From the "dirty abandoned project" at the end of Offspring Wall walk 70m further L until you come to a collapsed roof system - This is where "Underworld" commences. If you go down the little gully to the lower tier you will find an overhanging section with three bolted mini routes on superb polished sandstone. If you continue walking thru the upper section it will bring you to a 5m long roof with an epic long boulder problem. Toward the edge of the cliff you will find anchors on a large slab that is atop the lower level. This area contains three routes.

Access issues inherited from New South Wales and ACT

If you have benefited from climbing infrastructure in NSW, please consider making a donation towards maintenance costs. The Sydney Rockclimbing Club Rebolting Fund finances the replacement of old bolts on existing climbs and the maintenance of other hardware such as fixed ropes and anchors. The SRC purchases hardware, such as bolts and glue, and distributes them to volunteer rebolters across the state of New South Wales. For more information, including donation details, visit


Walk in from Mulbring Rd and head for Kit Kat Wall and continue L along the base of the cliff.

Underworld has only recently been developed with a couple of mini sport routes and a great long bouldering problem thru a 5m roof.

Sit start at the back of the cave, and follow the line of holds arcing out to the right. Finish matched on a ledge around the lip after some cruxy moves.

Back to the upper level. This is the boulder problem under the roof that sits above Nice climb for the Kids and Little Gem. When you come the collapsed roof system and crawl thru to the other end of the cave you will come to a roof system about 1.5m above ground level. "Room with a view" starts in the back of the cave and goes all the way to the lip and finishes on the headwall.

Climb room with a view all the way to the slopey lip then bust up and left to good ledge before going straight up and up on some crimp rails before easy high terrain topping out. First done with a tied in spotter and it would be recommended.

FA: Michael Tonon, 20 Sep 2018

Start as for room with a view but halfway out exit straight left through some tough moves to reach the jugs. The a large throw to lip before heading straight up the headwall to walk off.

FA: Michael Tonon, 19 Sep 2015

Start on smooth slot at the beginning of the left hand arete. Climb the arete all the way out to finish topping out the same as Sloths in the attic.

FA: Michael Tonon, 26 Sep 2015

Start about 3m to the right of "Room with a View" matched on jug at back of cave and climb virtually directly out of the roof towards the same finish jug as "Room with a view" to finish as for this problem.

FA: Michael Tonon, 5 Apr 2016

This route is best approached by taking the vague gully (before crawling thru the collapsed roofs) down to the lower level where a nice short overhanging wall sports three routes. The first route is easiest is on the R hand side of the overhang. Two rings and anchors.

Set: paul, Jul 2015

The route 1m L of 'A Nice Climb for the Kids' Beaut sandstone up the ever steepening little wall to the anchors 3m L of previous route. Short and sweet. Easier than it looks.

Set: paul, Jul 2015

The furthest route L of the three in this mini area. Harder than its companions to the R. Open project
