Wollongong City Council has developed a plan of management for the Cringila hills which includes extensive bike downhill tracks.

The tracks have been drawn up and planned by outdoor group Dirt Art.

This wouldn't stop the escarpment strategy from going ahead, Cr Bradbery said, but it wouldn't include council land.

"It looks like the master plan we're putting forward for the top of Mt Keira won't include mountain biking," he said.

"The recommendation is that there are Aboriginal heritage features that need to be protected and tourism potential as well. So our [council's] little bit on top won't include mountain biking but this is our alternative proposal.

"We have been looking at that site (Cringila) for a long time as to what we can do with it. About half of it has already been activated. Unfortunately it's been used for dumping in the past."

It's understood this refers to the Mt Keira Summit Park master plan.

"That mountain biking strategy is still be worked on and negotiated, and looking at thew whole of the escarpment and where it can happen - it's not just Mt Keira in isolation," Cr Bradbery said.

"There are pretty significant Aboriginal heritage issues with Mt Keira, and that will be taken into consideration. That process is still going on.

"It depends on what the Aboriginal community are willing to allow to occur on Mt Keira. I'm not familiar with those negotiations at present.

"It's not moving away from [Mt Keira], as much as looking at how we can protect the Aboriginal heritage values. That, I think, is extremely important - respecting the input of the Aboriginal community as to what can happen, not just on Mt Keira but the escarpment ... as well as looking at where we can locate mountain biking."

Cringila Park is the home of the Wollongong Cardinals baseball team. Council's proposal includes an 11.8km network of mountain biking trails, a skills park and pump track, walking trails and picnic areas.
