The Horizontal Falls have been described by naturalist David Attenborough as "one of the greatest wonders of the natural world". They are formed from a break in-between the McLarty Ranges, reaching up to 25m in width. The natural phenomenon is created as seawater builds up faster on one side of the gaps than the other, creating a waterfall up to 5m high on a spring tide. Within each change of the tide, the direction of the falls reverses, creating vast tidal whirlpools.
The northern, most seaward gorge is (Poulton Creek.) 20 m (66 ft)-wide and the southern, more inland gorge ( ) is 12 m (39 ft). Above each of the gorges are natural reservoirs between 6–8 km (3.7–5.0 mi)-long, which fill and empty with seawater through the gorge openings. The inner gorge is also partly fed by fresh water from
