The Cook Islands offer breathtaking natural beauty and vibrant Polynesian culture across its 15 islands, with Rarotonga and Aitutaki being the most visited. Rarotonga, the main island, is encircled by a coastal road and features lush mountainous terrain, secluded beaches like Muri Lagoon, and vibrant local markets. Aitutaki is renowned for its postcard-perfect lagoon, often considered one of the most beautiful in the world, ideal for snorkeling, kayaking, and romantic boat trips to uninhabited motus. For a more off-the-beaten-path experience, visitors can explore Atiu, known for its ancient caves, birdlife, and authentic cultural encounters in untouched villages.
