View south and west from The Onion

Tuesday 12 April: Tinderry Nature Reserve, The Onion – M/R,X. We start at the junction of the Round Flat Fire-trail and the Tinderry Road. We follow the trail for 2 km then head off-track for most of the day and visit a number of granite outcrops and slabs to the south and east of Tinderry Peak. Most of the route is exploratory and the main objective is a large slab known as The Onion. The ridges are slow going and scrubby but there are some areas of attractive old forests along the creeks. Minimum distance: 11 km with 500 metres of ascent. Map: TinderryLeader: Ian W. Transport:  124km return. Limit: 8.

8 of us drove in 2 vehicles to the Round Flat car park on Tinderry Road.

Track Notes

Ian relocated us from the top of Blue Gum Creek in Namadgi National Park, due to road closures for controlled burning. Always nice to walk in the Tinderrys.

A walk in along the Round Flat fire trail, passing the northern limit of fire a couple of years ago. At the first elbow we headed off-track, climbing NW to morning tea. 270m vertical gain through forest and granite. More climbing took us to The Onion, with a little scramble across the granite to take in huge views from south through west to north. Check out the pics and video.

We came off to the NE, down through a saddle and crossed the top of Roberts Creek. Then a climb through forest and granite to lunch.

We trended east after lunch, to ‘Groggy slabs’, huge areas of granite above Groggy Creek.

Next north to cross a swampy area at the top of Groggy Creek, then a loop to visit more granite. Some lovely old growth forest in this area.

A long leg to the south with easier walking after crossing Roberts Creek got us back to the fire trail.

A full complement of 8 making a very cohesive party. A great round from Ian again
