About
Lake Mälaren is Sweden’s third‑largest freshwater lake, stretching 120 km from the east coast of Stockholm to the interior of the country. With a surface area of 1 140 km² and a maximum depth of 64 m, the lake has long been a natural artery for trade, culture and recreation. Its many islands—Selaön, Svartsjölandet, Björkö, Ekerö and others—are dotted with historic sites, beaches and nature reserves. Mälaren is famed for its rich biodiversity: over 30 native fish species, large populations of swans and geese, and a thriving ecological corridor connecting the Baltic Sea and inland waters. The lake’s shores have inspired artists and writers for centuries, and its waters remain a popular destination for sailing, kayaking, fishing and scenic drives. Whether you’re exploring the Viking‑age ruins of Birka, touring the palatial grounds of Drottningholm, or simply taking a leisurely swim in its tranquil bays, Lake Mälaren offers a unique blend of natural beauty, historical depth and modern leisure.
