Reached by a relatively short bushwalk (1.4km return), Walls Lookout offers one of the most spectacular vantage points that you can get from the Bells Line of Road. (You get similar views and probably a few less people from Rigby Hill, which is also reached from the Pierces Pass carpark off the Bells Line of Road.) The lookout was named in 1917 after James Tomas Wall (1870-1943), the President of the Blue Mountains Shire Council from 1913-1917.
As with just about every Blue Mountains lookout, you get some spectacular vistas at both sunrise and sunset.
The “official” Walls Lookout and the end of the walking trail is a small rock outcrop, which provides a great view to the west over the Grose Valley. Blackheath Walls is on the opposite side of the valley, with Hanging Rock and Baltzer lookouts near the middle of the photo below, and Burra Korain Head to its right.
There are some informal trails that take you down to a few small pagoda-like rock formations near the (unfenced) cliff edge. Looking east down the Grose Valley is Mount Banks in the distance.
Getting to Walls Lookout
The easiest and shortest way to reach Walls Lookout is from the Pierces Pass carpark, which is at the end of Pierces Pass Road (off Bell Line of Road). It’s an unsealed road, but suitable for all vehicles.
The signposted track starts on the southern side of the carpark, passing behind the toilet block as it climbs gently up the the side of a gully.
After a few hundred metres you, get the first views of the distant cliffs, and after 0.5km you meet another access track that descends from the top of Pierces Pass Road.
The alternate route to the lookout starts from the very top of Pierces Pass Road, just after you turn off Bells Line of Road. This way is about 2.6km return, compared to about 1.5km from the end of Pierces Pass Road.
