Australia's 'Most Unusual Natural Wonder' Is a Horizontal Waterfall You Can Ride Through
One of the world’s greatest natural wonders, the ocean phenomenon creates horizontal currents that look like waterfalls turned sideways. Sir David Attenborough described it as “Australia’s most unusual natural wonder.”
The Horizontal Falls form when the very high tide shifts through a gap in the ridges of the McLarty Range. The massive tidal movement builds up on one side of the narrow cliff passage, pushing through at rapid speeds to create the appearance of a waterfall, according to the Derby Visitor Centre.
In additional to being horizontal, the falls are also “reversible,” according to Western Australia's Department of Biodiversity, Conservation and Attractions. Each day, when the tide turns, the falls flow in the opposite direction.
