Follow Glory Hole Walk along the Yarrangobilly River, near Little Glory Hole Creek, and you'll come across the Glory Hole Cave. Poke around inside this cave and other nearby ones in the Kosciuszko National Park.
Glory Hole cave is less than 100,000 years old and has a high chamber with a collapsed roof which creates the large glory hole. It is one of around sixty caves in the area, four of which are open to the public.
