Jenolan Caves

Jenolan Caves sit in the Jenolan Karst Conservation Reserve on the western edge of the Greater Blue Mountains World Heritage Area in NSW. They are roughly a three-hour drive west of Sydney, about 75 km south-west of Katoomba, and the closest town is Oberon.

Yes. CSIRO and university researchers have dated clays inside the caves to around 340 million years, which makes Jenolan the oldest known open cave system on Earth. The surrounding Silurian limestone is older again, formed from a marine reef about 430 million years ago.

There are 11 show caves developed for guided visits at Jenolan, including Lucas, Chifley, Imperial, Diamond, River, Pool of Cerberus, Temple of Baal, Orient, Ribbon, Jubilee and Nettle. Tour rosters typically rotate a smaller selection of these through any given week.

No. Every cave at Jenolan can only be entered with a licensed guide on a booked tour, both to protect the formations and for visitor safety. There are no self-guided routes inside the caves themselves, though the surrounding bushwalks, Carlotta Arch and the Grand Arch are free to explore.

Lucas Cave is the classic first tour. It is the largest of the show caves, takes about 1.5 hours, and showcases the Cathedral Chamber and the Broken Column, giving a strong sense of why Jenolan is so famous.

Imperial Cave is the easiest of the show caves, with the fewest steps and the most level walkways, making it the standard recommendation for visitors with reduced mobility, young children or grandparents. Ribbon Cave is short and gentle but involves stairs, so Imperial is usually the more accessible choice.

Jenolan offers off-track adventure tours through River Cave, Mammoth Cave and the Plughole (Aladdin) section, with crawling, climbing and abseiling involved depending on the trip. These are guided experiences for fitter visitors and require advance booking.

The historic Jenolan Caves Road through the Five Mile section was severely damaged in 2022 floods and remains closed to general traffic. Visitors approach instead via Hampton on the Great Western Highway or via Oberon, both of which join Jenolan Caves Road from the western side.

Jenolan Caves House, the heritage Federation-era hotel opened in 1898, is the on-site accommodation, with rooms in the Grand Classic, Mountain Lodge and Gatehouse wings. Nearby alternatives include Binda Bush Cabins and accommodation in Oberon, Hartley and the upper Blue Mountains towns.

The caves stay at a steady temperature of around 15 degrees year-round, so weather inside is never a factor. Spring and autumn are the most pleasant for the surrounding bushwalks; winter brings frosty mornings and occasional snow on the road, while summer weekends and school holidays are the busiest.

Jenolan lies on the traditional Country of the Burra Burra clan of the Gundungurra Nation, who have known the caves for thousands of generations. The Gundungurra name for the caves is Binoomea, meaning "dark places", and the Dreaming story of Gurangatch and Mirragan describes how the cave system was carved.

Yes, advance booking is essential. Tours run on fixed schedules with limited group sizes, popular sessions sell out on weekends and during school holidays, and booking ahead is the only reliable way to secure the cave and time you want. Note that Jenolan is currently closed for flood-recovery works and is expected to reopen in late 2026, so check jenolancaves.org.au for the latest tour availability before planning your trip.
