Deception Island

From Wikipedia:

Deception Island is an island in the South Shetland Islands off the Antarctic Peninsula in Antarctica. It is notable for having one of the safest harbors in Antarctica, and for being an active volcano, whose eruption in 1970 caused serious damage to the scientific stations there.

Deception Island has several colonies of chinstrap penguins, and it is possible to make a warm bath by digging into the sands of the beach, so it has become a popular tourist stop in Antarctica.
