Bunnings to Narrabeen lakes

Hi guys,

First time at Oxford falls last weekend. It was an excellent day. Thanks to all that have made those tracks so awesome.

We spoke to a few people there and they all mentioned a ride that can be done from near Belrose Bunnings all the way down to Narrabeen Lakes via single track for a lot of the way.

I can't see this trail marked on this website and have been looking at Google earth but can't quite discern the starting point. Is it off Kamber Rd?
Has any one got a map of this? GPX file?

thanks

Simon
