The Elder Cave
Named from the Elder tree, visitors would climb down to enter the doline (sinkhole).
The Elder Cave was the first of the caves at Jenolan to be found and opened to tourists.
It was later considered too difficult to develop adequately and tours eventually ceased; however in the late 1990s the Elder Cave was re-opened for adventure caving, and is sold as the Plughole Tour.
It is not as decorated as the regular show caves, but features signatures left
by early visitors and includes a short section of the Imperial Cave.
