Tunnel Beach is a stunning spot near Dunedin with high cliffs, rock arches, and a hidden sandy beach. You reach it by walking down a track from the car park through farmland and along the cliff edge. At low tide, you can explore the beach and see the tunnel carved through the rock, which was made by a wealthy family in the 1800s. The dramatic cliffs and waves make it a fantastic place for photos, especially when the sun is low and the light hits the rock formations.
