Iceland is famous for its glaciers but until recently, what lies underneath the Langjokull glacier had been a mystery. In 2010, the first manmade Glacier Ice Cave was carved to take people inside the heart of this remote glacier ice cap. What's more, you'll also visit the Deildatunguhver Hot Spring and Hraunfossar Waterfall.
Once you're kitted out after arriving at Husafell base, climb onto an especially modified snow truck to start the climb to the ice cave, exploring the rugged glacial landscape along the way. An experienced guide will lead the way inside, where the temperature stays at a constant, 0°. You'll see the magnificent blue ice buried deep beneath the surface.
All this combined with some bubbling hot springs, stunning waterfalls and panoramic views of the mountains as you make your way north to the glacier. You'll also enjoy dinner at a nearby restaurant. And on our return, you might – with luck – catch a glimpse of the Northern Lights dancing through the sky.
