Byaduk - Byaduk Caves
Byaduk Caves are part of a lava flow from Mount Napier which solidified and the caves were formed by molten lava continuing to flow beneath.
The caves contain wrinkles, stalactites and stalagmites, columns and ropy lava. They are the most extensive and accessible set of lava caves in Victoria. Only one cave, Harmans 1, is open to the public. Wear appropriate footwear and clothing and take a torch.
Bentwing bats spend winter in some of the caves. To avoid winter food shortages the bats slow their body systems down in what is known as torpor where their body temperature matches that of their surroundings. Disturbance during this period can kill them. Do not shine lights on bats, avoid loud noises and retreat from the cave if bats are seen.
The largest caves are 18 metres wide, 10 metres high and extend 20 metres below the surface. There are walking tracks which follow the cave edges and have a number of viewing points to observe the flora, fauna and lava features.
Byaduk Caves are reached via the Byaduk Caves Road, 18 km from Hamilton on the Hamilton-Port Fairy Road (just north of the town of North Byaduk).
In the area are Tumuli (Lava Blisters).
