Don't make the mistake of letting the entrance scare you off. It's worth it :)

On the way through the cave to the waterfall, you'll need a flashlight—your cell phone's if necessary, but a proper flashlight is better. The cave curves around several times. There's a high risk of twisting your ankle on the scree in the dark.
