Extinct volcano 15km south of Mt Gambier. Steep 20 min walk up to rim then an easy stroll around
the crater. Walk to the bottom if you feel energetic.
Those who fear heights or suffer vertigo may not like the rim walk. Proceeding clockwise looks OK but before you start look at how you will be returning - clambering over rocks to get back to your start point. It's especially precarious if it is windy.
