Two large, glittering lakes rest in the center of the Punkaharju Nature Reserve. Majestic pine trees and easy walking paths make the park one of the most visited locations in Finland. One of the oldest nature reserves in the world, Punkaharju is home to many animals, including foxes, muskrats and badgers. (KEN GILLHAM —ROBERT HARDING PICTURE LIBRARY LTD/ALAMY)
