Caves Beach is no misnomer. This magical beach is famous for the labyrinth of caves found at its southern end. They're only explorable at low tide, so be sure to time your visit according to the charts. 

Not to be confused with the aforementioned Caves Beach, Cave Beach is located on the other side of Sydney in Booderee National Park — about a three-hour drive south from Sydney. 

Contemplating a cave party? Pindar Cave might well be your first choice. It's an enormous overhang made of sandstone that can accommodate as many as 50 explorers at once. And you're perfectly welcome to stay the night. 

Strictly speaking, this isn't a cave. It's a 400m long, disused train tunnel that used to form part of the Wolgan Valley Railway. Glow Worm Tunnel may be rocky and dark, but there are stacks of glow worms hidden within. 

This is one of Ku-ring-gai National Park's most well-known sites for Indigenous heritage. On the Red Hands Cave walls, you'll see ochre handprints that have been there for thousands of years. 

Needless to say, we couldn't exclude this classic. In Jenolan Caves, 175 kilometres west of Sydney, you'll discover some of the most ridiculously beautiful rocks on the planet. 

Made of limestone, Palona Cave stands out in the mostly sandstone Royal National Park as it comes with exotic furnishings like stalagmites and stalactites. 

Like the Jenolan Caves, the caves in the Wombeyan Karst Conservation Reserve are a dazzling series of natural limestone structures. 

Even though River Caves is a canyon, you don't need abseiling skills to visit. All you have to do is walk in. That said, you can expect to get your knees — and maybe even your thighs — wet. 

This extraordinary structure is the creation of wind erosion. As a result, the walls are covered in tiny, intricate formations that have the colour and look of honeycomb. Being far taller than it is deep, it feels a bit like a giant's picnic spot.
