By car
Blackheath is on the Great Western Highway, after Medlow Bath and is quite hard to miss. It takes approximately 1.5 to 2 hours from Sydney, depending on which road you take, and the traffic conditions.
By train
Cityrail trains stop at Blackheath Station every two hours off-peak and weekends, and more frequently at peak times. An adult return ticket from Sydney's Central Station to Blackheath is $19 for an off-peak return, or $27 if leaving before 9AM.
The station is located near the main shops and gives good access to the town centre. A shuttle operates over the road from the station. Govett's leap is around 3km from the station, and Evan's lookout is further. So, best to have a plan worked out if you are hoping to tour the attractions an vistas that the area is famous for.
