are almost essential to reach the island. Costs can vary significantly depending on the tour operator and included activities, but expect to pay around $100-$200 USD per person for a full-day excursion. The duration of a visit is typically a few hours as part of a lagoon tour. The island is generally open year-round, but weather conditions may occasionally affect boat operations. Limited facilities are available on the island, so come prepared with essentials. While solo exploration is possible, the logistics and safety aspects make a guided visit much more practical.
