The Florida Keys are probably one of the most fascinating and impressive island groups in the world. South of Miami begins the Overseas Highway, which leads to the paradise of the 40 islands and connects it to the mainland via bridges. To the left and right of the more than 200-kilometer route is not only a uniquely beautiful landscape with a lively, very traditional American culture. When diving in Florida on the Keys, every diver gets their money's worth: From Key Largo to Key West there is a coral reef and marine ecosystem that is second to none.
