Access issues inherited from Blue Mountains

The Blue Mountains are a World Heritage listed area. The Grose Valley, the cliffs around Katoomba and much of the Narrow Neck peninsula are part of the Blue Mountains National Park which is managed by the NPWS. The Western Escarpment - where most of the climbing is - is Crown Land managed by the BMCC. While the NPWS Plan of Management nominates several locations in the National Park where rock climbing is deemed appropriate, the majority of the climbing remains unacknowledged. To maintain access our best approach is to 'Respect Native Habitat, Tread Softly and Leave No Trace'. Do not cut flora and keep any tracks and infrastructure as minimal as possible.

Practically all crags are either in National Park or in council reserve: dog owners are reminded that dogs are not allowed in National Parks at any time and fines have been issued, while for crags on council reserve the BMCC leash law requires that dogs be on-leash.

Ethic inherited from Blue Mountains

Although sport climbing is well entrenched as the most popular form of Blueys climbing, mixed-climbing on gear and bolts has generally been the rule over the long term. Please try to use available natural gear where possible, and do not bolt cracks or potential trad climbs. If you do the bolts may be removed.

Because of the softness of Blue Mountains sandstone, bolting should only be done by those with a solid knowledge of glue-in equipping. A recent fatality serves as a reminder that this is not an area to experiment with bolting.

If you do need to top rope, please do it through your own gear as the wear on the anchors is both difficult and expensive to maintain.

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

It would be appreciated if brushing of holds becomes part of your climbing routine - do it with a soft bristled brush and never a steel brush!

The removal of vegetation - both from the cliff bases and the climbs - is not seen as beneficial to aesthetics of the environment nor to our access to it.

However, the fast growing scrub can conceal walking tracks in mere months, making remote and less popular crags slightly more difficult and fun to navigate to. Some appropriately discreet pruning is a far better alternative then track braiding (which causes far more damage).

However, do so only on Council land and definitely not in the National Park. Remember, to maintain access our best approach is to 'Respect Native Habitat, Tread Softly and Leave No Trace'. Do not cut flora and keep any tracks and infrastructure as minimal as possible or risk possible closures.

The bolted direct of The Mind Boggles remained unclimbed for well over a decade before an Italian snuck in for the sneaky send. Looks thin and blank!

Warning Fixed Gear: Top anchor

A long shady classic slab/wall on impeccable rock. This is the ringbolted orange face just right of the monster corner of Thrustblock. Bolting is a bit spaced but that's part of the rewards of a route in this style. When everything else at Porters is being hammered by arvo sun this route has blessed shade. Watch your rope length when lowering off.
