Did you know?

Did you know that you can create an account to record, track and share your climbing ascents? Thousands of climbers are already doing this.


An amazing place for both the beginner and experienced boulderer. Short problems. Tall problems. Easy problems. Lots of problems. For the beginner who has never topped out before this is the place for you! Grab your spotter, crash pad and learn what it's like to commit to a balancy and thought provoking top out. Discover what it's like to experience fear and great achievement all at the same time! Yes my fellow boulders, you'll be KING OF THE WORLD!

By the way, if you can figure out the theme the problem names follow, might just become a healthier boulder.

Access issues inherited from Balls Head

Climbing of any kind (including bouldering) has been banned by North Sydney City Council throughout the Ball's Head Reserve since 1996. Please don't jeopardise future attempts to restore access by flouting the ban.



Directly to the right of The Bar Tenders Round. Mother Nature hasn't left much room to move around the base of this face so keep that in mind when spotting and avoid stepping on the ferns.

Ethic inherited from When Crags Collide

When Crags Collide is a bolt free environment. Bolting will not be tolerated by the developers and more than likely North Sydney Council as well.

When Crags Collide was developed as pure bouldering for the love of bouldering. The developers want it to remain this way.

It may be tempting to bolt the highballs or even put some sneaky carrots in at the top. The developers did discuss this as an option and decided seeing this is a popular look out, and the base is on a very popular hiking track, that bolts would only detract from the natural beauty of the area that non-climbers come to enjoy.

There's one rusted forgotten bolt at the top of Lindfield With A Water View from several decades ago. This is a mark oh history but if any other bolts are found here they'll be chopped by either the developers or once again, more than likely North Sydney Council.

Brendon Flanagan and Ranger Dave decided that Radka needed to continue her new found bouldering development skills. Kiddies Corner was just the start for her, so this magnificent piece of rock was left to Radkas creative mind and what a creative mind she has displayed!

This crag is a product of the great bouldering boom!
