A challenging road through Jenolan Caves in the Blue Mountains

Okay, so you're heading to New South Wales? You HAVE to check out Jenolan Caves! I mean, we're talking the biggest and most famous caves in all of Australia. But get this – you can DRIVE through them! Seriously, it's one of the only roads *in the world* that tunnels through a cave.

You'll find these bad boys near Oberon, about a 3-hour trip west of Sydney, smack-dab in the Jenolan Karst Conservation Reserve. Think rolling hills and tons of protected wildlife.

Hidden on the southwest side of the Blue Mountains, Jenolan Caves are the most well-known limestone caves in Australia. People have been exploring them for over 150 years and they get about 240,000 visitors a year.

What makes these caves special? They're the pioneer of cave networks and have been developed as show caves for almost 200 years. While the number of available show caves changes, there were nine caves open for public viewing when initial records were made in the 1990s.

Don't miss Blue Lake, ringed by those incredible natural bridges like the Grand Arch! Oh, and keep an eye out for the blind white shrimp living in the underground waterways – talk about a unique critter!

Scientists figured out these caves are around 340 million years old, making them some of the oldest caves *ever*.

Now, the road itself, Jenolan Caves Road, is only about 150 meters long as it passes through the Grand Arch. But here's the thing: it's been through a LOT. Storms, fires, floods...it's seen it all! That means it's pretty narrow and can be tricky to navigate, so drive carefully! But the scenery? Totally worth it. Get ready for a wild ride!
