A recommended diversion from the Great Ocean Road is the seven mile drive down Lighthouse Road (C157) to Cape Otway. Along the way you will encounter this ghost forest. These are dead eucalyptus viminalis. Commonly called coastal manna gum trees, they are indigenous to southeast Australia including Tasmania and can reach a height above 130 feet. But they do not stand a chance against koalas. These fuzzy, adorable Australian critters love eating eucalypt leaves, often with devastating impact on the forests.
