Crater Falls is really a waterfall lovers excuse to do the two-hour return track to Crater Lake. The waterfall itself is funneled into a narrow chute before plunging less than 5m and then cascading further downstream as it leaves the pocket of forest and enters the open swampy tussock grasslands where it joins Ronny Creek. If you're just hiking to the waterfall, it's a one-hour return hike from the Ronny Creek Trailhead, which is the car park before the last one at Dove Lake.
