Jenolan Caves are caves in the Blue Mountains, New South Wales, Australia; 175 kilometres west of Sydney. They are the most visited of several similar groups in the limestone of the country, and the oldest discovered open caves in the world. They include numerous Silurian marine fossils and the calcite formations, sometimes pure white, are noted for their beauty. The cave network is very large, with over 40 km of multi-level passages, and the complex is still undergoing active exploration. The caves are a popular tourist destination, with several kilometres of the caves rendered accessible to paying visitors and well lit.
By measuring the ratio of radioactive potassium and trapped argon gas, which was produced when the potassium decayed, scientists determined the age of the clay in the caves to be approximately 340 million years old, thereby making the cave complex the world's oldest known and dated open cave system. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) in association with the University of Sydney and the Australian Museum lead the efforts in scientific research into the caves.
For thousands of years, the Jenolan area has been part of the culture of local indigenous peoples. The area holds significance to the Gundungurra people, who knew it as 'Binomil' or 'Bin-oo-mur'. A Dreamtime creation story of the Gundungurra people describes how the countryside came into being, and involves a struggle between two ancestral creator spirits - one a giant eel-like creature, Gurangatch, and the other, Mirrigan, a large native cat or quoll. In the early years of the 20th century, the Gundungurra people penetrated the caves as far as the subterranean water, carrying sick people to be bathed in this water, which they believed to have curative powers.
In approximately 1835-40 the area was recorded for the first time by either James, Charles or Alf Whalan, three brothers who each claimed to have discovered the caves while searching for a bushranger, James McKeown, whom they claimed used the caves as a hide-out. One of the less-visited caverns in the area is called McKeown's Hole, however there is no actual evidence of his existence. It is more likely the brothers were searching for cattle that had strayed from their nearby farm.
The caves, then known as the Fish River Caves, came under New South Wales Government control in 1866, becoming only the second area in the world reserved for the purpose of conservation and the following year Jeremiah Wilson was appointed as the first "Keeper of the Caves". Wilson not only explored the already known Elder and Lucas Caves but later discovered the Imperial, Left Imperial (now known as Chifley), Jersey and Jubilee Caves.
The caves were open to tourism early, but there was little protection from visitors damaging formations until souveniring was banned in 1872. In 1884 the name Jenolan Caves was adopted. The name "Jenolan" comes from the Gundungurra word, "Genowlan", the for a "high place shaped like a foot".
The road to the caves originally went in from Tarana, which meant that travellers from the south had to take a long, roundabout route of about 90 miles from Katoomba to Oberon, and, from there, to Tarana. In the mid-1880s, hotel keepers in Katoomba wanted to improve business by constructing a road to the Caves from their town, but the steep, rough ground between the caves and town was a major obstacle, and several attempts failed. However, representations were made to the state premier by Peter Fitzpatrick of Burragorang, who was connected to some mining operations near Katoomba.
In April, 1884, William Marshall Cooper, Surveyor of Public Parks for the State Government, was assigned the job, and worked out a horse-and-carriage track in a 10-day trek from Katoomba to the Caves. The route was, he remarked, 26.5 miles from the Western Hotel in Katoomba. "... Anyone accustomed to walking can do it comfortably in 12 hours... when the proposed horse track is completed, it will be a very enjoyable ride of five hours." It became known as the Six Foot Track.
By 1885, Parliament had approved ₤2,500 for the construction of Cooper's bridle track, with the work starting at the most difficult area, the Megalong Cleft, where a zig-zag had to be cut, partly in solid rock, to reduce the grade to 1:5.5. The first recorded passage of the completed bridle track from Katoomba to Jenolan was by the governor, Lord Carrington, in September 1887. Lord Carrington also made the first official visit to the caves at the completion of his journey, accompanied by Wilson.
In 1898 the current Caves House guesthouse was built, replacing the earlier wooden accommodation house built by Jeremiah Wilson, which had been destroyed in a fire.
