One of the great wonders of the natural world, the Horizontal Waterfalls are a phenomenon created by massive tidal movements of up to 10 metres difference between high and low tides on the huge Montgomery Reef, Australia’s largest inshore reef in Talbot Bay. These turning tides form a rushing waterfall effect between the water banks, best seen on a fast boat as you zoom through. Or spot rock wallabies perching on rocky outcrops along Cyclone Creek on a zodiac excursion.
