This enormous (300m long) tunnel and series of caves head into Langjökull glacier at 1260m above sea level. The glistening, LED-lit tunnel and caves opened in 2015 and contain exhibitions, a cafe and even a small chapel for those who want to tie the knot inside a glacier. Tours can be had (March to October) from Húsafell or the glacier edge (Ikr17,900), or from Reykjavík (Ikr29,900) with the possibility of looping in the Golden Circle.
A maximum of 80 visitors at a time can travel up the glacier by monster truck, then have about 45 minutes touring the glacier – which will continue to creep down the mountain in the years to come.
