If you leave Port Arthur by ship, stay on deck with a cocktail in one hand and your camera in the other. As you sail around the southwestern tip of Tasman Peninsula, marvel at Cape Raoul’s dolerite columns. This incredible seascape was born during explosive volcanic activity in the Jurassic Period 185 million years ago. Molten cooling formed symmetrical cracks and then huge vertical columns. Some of these colossal, hexagonal pillars soar nearly 1,000 feet. If you are exploring Tasmania by car, consider driving to this tip of Cape Raoul – part of Tasman National Park – and hiking along the incredible coastal trails.
