A lovely walk around Bundanoon is the "Bridge to bridge", about 5km in length (or 4 if you use the railway crossing at the station). Be careful of traffic on the Northern end of Bundanoon road, but otherwise enjoy the village.
This cache is next to the famous Bundanoon Burrowing Koala. I had a cache here years ago, but it was muggled. Hopefully this one hangs about a bit longer - you don't need to go over the fence, and you're looking for a black bison.
