AKA Wolgan View Canyon. AKA Nobles Canyon
Access: Easy walk, no swims or abseils but some rock scrambles.
Navigation: Navigation is fairly straight forward under normal conditions though the trail can be over grown at times.
Map: Cullen Bullen 1:25000 8931-3-N . This can be purchased at Lithgow Tourist information center or online for around $10
Time: You could probably get through and back in under an hour but why rush? Give your self a few hours to soak in the ambiance.
Being dry and fairly non technical I think The Dry Canyon is seriously underrated by “serious” canyoners but the lower constriction, particularly, is deep and narrow and relatively sustained. This is a really nice walk with nice views out over the Wolgan Valley at the end.
Follow the Glowworm tunnel road out of Lithgow. Approximately 30km along here you will come to the turn off to the Coach road. Keep to the main road (left fork) and approx 4km further on there is a small area to park your car on the left (MGA408166 on Cullen Bullen Map.) at a barricade blocking an old 4×4 trail. This is just after a narrow cutting and approximate 1km before the first tunnel.
The Walk: Go past the barricade and follow the old trail down to a small camp ground. Continue to the right and the trail leads you around some nice open scrub to a dry creek bed. Follow this down to the start of the canyon.
Where the creek drops into the start of the upper constriction (MGA403167) there is a tricky , exposed scramble down some boulders, this can be avoided by swinging up to the left and following a steep but easier trail down from higher up.
The top section of canyon is a picturesque gorge. While short and not that deep the overhanging cliff on the left is stunning.
This section soon opens up and the trail continues on, swinging a little left before entering the lower constriction. If this contained deep water it would be the most popular canyon on the Plateau. It’s deep and dark, a very nice constriction.
There are a couple of small rock scrambles to negotiate on the way through and then it opens out over the Wolgan Valley. With care you can head around to the right for better views but care is needed as the edges are loose and the cliffs exposed and you are still a long way up.
Return the way you came in.
