Moondyne Cave was discovered in 1881 by Joseph Bolitho Johns (1826 to 13-AUG-1900). It was named after him, he was Western Australia's best known bushranger better known as Moondyne Joe.

A complete cave restoration program saw Moondyne Cave reopened for cave awareness tours with restricted group numbers in 1992. Visitors are supplied with basic caving equipment including electric lights (miners light), helmet, overalls and souvenir gloves.

The cave has two large chambers, the lower chamber reaches the water table. It is called Snowflake Chamber and contains an crystal pool, which is completely covered with calcite flakes. This chamber has some side extensions with fine displays of helictites, which are visited on cave trekking tours. The carbon dioxide levels are often high in this chamber.

The upper chamber contains many large columns and stalagmites. There are also some very long straws.
