Iceland is famous for its glaciers, but until recently, what lies underneath Langjökull, Iceland's second-largest 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. Local guide Árni explains, "Most visitors come for the glacier, but Hraunfossar is one of those places Icelanders never tire of. The water has travelled underground through lava for centuries before appearing here."
After arriving at Húsafell 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 blue ice buried deep beneath the surface that stays at a constant temperature of zero degrees. Walking through the tunnels offers a rare chance to witness the layers, textures and colours hidden within one of Iceland's largest glaciers.
All this is combined with stunning waterfalls and panoramic views of the mountains as you make your way north to the glacier. And on the return, you might – with luck – catch a glimpse of the Northern Lights dancing through the sky, providing a memorable finale to a day spent seeing some of Iceland's most remarkable natural wonders.
