Yerraldarie is an abandoned mining town in the west of the NSW Blue Mountains National Park. Reached either via Goulburn or Oberon in the NSw west of the Blue Mountains there are two towns side by side. Prior to the building of the Warragamba dam access was along the Burragorang Valley. The lake that the dam created now cuts this area off. The towns are now managed by the NSW Parks Service. There is good camping available and the facilities work well. It is isolated and while access is by a two wheel drive road there are opportunities for four wheel driving. The natural environment maintains much of the areas natural beauty and marsupials, birds and reptiles are common if not abundant. The site is a good example of small scale mining and European heritage. Aboriginal heritage need further study here and would be a valuable area of study for those interested.
