Penguins are some the fastest swimmers but when it comes to getting around on land, they are less graceful. Similar to the game trails, these highways help the clumsy birds get from their nests, which are often more than 100 meter high above sea level, to the ocean. Penguin highways are not wide and tend to be dug deep into ground from hundreds of penguins that use them.

I photographed this amazing scene when I made my trip to Antarctica in December 2017.
