Getting to Newnes
You will need your own vehicle to get to Newnes, as there is no public transport, other than by taxi from Lithgow (50km away). (Lithgow can be reached by train from Sydney.) There are several ways to find your way to Newnes:
Using Google Maps
If you have a mobile phone with Google Maps, just set your phone to give you directions to 3406 Wolgan Rd, Newnes NSW 2790 and away you go.
From Sydney: Head west across the Blue Mountains, either via Katoomba, or via Windsor and Bell; from the Lithgow traffic lights on the Great Western Hwy proceed towards Bathurst for 6 km and then take the road towards Mudgee. (Castlereagh Highway). 4km down you will find Wallerawang Power Station on your left and a United service station on your right. That's the turn-off to Newnes is at Lidsdale.
From Bathurst: Follow the Great Western Highway to the Mudgee Road, then as above. It is also possible to follow side-roads through Wallerawang.
From Mudgee: Watch for the sign-posted turn-off (sharp left) at Lidsdale.
The drive from Lidsdale to Newnes is 35km following Wolgan Road and normally this takes 40 minutes. 5km from Lidsdale is Wolgan Gap, a steep windy stretch of road desending into the Wolgan Valley. The last 9km of Wolgan Road is gravel road through National Park. At Newnes is a location sign and you can't miss the historic Newnes Hotel.
Drivers towing a caravan will have to be sure they have the vehicle strong enough to pull the caravan back out of the Wolgan Valley again.
Small trailers should present no difficulty.
