Caves and gorges: Under and between Europe’s earth

September 24, 2025

Europe has countless natural wonders to offer, and some are deeply hidden. The continent’s caves and gorges are diverse, and there is something to discover underground in almost every country.

Here are 4 places that are sure to amaze you.

Eisriesenwelt Ice Cave (Austria)

Just south of Salzburg, Austria, lies the largest (known) ice cave in the world. Literally translated, its name means “the world of ice giants.” And it certainly lives up to its name. It is a huge cave consisting of a mixture of ice and rock. When you enter the cave, you can see bizarre ice formations and even frozen waterfalls.

Hardfacts:

  • Location: Werfen, Austria (40 km south of Salzburg)
  • Length: ~42 km (1 km with ice formations open to visitors)
  • Temperature: ~0 °C (32 °F) year-round

Škocjan Caves (Slovenia)

The Škocjan Caves are among the most impressive karst landscapes in Europe. In fact, they have been designated a UNESCO World Heritage Site since 1986. The caves were formed by the Reka River, whose force created various rock formations, while the humidity caused constant dripping.

Hardfacts

  • Location: Karst region, southwestern Slovenia
  • Length: ~6 km of passages (underground river canyon)
  • Temperature: ~12 °C (54 °F)

Partnach Gorge (Germany)

In a small town in Bavaria (Garmisch-Patenkirchen), the Partnach Gorge has cut deep into the surrounding rock. From a height of almost 70 meters, you can look down on the waterfalls and water vortex. In the summer months, the water sprays in all directions, and in winter, this causes the entire gorge to glisten with ice.

Hardfacts

  • Location: Garmisch-Partenkirchen, Bavaria, Germany
  • Length: ~700 m
  • Temperature: Varies with season; cool in summer, freezing with ice formations in winter

Wieliczka Salt Mine (Poland)

The Wieliczka Salt Mine is located in Poland, very close to Krakow. There are many things why this mine is so special. On the one hand it has passages in salt rock that are over 300 km long in total. And on the other hand People have also carved small chapels and sculptures into the rock, turning the mine into an underground salt cathedral. A mavel of human craftsmanship.

Hardfacts

  • Location: Wieliczka, near Kraków, Poland
  • Length: Over 300 km of tunnels (tourist route ~3.5 km)
  • Temperature: ~14–16 °C (57–61 °F) year-round
