Valkmusa National Park

The driest and safest way to get out onto the bog is to walk around a special 2.5-km duckboard trail leading to a strategically placed bird-watching tower. Scan the marshes with your binoculars, looking out for dainty redshanks, whimbrels (with their characteristic long, curved beaks), orange-headed pochard ducks, majestic soaring ospreys, and huge but often strangely elusive cranes. During the spring and autumn large flocks of migrating cranes and geese flock to the bog, together with smaller flocks of local birders. Valkmusa has many different kinds of unusual marshland habitat of interest to ecologists. The park's many rare marshland butterflies include the purple-bordered gold. You can also watch dragonflies performing incredible aerobatic stunts over the bog as they hunt their insect prey. The cabin at Moronvuori Hill, overlooking the bog, is a good place to picnic or camp out. One of Finland's largest rivers, the Kymi, meanders along the northern edge of the park.
