-What you can expect- 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 Hraunfossar Waterfall.After arriving at Husafell base, you'll climb onto a rugged snow truck to start your ascent to the ice cave, exploring the rugged glacial landscape along the way. An experienced guide will lead the way inside, where you'll see the magnificent blue ice buried deep beneath the surface that stays at a constant temperature of 0°.All this is combined with stunning waterfalls and panoramic views of the mountains as you make your way north to the glacier. And on our return, you might – with luck – catch a glimpse of the Northern Lights dancing through the sky.
