Close to being on the southernmost tip of mainland Australia, this 19m granite lighthouse dates back to 1859. It's only accessible on foot, via a 19.2km (one-way) walk from Telegraph Saddle car park, so most visitors stay overnight at the lighthouse keepers' cottages, or Roaring Meg campground, 5.2km away. Tours are available daily; contact the park office to make arrangements.