James Wiburd become "Keeper of the Caves" in 1903 and discovered five more caves within eighteen months: the River, Pool of Cerberus, Temple of Baal, Orient and Ribbon Caves. He remained Keeper until 1932, when he left following a dispute over the development of the Ribbon Cave for tourism.
The Chifley Cave, originally known as the Left Imperial Cave but named for Prime Minister Ben Chifley in 1952, was the first of the caves to be lit with electric light, as early as 1880. In 1968, the Orient Cave became the first in the world to be cleaned, due to contamination from a nearby coal boiler. This was entering the cave via a new tunnel blasted 400 feet through to the Orient cave in the 1950s to allow easier access (entering at Bat End). Steam cleaning was found to be damaging to the crystal formations, due to the rapid expansion and contraction caused by the heat from the steam, and these days water from the caves' own underground rivers is used if cave cleaning becomes necessary.
Since 2011, CSIRO (in association with Australian Nuclear Science and Technology Organisation) has been using a new hand-held mapping system to map some of the caves in three-dimensional detail.

Located 3 hours drive for day visitors from Sydney and Canberra, Jenolan Caves attracts over 250,000 visitors a year, making it one of the most popular tourist locations in rural New South Wales.
There is no public transport to Jenolan Caves. However, there are large carparks and a range of coach operators bring tourists from Sydney and Katoomba every day.
Ten of the area's "dark caves" are open for regular guided tours every day (1 to 2 hours per tour). These 'show' cave tour sizes vary. For example, the delicate Pool of Cerberus Cave can have only 8 on a tour, while the Lucas Cave (with its large chambers) can have up to 65 people per tour.
Tours also vary in difficulty, for example the Imperial Cave has the fewest stairs, while the River Cave is the most strenuous. However, the average tourist can tour any of these 'show' caves.
A self-guided tour of the huge Nettle Cave/Devils Coach House is also available. The self guided tour gives visitors a choice of many languages. One of the choices on the self guided tour is an Aboriginal culture commentary.
Night tours run every night except Sundays, including the popular ghost tour, 'Legends, Mysteries & Ghosts'.
Several undeveloped caves are available for Adventure Caving (2 hours to all-day tours). These Adventure Caving tours include the Plughole Tour, which runs daily and includes basic abseiling. Other more challenging Adventure Caving tours are available.
The Cathedral Chamber, part of the "Lucas Cave" is famous for its acoustics. At least twice every month, underground concerts take place in this chamber. Several times a year, concerts also take place in the Grand Arch, including the annual 'Carols in the Caves', which raises money for charity.
During NSW School Holidays, specially developed tours are available for children. Jenolan Caves has long been a popular destination for school excursions.
When visiting Jenolan Caves, tourists can stay at the heritage-listed Jenolan Caves House, designed in 1897 by government architect, Walter Liberty Vernon, as a resort or retreat for the wealthy. To cater for the expectations of the well-to-do, Vernon included a ballroom and grand dining room (now Chisolm's Restaurant).
Chisolm's is open for dinner every day, serving modern Australian cuisine. Facilities include an hotel/motel complex, self-contained cottages, restaurant, bar and cafe.
The huge Jenolan Reserve is a National Park, located in the World Heritage Blue Mountains Area, where several signposted bush trails enable tourists to glimpse Australian birds and native wildlife, including kangaroos and platypus.
Large portions of this extensive cave system are accessible only to cavers, especially those areas along the underground river system; but, there are ten caves at Jenolan that have been developed for regular tourism.
- Lucas Cave: Discovered in 1860 and the most popular among visitors. The Lucas Cave (named after local politician John Lucas who pushed to have the caves preserved in the 1860s) features a number of large chambers including the Cathedral, over 50 metres high, and the vast Exhibition Chamber which contains the Broken Column formation. Due to its size and acoustics, the Cathedral Chamber is also used for wedding ceremonies and recitals.
- River Cave: Discovered in 1903, the River Cave is the most extensive show cave at Jenolan and includes some of its most famous features, including the Minaret, the Grand Column and the Queen's Canopy, as well as part of the River Styx. Until 1923 when a concrete bridge was built, a section of river in this cave was crossed by a small boat.
