Located in the southwest of Sweden, Lake Vänern (Vänern) is the largest lake in the European Union and the third largest lake in Europe. Only Russia has two even larger lakes. Over 22,000 islands, various nature reserves and partly untouched nature make this lake interesting and give an idea of the size of this body of water. Numerous canals, bridges and small tranquil towns make a trip around Lake Vänern an experience and an adventure.
A circumnavigation of Lake Vänern offers you over 600 kilometers of challenge and enjoyment. Take part and circle Lake Vänern on foot and earn the beautiful (and rare) Iron Lake MICRO Challenge collector's medal in the “Vänern” edition.
