2. Vatnajokull Glacier Cave, Iceland
Vatnajokull Glacier, also known as Vatna Glacier, is one of the most breathtaking products of nature, but the caves that have formed beneath the glacier are even more beautiful. Located in the south-east part of the island, the glacier covers more than 8% of the country. Vatnajokull is the largest ice cap in Europe with an area of 8,100 sq.km and was first formed from a volcanic eruption that took place in November 1996. The eruption melted billions of gallons of ice and formed a jewel-like cave interior that leaves adventurers astonished.
