Cradle Mountain - Lake St Clair National Park, Tasmania
More of a rocky cascade then significant waterfall, Boulder Falls cascades around a large rock in the middle of the Mersey River into a pool below, with another huge boulder just upstream attesting to how the falls got their name.
The falls are situated a few hundred metres downstream of the popular D'Alton Falls, however the track terminates there so making it downstream is difficult and potentially dangerous, as you have to skirt along the edge of a deep gorge, travelling downstream until the falls come into view. Even the view shown on this page required some dicey scrambling to attain, to get about halfway down the gorge to a section of flat ground where the falls are at least partially visible, but getting closer for a good view would be impossible without an abseil, or by rafting down the river from further upstream.
If you make it to Boulder Falls, be sure to continue a little ways further downstream to Cathedral Falls, a much larger and more impressive waterfall, although it too is hard to satisfactorily view.
