Ancient Caverns Beneath the Blue Mountains

Jenolan Caves lie in the Blue Mountains region of New South Wales. Clays found in the caves have been dated to about 340 million years old, making them among the oldest known open caves in the world. The Gundungurra people called the area Binoomea, meaning dark places.

The caves formed as slightly acidic water dissolved limestone, creating chambers decorated with stalactites, stalagmites and shawls. Lucas Cave has a vast Cathedral chamber where concerts are held, and the Orient Cave sparkles with delicate white and orange formations.

Visitors drive through the Grand Arch, a huge natural archway. In the 1880s, Jenolan became among the first caves in the world to use electric lighting, and Caves House has welcomed guests since the 1890s. Outside, platypus sometimes swim in the Blue Lake, colored by minerals in the water.
