Tarra Falls is really nothing more than an elongated flat cascade that gently tumbles along an incline deep in the Tarra Bulga National Park. I could make an argument that this waterfall borders on being a water slide if it weren't for the forbidden access away from the wooden platform. It's only minutes away from Tarra Valley (site of the car park for Cyathea Falls) and signposted so it's pretty easy to find. The walk to its viewing deck is also very short.
