This one starts just around the corner from Leura train station (1 stop before Katoomba). You turn left leaving the station, pass through the highway exit roundabout, turn right into Britain St, then left into Mt Hay road and follow to the end. It's initially paved, then dirt road & gets progressively rougher.
It's a ~35km return trip. It's a longer distance than Narrow Neck, but the hills aren't as tough (22% at steepest). Some rough trail but not too tough to handle.
Unlike Narrow Neck there is vehicle access, so you have to watch for 4wds, but the road is rough enough they won't be going very fast. There are some corrugations but they were minor at the time we went.
What you'll see:
Of course, it looks far better when you're there. There are some great sections I didn't get photos off because I was too busy riding and looking around!
