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.

Located 3 hours drive 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. Since 2008, Jenolan Caves has won many tourism awards, including 4 gold awards in the Qantas Australian Tourism Awards (2011 and 2013). 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.
