LOCATED more than 100 metres underground in an old salt mine in Romania is an amusement park that looks like something out of space.

Salina Turda sits in the Romanian region of Transylvania and is one of the world’s oldest salt mines, dating back to the Middle Ages. Now a defunct salt mine, the area has been transformed into an amazing underground theme park with a ferris wheel, mini golf course, bowling lane, boating on the underground lake and a sports arena. Vertical shafts that once transported thousands of tons of salt will take you deep down in to the mine where you can tour its museum and the alien like structures. Offering a unique climate, the enclosed mine is free of allergens and bacteria making it perfect for sufferers of hay fever or asthma. At 80 per cent humidity it maintains a steady temperature of 11 to 12 degrees Celsius. Take a look inside the world’s deepest underground attraction.
