The Three Grottos: Atiu's Coastal Wonders

The Three Grottos are a must-see attraction on the island of Atiu, Cook Islands, offering a unique blend of coastal scenery and natural rock formations. Located near Tengatangi Village, these grottos are accessible via a reef walk at low tide or a short trail from the roadside. Despite being called the Three Grottos, there are two main crevasses/sinkholes that capture the attention of visitors. The reef walk to the grottos begins at Oneroa Beach on the southeastern side of Atiu. During low tide and calm weather, you can stroll through knee-deep, crystal-clear waters for about 30-45 minutes to reach the grottos. This perspective offers a unique way to experience the island. Alternatively, trails marked along the main road north of Oneroa Beach lead to clifftop viewpoints of the 'crevasse' grotto. Another 200m north, marked by a cross on a coconut tree, is a trail to a large circular opening in the cliffs. The grottos themselves feature crystal-clear waters perfect for swimming and photography. The vibrant marine life around the grottos also provides opportunities for snorkeling and observing the underwater world. The surrounding lush greenery enhances the sense of tranquility and connection with nature. As the sun sets, the grottos take on a magical quality, creating unforgettable memories.
