The lagoon encompasses numerous small islets, or motus, set against a triangular barrier reef roughly 12 kilometers in length. Its unique geography, combining volcanic highlands with coral islets, creates a diverse ecosystem supporting tropical fruits, vegetables, and rich marine life. The lagoon is a major tourist attraction, offering stunning scenery, boating access through reef passages, and opportunities for snorkeling and diving. The nearby main village of Arutanga provides access to the lagoon and is home to the oldest church in the Cook Islands, reflecting the island's historical significance.
