Archway Islands, Wharariki Beach, South Island, New Zealand

Welcome to the Archway Islands—a group of four rock stacks at Wharariki Beach in New Zealand.

The islands are a result of wind and coastal erosion that have shaped the rocks into arches, caves and stacks.

The rocks, which are around 55–65 million years old, are made of quartz- and feldspar-rich sandstones and pebbly conglomerates.

Rising from the waters of the Tasman Sea, these rugged islets became well known around the world after they were featured in a Windows 10 desktop screensaver in 2015.

At low tide, curious wanderers can explore caves and rock pools and often spot lounging seals.
