The Natural Arch is believed to have been formed from a cave after an earthquake more than 2 million years ago. Its shape has changed over the centuries due to rain and wind erosion. The arch measures some 200 metres high and can be located at the eastern side of the island. Visitors walking to the arch can see other natural wonders along the way. There are lots of benches sited along the pathway where you can sit and gaze out at the views.
