This short walk leads to the Natural Bridge, an ancient lava flow where the roof has collapsed which you can enter and explore. At the end of the walk, you will come to a section where the roof of the lava flow remains intact, forming a cavern that you can explore. There's a good chance you'll spot koalas and kangaroos on the walk if you keep your eyes peeled. Carry a torch and wear appropriate shoes as the cavern is dark and slippery. This walk can also be commenced after driving along the Natural Bridge Road to the Natural Bridge carpark. A 200m walk from the carpark leads to the Natural Bridge cavern.
All walks start from the picnic area or the Lake Surprise Lookout carpark. Ensure you have good shoes for the uneven terrain. A hat, water and sunscreen are essential. You may encounter wildlife including snakes on these walks, as this is where they live. They are protected here. If you see a snake on the track leave it alone and wait for it to leave.
