Imagine stalactites shaped like needles, a series of eerily dark caverns, endlessly twisting passages and faint noises that sound like the crying out of a clawed creature in its depths. At Slovenia's Postojna Cave , you'll truly feel like Daenarys as you make your way through what was once, according to local tales, believed to have housed real fire breathing dragons. And as of this summer, these caves are in fact home to two new dragon babies. Make no mistake, this is no small hillside cave like the one Daenarys named Dragonstone. Some of the passages are 24 km long and two million years old, which takes visitors 1.5 hours to see a mere 5km. The tour includes venturing through such appropriately named places as the Beautiful Caves (named for its impressive ribbon-shaped stalactites), the Black Cave and the Winter Hall, which is where you can see the cave's most famous geological feature: a 5-meter high snow white stalagmite named the Brilliant.

However, the recent increase in visitors to Europe's largest show cave can be attributed to it's newest feature: the two new "dragon babies" that have recently hatched from 23 olm, or proteus, eggs. What makes them so special? Olms, an ancient aquatic salamander, are an endangered species exclusively found in Europe. Though they can live up to 100 years, the hatching of these dragon-like offspring is an incredibly rare event to witness as they only breed once in a decade.

If travelling like Games of Thrones means that you want to see some actual thrones, nearby Predjama Castle is a must-see. Perched high above the cave on the edge of a cliff, it is rumored that the castle's mysterious underground tunnels have offered refuge to many inhabitants, including the famous knight Erazem of Predjama, who is often referred to as the Slovenian Robin Hood, the robber baron. In 2008, the castle was officially deemed haunted after a visit from Ghost Hunters International . You can also sign up for the Royal Karst three-day tour, which includes two nights at the recently renovated four-star Hotel Jama , live Slovenian music, a visit to Predjama Castle, and the chance to meet the 'baby dragons' with a tour guide.
