Are there any safe caves for tourists to explore in the Knuckles Range?

The Nitro Cave is the most famous one in the Knuckles range. It is a large cavern home to thousands of bats. The trek there is quite steep and requires a good level of fitness. You do not need professional climbing gear but a powerful headlamp and shoes with excellent grip are mandatory because the floor is covered in guano and very slippery. Always go with a local guide who knows the weather patterns as these areas are prone to flash mists.
