Snow often comes to mind when first thinking of Norway. Yes, it does snow a lot there, but Norway, along with all of Scandinavia, is also one of the most desirable countries in the world to live. But what really got our attention is the breathtakingly beautiful vast network of underground tunnels. There are more than 900 of them, 33 of which are underwater, and exceed a road length of some 466 miles (750 km). If you're not heading to Norway anytime soon, check out these tunnels here.
