The ice tunnel which is being made in Langjökull, Iceland’s second-largest glacier, will be completed in a few weeks and are set to open in June and tourists will be able to experience the icecap from within. At 400 meters (1,312 feet), the ice tunnel will be longest in Europe, according to Iceland Review.

“We’re almost finished. I guess we have about ten days left of digging the tunnel itself, then there are some caves left and finishing touches … before we put up lighting and more,” Sigurður Skarphéðinsson, IceCave Iceland’s managing director, told Fréttablaðið.
