Rochester Falls is the area's marquee natural sight: a wide, low cascade tumbling over a wall of hexagonal basalt columns, framed by sugarcane fields and the rising green slopes inland. The columns are an unusual geological feature and the most photographed aspect of the falls; the drop is modest (about ten metres), but the rock structure makes the picture.
Local boys regularly leap from the top into the deep pool below, and bathing in the lower pool is possible when the river is calm. The road in turns off the main coast road just east of Souillac and runs through cane fields for several kilometres on a rough but driveable track.
