The Blue Mountains is famous for dramatic cliff-top views, but beneath the surface lies Jenolan Caves, one of Australia’s most spectacular underground cave systems. Located west of Katoomba in the Jenolan Karst Conservation Reserve, these ancient limestone caves offer a completely different Blue Mountains experience.
Exploring Caves in the Blue Mountains
Jenolan Caves is the main cave destination in the Blue Mountains, sitting within the Greater Blue Mountains UNESCO World Heritage area. What makes these caves extraordinary is their age: at 340 million years old, they’re the world’s oldest discovered open caves.
Underground rivers have carved intricate passages through limestone, creating chambers decorated with stalactites, stalagmites, columns and crystal formations. The cave system features 11 show caves plus adventure options, each revealing formations that have been developing in darkness for millions of years.

What Makes Jenolan Caves Special
Jenolan Caves isn’t just one cave but an extensive system offering multiple touring options. Here’s what sets it apart:
- 340 million years old: Among the oldest caves on Earth, predating dinosaurs
- 11 show caves: Each with unique features, from massive chambers to delicate crystal formations
- Adventure caving options: For those wanting to go beyond standard tours
- Underground rivers: Active waterways still shaping the caves today
- Crystal-clear pools: Reflecting pools that mirror the formations above
The variety of caves means you can choose experiences based on your interests and physical abilities. Some caves feature easy walking paths suitable for families, while others involve steeper stairs and tighter passages for more adventurous visitors.
Popular Cave Tours at Jenolan
Each show cave has distinct characteristics and requires a guided tour. Here’s what the main caves offer:
- Lucas Cave: The crowd favourite, featuring the massive Cathedral chamber that could fit a cathedral inside. This is the only wheelchair-accessible cave and works well for first-time visitors. Tours run approximately 90 minutes.
- Temple of Baal: Considered the most decorated cave in the system, with an incredible concentration of formations. The tour involves more stairs than Lucas Cave but rewards you with some of Jenolan’s finest decorative features. Allow 90 minutes.
- Orient Cave: Known for delicate, intricate formations including fine straw stalactites and intricate crystal work. The tour is moderately challenging with stairs and uneven surfaces. Duration is around 90 minutes.
- Chifley Cave: A shorter, easier tour perfect for families with young children or those with limited time. Features beautiful formations without extensive walking or stairs. Tours run about 60 minutes.
- River Cave: The most adventurous standard tour, following the underground river through passages and chambers. Involves stairs, low sections and a more immersive cave experience. Expect 2 hours for this tour.
All tours are guided-only for important reasons. Guides protect the fragile formations from damage, ensure visitor safety in the underground environment, and share the fascinating geology and history that make each cave special.

Plughole Cave Adventure Tour: This challenging experience involves crawling through tight passages, squeezing through narrow gaps, and getting muddy. It’s caving as explorers experienced it, complete with helmets and headlamps. You’ll see areas not accessible on show cave tours.
Mammoth Cave Adventure Tour: Another adventurous option featuring more technical caving, including ladder climbs and challenging passages. Both adventure tours require reasonable fitness and flexibility.
Requirements and booking:
- Minimum age restrictions apply (typically 16+ for adventure tours)

