Exploring the Postojna Cave in Slovenia

Standing in a cold and damp underground chamber, I prepared to descend into the darkness below.

Dressed in an unflattering but protective orange jumpsuit, boots and a hard hat, I climbed over the barrier, positioned myself on the edge of the ledge and leant back into my harness.

I then slowly fed the rope through my hands, lowering myself deeper into the earth’s centre.

This was not my first time abseiling, but it was my first time doing it in a cave.

And while I understand this might not be everyone’s cup of tea, I was in my element.

I had travelled to Slovenia to explore the Postojna Cave – the largest cave system in Europe and the country’s top tourist attraction.

The stunning natural phenomenon was carved by the Pivka River thousands of years ago and is 24 km long - three kilometres of which were only uncovered earlier this year.

For my adventure I had ventured into the smaller Pivka Cave to follow in the footsteps of explorer Luka Cec, who discovered part of this beautiful hidden world in 1818.

As well as abseiling, the tour includes pulling yourself across the river in a rubber dinghy, sliding down a mud hill, setting up a carbide lamp and climbing caves walls.

It is perfect for any adrenaline lovers out there, who as well as testing themselves also want to see one of the world’s most breath-taking and virtually untouched landscapes.

The Postojna cave isn’t just for the adventurous however.

This cave is the only one in the world that can boast a double track railway, allowing guests to travel into the oldest parts in style and with ease.

Two kilometres in, you are free to explore the many tunnels, passages, galleries and halls by foot, including the concert hall - where bands and orchestras often play - and tube hall.

There are stalagmites, stalactites and formations called ‘curtains’ at every corner, with one 16ft stalagmite known as ‘The Brilliant estimated to be around 100,000 years old.

This cave is also home to the mysterious proteus, also known as the human fish. This small aquatic salamander is completely blind and can live for up to 100 years.

They are only found in Central and Southeastern Europe, and can be seen in the Pivka River or in the vivarium at the end of the tour of the Postojna Cave.

When you’re ready to resurface, make your way to Predjama Castle - the Guinness World Record Holder for the largest cave castle in the world.

The 700 year old building is perched in the middle of a 123 metre high cliff and sits above the second longest cave in the country.

It is in this cave where you will see bats in their natural habitat.

As much as caving was the highlight of my three day trip, Slovenia has others things to offer.

The capital, Ljubljana, is only a short drive from Postojna, and is known for its impressive architecture and countless hidden gardens.

Next year is the 25th anniversary of Slovenia’s independence, making it an exciting and perfect time to visit as there will be celebratory events running throughout the year.
