Byaduk Caves

Byaduk Caves, nestled within Mount Napier State Park, showcase Australia's most extensive lava caves. Formed approximately 30,000 years ago, these caves consist of interconnected underground tubes created when lava from Mount Napier solidified on the surface while molten lava continued to flow beneath. The largest cave measures 18 meters wide, 10 meters high, and extends 20 meters below the surface. Accessible by 2WD vehicles with ample parking, visitors can enjoy a short walk along trails interconnecting the caves, offering surface-level viewing areas.
