The World Heritage listed Blue Mountains are just two hours from Sydney and home to some of the best hiking in Australia. We guess there's a reason we run so many hikes there right?! Here is our pick of the best hikes in the area.

When most people think of the top things to see in the Royal National Park near Sydney, they tend to think of the Figure 8 Pools or the Wedding Cake Rock. But one of the most underrated natural wonders in the Royal National Park along the Sydney Coast Track is Curracarrong Falls, a waterfall right next to Eagle Rock.
Most waterfalls are formed in the upper sections of a river in steep mountains, but what makes Curracarrong Falls so unique is that it empties out directly out into the Pacific Ocean. Think about it, where else in the world have you seen a waterfall that drops directly into the ocean?
Wikipedia suggests that there are only 30 areas with coastal waterfalls, also known as tide falls, like this in the world, making them incredibly rare. In Australia, the only other recorded coastal waterfall is in Waterfall Bay in Tasmania. The rest are scattered around the world in places like Mealt Falls in the Isle of Skye, or McWay Falls in California. But surely there must be more? After all, how much can we really trust Wikipedia :)
In a recent publication in the journal Geomorphology, two US scientists Patrick Limber and Patrick Barnard state that coastal waterfalls with constant flow are relatively uncommon and there is no broad explanation of how they develop and evolve.
They suggest these coastal waterfalls are caused by a unique interplay of marine and terrestrial processes. Essentially, the horizontal erosion of the landscape caused by the impact of ocean waves (which forms sea-cliffs) has occurred at a faster rate than the erosion/incision of the earth through rain water. For this to happen, you will generally need to be in a place where the sea-cliff is retreating rapidly and wave energy is high, while the flow of water is relatively small.
