The Wombeyan Caves are limestone caves set in the Wombeyan Karst Conservation Reserve, New South Wales, Australia. It is located within the Southern Highlands about 50 km north of Goulburn. Access is by the Wombeyan Caves Road from either Mittagong in the east or from the Goulburn-Oberon Road in the west. The caves reserve is located towards the western end of the Wombeyan Caves Road. The part of the Wombeyan Caves Road east of the reserve is very rough and has many curves and narrow stretchs as it descends down to Wollondilly River and then up very rugged mountains.
