- The 3.8km (one way) walk is on a raised plank walk through the lush forest and alongside rushing rivers, takes about 45 minutes until the bats observatory area and another 2km to the entrance of the World’s largest cave passage. Tours to these caves are led by World Heritage Park Guides and leave the office at 2.00pm and 2.30pm (3 hours tour) daily.
- Pause in Deer Cave’s ancient riverbed and wonder at the force of the water that once roared through, tumbling huge boulders around and carving the scalloped walls. Above your head columns of water stream from the roof to join the river passages that twist and turn through the mountain, continuously enlarging and changing the shape of the cave.
- The squeaking noise you’ll hear in the cave is the 3 million strong colony of Wrinkle Lipped bats stirring themselves as they sense that dusk is not far away and they begin to prepare to leave the cave to feed on flying insects. The birds you see swooping through the darkness are the swiftlets returning to roost in the cave. The path continues to wind deeper into the blackness of the cave and suddenly the Garden of Eden appears in the distance, a green oasis shining in the sunlight. Nearby are Adam and Eve’s Showers spouting 30 metre columns of water to the river far below.
- Deer Cave is awesome, large and bold but only 100 metres away is Langs Cave. Small and intimate, with walls beautifully decorated with long shawls, layers of rim stone pools on the floor, and throughout the cave, spectacular stalagmites and stalactites.
- In this smaller cave the bats are easier to see, small white cave prawns hide in pools of water and shimmering near the roof are strands of web spun by the thread worm larvae waiting for a passing meal.
- This tour is timed to coincide with the bat exodus.
- Drinks and snacks are on sale each afternoon.
