Description

Lucas Cave is the most interesting cave at Jenolan. It is recommended to visit this cave if you do not have more 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 tour starts with a 252-step stair climb, from the road through Grand Arch up to the cave entrance. In other words, half of the steps are actually outside the show cave. Nevertheless, this is a rather strenuous tour with many steps, but its definitely worth the effort.

The Cathedral is the highest chamber of this tour, and also the highest chamber of all Jenolan caves, 54 m high. It is sometimes used for weddings and for concerts, for example, by the Australian-born coloratura soprano Dame Joan Sutherland or the Wiener Sängerknaben (Vienna Boys Choir). The dates of the infrequent concerts are published on the official website of Jenolan. It was used for such purposes from the very beginning, so it has actually 160 years of history. Its acoustics is famous.

In the next chamber, the Exhibition Chamber, the most famous speleothem of the cave is located. It 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, that's why it is called Broken Column. The reason for the crack is most likely a movement in the debris it has grown on.

Lucas Cave was named after John Lucas. He was a local parliamentarian and was responsible for having a reserve declared in 1866 for the protection of the caves. The cave was named the Lucas Cave in recognition of his contribution.

The Jenolan cave system has a lowest level with a cave river, this section is called Underground River or ShowcaveRiver Cave. Here at Lucas was the only possibility to get a glimpse of this underground river. The blue-green water flows 20 m below the tour path, the gorge is crossed on a bridge. In the early days it was possible to make an underground boat ride. It seems this part of the cave is also connected to Imperial Cave, and it is now part of that tour.
