Mount Napier State Park

Mount Napier State Park is a state park in Victoria featuring volcanic landscapes and a 212-meter-high mountain surrounded by manna gum forest. The property spans about 2800 hectares and includes extensive underground caves formed by ancient lava flows.

The mountain formed roughly 10,000 years ago when a volcano erupted, creating the geological structures and caves visible today. The area gained official protection in 1987 as a state park.

The Indigenous Australians named the mountain Tapoc, maintaining strong connections to this land through ceremonies and traditional practices over generations.

The Byaduk Caves require torches and sturdy footwear to explore the underground tunnels safely. Visitors should prepare for uneven ground and dim lighting when venturing through the cave system.

The Byaduk Caves formed through a distinctive process where the lava surface cooled and hardened while molten material continued flowing beneath, leaving behind an extensive tunnel network. This geological process created the branching cave system visitors explore today.
