Overview
Karlsöarna (Stora Karlsö and Lilla Karlsö) are two nature reserve islands west of Gotland in the Baltic Sea, offering one of Sweden's most dramatic wildlife spectacles. Stora Karlsö is the world's second-oldest protected natural area after Yellowstone, established in 1880, and harbors one of the Baltic Sea's most important seabird colonies.
