Deception Island

"Deception Island is a large island formed of a caldera. Inside of the caldera is the famous Whalers Bay, one of the largest land-held whaling stations in the 1900s. During its heyday, it's said that you could see 3500 whale carcasses floating in the caldera bay at one time. Around the outside of the bay, you'll find Baily Head, the world's largest chinstrap penguin colony. Within the valley of Baily Head, which is incredibly beautiful even without the penguins, during the right season, you'll see thousands of chinstrap penguins covering every surface of the valley."
