Five of us went up Mount Greville yesterday. We ascended via the South East Ridge and came down via the Waterfall Gorge. Stunning views, particularly from about halfway down the Waterfall Gorge path where there were open rock faces you can walk on top of and stare out at Lake Moogerah. It took us about 4 hours with plenty of stops. The views from the actual summit were so so but everything else made up for it. I will be back to try Palm Gorge next time (up) and probably South East Ridge down for those views.
