Getting started
From the middle of the tunnel at the bottom of the stairs at Mt Kuring-gai railway station, this walk follows the 'To the Great North Walk' sign through the tunnel to the Pacific Hwy. Here the walk turns left and follows the footpath between the highway and train line for about 200m to pass the traffic lights at Glenview Rd. The walk then continues straight up the ramp for another 100m and turns right onto the pedestrian bridge. Here the walk crosses the Pacific Hwy on the footbridge, then follows the concrete ramp as it zigzags back down to the ground. This ramp ends just near the Aldi shopping complex. From the bottom of the footbridge near the Aldi shopping complex, this walk follows the footpath alongside the Pacific Hwy, under the footbridge and away from the shops. Keeping the highway to your right for 100m, this walk then crosses 'Glenview Rd' (at the intersection with the Pacific Hwy) to find the top of 'Lyrebird Gully track', marked with a locked green metal gate.....

Campsite: There are 2 on route, on average they are 3.1 km apart with the largest gap of 4.7 km.

Seat: There are 3 on route, on average they are 2.4 km apart with the largest gap of 4.6 km.

Lyrebird waterfall
This informally named waterfall is found on Lyrebird Gully creek about 300m upstream of its confluence with Calna Creek. The top of the fall is partially fenced with a timber handrail where the water flows over the solid rock platform, with naturally carved holes, to fall about 8m to the shallow pool and boulders below. The track passes the top of the fall and does not provide a good view of the face of the fall, but it is still a very pleasant spot.

Lyrebird Caves
The Lyrebird caves are a series of notable sandstone overhangs on the eastern side of Lyrebird Gully. There are 3 main overhangs, with the larger (more northern) one providing significant shelter. The larger cave has a fairly flat base in the centre and provides a pleasant place to rest on a hot or rainy day.

Calna Creek Campsite (south)
This small signposted campsite sits on a flat grassy clearing in a small casuarina forest which provides plenty of shade. There is a small fireplace set up. This creek-side campsite is a good spot for those wanting to get the most out of a relaxing, overnight camp, just a short stroll to Berowra Creek and the main spine of the Great North Walk. Bring your own water, as the creek water is not suitable for drinking.

Calna Creek Campsite (north)
This is a quaint little campsite, located on the Mt Kuring-gai access track to the Great North Walk, on the banks of Calna Creek. This campsite provides plenty of room for a few tents, and also a fire scar with logs for seating. Carry in your own water as the salty creek water is not suitable for drinking.