- Chifley Cave: Discovered in 1880, the Chifley Cave was known as the Left Imperial Cave until 1952, when it was renamed in honour of the then recently-deceased former Prime Minister Ben Chifley, who grew up in nearby Bathurst. The Chifley Cave was the first cave in the world to be lit by electric light, in 1880. Two of the cave's chambers are still decorated with historic coloured lights.
- Imperial Cave: Discovered in 1879, this is the easiest cave to visit for tourists. The Imperial contains some of the best fossil deposits and several Tasmanian Devil bones. Note that whilst fossils may not be clearly evident to the casual visitor, in fact the bedrock in which the caves are formed is richly endowed with marine fossils.
- Orient Cave: Discovered in 1903, the Orient Cave was not opened to public inspection until 1917, to allow for the installation of electric lighting and paths. This cave contains some of the grandest formations in the complex and was steam cleaned to preserve them in 1968. Until 1954, this cave, along with the Temple of Baal and Ribbon Caves, were only accessible through the River Cave. That year, the Binoomea Cut was constructed near Caves House to facilitate easier access to these caves. An LED-based lighting system was installed in this cave in 2009.
- Ribbon Cave: Discovered at the same time as the Orient Cave, it was originally part of that tour but is now visited separately. The Ribbon Cave is only 60 metres long but is richly decorated. This cave is known for particularly good examples of 'ribbon' helictites.
- Pool of Cerberus Cave: Discovered in 1903, this cave is a lower arm of the River Cave. The major formations here are the Bath of Venus and part of the underground river system that forms the Pool of Cerberus itself. It also includes rare aragonite formations.
- Jubilee Cave: Discovered in 1893, the Jubilee Cave is the longest show cave at Jenolan. It takes the longest amount of time to visit as it is fairly remote from the other caves. Of the caves shown at Jenolan to the public it is the least visited due to the length of the tour and the small tour groups that can be taken there.
- Temple of Baal Cave: Discovered in 1904, the Temple of Baal Cave consists of only two large chambers, one of which is dominated by the huge 9-metre shawl formation called the Angel's Wing. The cave is also noted for a high incidence of the peculiar formations known as Helictites. The name derives from the biblical story of Baal, and the feature names in the cave largely relate to that story. Recent[when?] development work has upgraded the lighting and added an audio accompaniment to the cave experience.
- Nettle Cave: The Nettle Cave lies between the Grand Arch and the Devils Coach House. The cave takes its name from the nettles which grow near its entrance (note that raised walkways protect visitors from their stings); an upper part of this cave can be seen from inside the Devil's Coach House. Originally shown as a guided tour, the cave was closed to the public in 1932. In December 2006, this cave was re-opened to the public as a self-guided audio tour, combined with the adjoining Devil's Coach House. The Nettle Cave hosts "Crayfish backs", stromatolites shaped by cyanobacteria, light and wind. They are estimated to be at least 20,000 years old.
- Arch: The road from Sydney passes through the Arch and six of the cave tours leave from assembly points within it. Adjacent to the Grand Arch is the Devil's Coach House, a vast open-ended chamber that forms part of the many nature walks in the area. High above both of these is Carlotta Arch, a free-standing arch that is all that remains of a higher cavern system long since eroded and collapsed. Along with these areas, there are several other caves in the area, some of which are available for special tours.
- Elder Cave: Named from the Elder tree, visitors would climb down to enter the doline (sinkhole). Discovered in 1848, 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.
- Aladdin Cave: The Aladdin Cave was first explored in the hope of developing a shorter path to the Jubilee Cave. It has similar decorations to the Jubilee Cave.
- Jersey Cave: An extension of the Elder Cave. One of the features is a fossilised thylacine skeleton.
- Arch Cave: This cave lies above Nettle Cave and part of it can be seen from the Devils Coach House. The entrance to this cave is at the base of Carlotta Arch (hence the name) and the stairs and locked gate can still be reached although the Arch Cave.
