Located along the Otago coast, the Moeraki Boulders are one of the most fascinating and popular attractions on New Zealand’s South Island. The large spherical objects are concretions that started forming some 60 million years ago from seafloor sediment and have been exposed through shoreline erosion. There are more than 50 boulders along the beach, with the largest ones measuring up to 3 m across and weighing over 7 tons. The boulders present stunning photo-opportunities, especially at sunrise and sunset.
