Saturday 20 January 2024: A dawn sortie up Billy Billy Rocks – S/R. We’ll be making an early start to drive out along the Corin Dam Rd and parking at the base of the rock climbers track up the Rocks. The old track was burnt in 2019 but the going is reasonable. Late breakfast/ morning tea greeting the morning looking out at the mountains.


From Garmin Connect (MAP66i) – Distance: 6.15km | Climb: 365vm (Elev Corrections Enabled) | Time: 2:06 moving + 2:52 of stops = 4:58 | Grading: S/R; M(10).

Trip Report

I was last on Billy Billy Rocks on 29 Jun 19. That’s not to say that I got to the top then. The times I’ve been to the top have been led by others, on 22 Sep 18, 21 Nov 17 (with help from Jenny H), 14 May 16, 26 Jul 14, 30 Jan 10 (not to the top), 12 Jan 08.

Both Dick and I suffer from the same problem – we can’t get to the top without someone else showing us the way. So Rob H kindly put this trip on. Dick has a great follow on – he’ll pop back soon to review the route, then put on a CBC trip himself. Me? I’m getting too old for this, so will probably book on Dick’s trip!

Today Rob didn’t bring his handy rope ladder (but he did have a rope in his pack, just in case). We were to try a slightly different route from the bottom of the Rocks, Peter Conroy’s ‘crawls’.

Walking from the verge of Corin Road at 7.15am. A bit up the washed-out old fire trail, then left onto the rock climbers’ route.

The route/pad has worn back in again nicely. It’s also well marked with cairns and tapes.

Easy to follow pad at 1310m

A water break at a slab. The tree trunk made a handy seat coming out.

A quick break on a somewhat horizontal slab

Plenty of tapes, at least up to Billy Billy Creek.

Another brief stop at a granite slab, which makes a good map spot when doing this walk as a round coming back down the spur from Bogong Cave.

The pad drops down to Billy Billy Creek.

An expansive patch of wildflowers in the sphagnum by the creek, kindly identified by Ciaran via NatureMapr as Geranium neglectum (Red-stemmed Cranesbill). Great service!

Billy Billy Creek was running freely.

The tapes were few and far between climbing out the NW (true left) side of the creek and the fine footpad changed to one a little more difficult to follow in the grassy ground cover. But the tapes were reestablished closer to the top of the climb.

We reached the Bily Billy Rocks area at the 1400m contour and followed the route to the SW along the base. Arrived at waypoint ‘Cairn 1 – Billy Billy Rocks’ at 8.50am.

As noted above, a slightly different route to the top was used today, involving a couple of crawls.

We winkled our way up through the tors.

The second crawl was a bit tighter.

The final crawl had us out on the bottom of the final run up to the top.

A scurry up and we were there.

What a great place!

We enjoyed morning tea and the views.

At last Rob had to say “mush, mush” and we began the reverse down.

But Dick and Lena had a surprise for us when we got down from the very top tors.

Cairn and clearing where we turned left to R&L’s slot

It was a lovely squeezy passageway.

We dropped our packs and sidled through as far as we could. It was definitely one-way traffic towards the end.

There’s several more photos in the album, if you want a further idea of what it was like.

We backed out, backed down, and returned most satisfied to the Corin Road.

Thanks heaps, Rob and Jen. Everyone had a grand time!


8 walkers – Michael C, Jenny and Rob H, Mon H, Dick M, Lena O, Sandra T, me.
