Some sites are located close to the track. My understanding is that the indigenous community doesn't wish the locations of cultural sites to be identified so I'm not going to be more specific.
Easy access to sites has often resulted in vandalism so I can see the point.
What are the consequences of this track being closed to climbers?
1. For four months of the year it will take an extra 30 or 40 minutes on foot to get to these climbing areas. If that's too long to walk for people then the areas could do with a break anyway.
2. For the remainder of the year it will take an extra 10 minutes on foot to get to these climbing areas. This assumes that 1 km through light bush takes about 10 minjutes to walk through.