- Tours often book out weeks ahead, especially school holidays
Planning Your Visit to Blue Mountain Caves
Getting to Jenolan Caves
Jenolan Caves sit approximately 175km west of Sydney, making it roughly a 3-hour drive. The location is west of Katoomba, near the town of Oberon.
Journey details:
- From Sydney: Via M4 and Bells Line of Road, or via Great Western Highway
- From Katoomba: 90 minutes south-west (80km)
- From Oberon: 40 minutes east (35km)
The final approach to Jenolan involves winding mountain roads with steep sections and tight corners. Winter can bring ice and snow to these roads, so check conditions before travelling. No public transport services to Jenolan Caves, making a car essential for visiting.
Entry and Tour Bookings
Access to the Jenolan Karst Conservation Reserve itself is free. You can walk the surface trails and enjoy the reserve without purchasing cave tours. However, entering any show cave requires a paid tour ticket.
Booking information:
- Tour prices vary by cave (check website for current prices)
- Online booking strongly recommended, especially weekends and holidays
- Tours run throughout the day from morning to afternoon
- Book multiple tours to make the most of your visit
- Between tours, explore the reserve’s walking tracks
What to Bring and Wear
Caves present a unique environment that requires specific preparation:
- Footwear: Sturdy shoes with good grip (cave floors can be wet and slippery)
- Clothing: Warm layers (caves stay 15-17°C year-round, regardless of outside temperature)
- Camera: Photography allowed, but no flash (protects delicate formations and cave wildlife)
- Water and snacks: Facilities available on the surface, but bring supplies for between tours
Different tours have varying physical requirements. Lucas Cave suits most fitness levels, while River Cave and adventure tours demand more mobility and stamina.
Where to Stay Near the Caves
Jenolan Caves House
The historic Caves House sits at the cave entrance, offering the most convenient accommodation. This heritage building has been hosting visitors since the 1880s, featuring rooms with period character and a restaurant serving hearty meals. Staying on-site means you can take multiple cave tours across two days without driving, and enjoy the reserve at sunrise or sunset when day-trippers have left. Book well ahead, particularly for weekends and school holidays.
Nearby Accommodation Options
If Caves House is booked out or doesn’t suit your budget, consider these alternatives:
- Oberon: 30-40 minutes from Jenolan, offering motels, pubs and holiday parks
- Lithgow: A larger town with more accommodation choices, about 1 hour from the caves
- Katoomba/Blue Mountains: Combine cave visit with broader Blue Mountains stay (90 minutes away)
- Day trip: Manageable from Sydney or the Blue Mountains, though it’s a long day
Other Attractions at Jenolan Karst Conservation Reserve
The caves are the headline act, but the reserve offers more to explore between tours:
- Blue Lake: Short walking track to a stunning aqua-blue lake fed by underground springs
- Carlotta Arch: Natural limestone arch forming the Grand Arch entrance to the caves area
- McKeowns Valley: Longer walking trails through pristine bushland
- Historic cemetery: Final resting place of early cave guides and workers
- Wildlife watching: Wombats commonly graze near Caves House at dusk, plus wallabies and lyrebirds
These surface attractions provide excellent ways to fill time between cave tours or extend your visit beyond the underground experience.
Best Time to Visit Blue Mountain Caves
The caves themselves are a year-round attraction thanks to their constant temperature. Whether it’s 35°C outside in summer or freezing in winter, the caves maintain a steady 15-17°C, making them comfortable any time of year.
Seasonal considerations:
- Spring/Autumn: Best weather for surface walks and drives, moderate visitor numbers
- Summer: Caves offer cool relief from the heat, but weekends get very busy
- Winter: Fewer crowds on weekdays, but roads can be icy (chains may be required)
- Weekdays vs weekends: Weekdays are significantly quieter for all tours
Plan to spend a full day at Jenolan if you want to take multiple cave tours and explore the reserve. Most visitors do 2-3 cave tours in a day, with walks and breaks between.
Combining Your Cave Visit with Blue Mountains Attractions
Jenolan Caves works well as part of a broader Blue Mountains itinerary:
Multi-day options:
- Hampton/Lithgow route: Explore historic mining towns and attractions between Lithgow and Jenolan
- Oberon loop: Return via Oberon and Mount Victoria for different scenery
- Classic Blue Mountains: Combine caves with Katoomba’s Three Sisters, Echo Point and scenic walks
- Bells Line of Road: Take the scenic northern route through Mount Tomah and Mount Wilson
Most visitors either dedicate a full day specifically to Jenolan or build it into a 2-3 day Blue Mountains trip. The caves offer a dramatic contrast to the region’s famous lookouts and bushwalks, giving you an entirely different perspective on the ancient landscape that makes the Blue Mountains so special.
