The Roman Baths
This is not a safe place for Children. Please be careful when accessing the Roman Baths and always tell someone where you are going. Blackhead is the most southern part of the Dunedin Volcano, a shield volcano which formed over extensions of the Titri, Akatore, and North Taieri faults between 13 and 10 million years ago. The basalt columns here are 11 million years old, dating from the early part of 3rd major eruptive phase of the volcano.
Directions
Start at the Blackhead parking lot over looking the beach. You will then have to take the trail to the beach and walk all the way along over the boulders to the left. Then the fun begins. Its time to scale the Basalt column walls around the head lands. Past what is known as the docks. I hope it's low tide. Further round and you will see. You can't miss them. A large crater type area in the columns. You are here. Remember this can only be done at low tide.
