Lucas Cave is the most interesting cave at Jenolan. It is recommended to visit this cave if you do not have time or do not want to visit more than one cave. It offers the biggest chamber of all Jenolan caves and a wider range of different speleothems. All in all a worthwhile visit of 90 minutes.
The Cathedral is the highest chamber of this tour, and also the highest chamber of all Jenolan caves. It is used for weddings and for concerts for example by Dame Joan Sutherland or the Vienna Boys Choir. There are now and then concerts in this hall. The dates are published on the official website of Jenolan.
The most impressive speleothem is just a common pillar or column, where stalactite and stalagmite have grown until they joined and formed a column from the ceiling to the floor. But this one is special as it is broken into two parts, with a rather wide gap in between, Thats why it is called Broken Column. The reason is porbably a movement in the debris it is grown on.
The Jenolan cave system has a lowest level with a cave river. Here at Lucas is the only possibility to get a glimpse of this underground river.
Lucas cave was named after John Lucas. He was a local parliamentarian and was responsible for having a reserve declared for the protection of the caves.
