Wondering what this is all about? If you haven't already heard, this is what one would call a sunken garden! The sinkhole was once a cave, its limestone roof collapsed and then James Umpherston saw this as an opportunity to make his mark. In 1886, he converted this place into a massive garden where little possum families dominate the areas. Don't worry, you can visit without being treated as an intruder, these creatures only come out at dusk. The beautifully landscaped garden is can be entered through hidden stairways and paths leading to it. You'll see lovely fountains, ferns and vibrant flowers that make the place seem as magical as ever.
