Norway's first marine national park protecting the skerry archipelagos of eastern Oslofjord

Ytre Hvaler National Park

Ytre Hvaler National Park is Norway's first national marine park, established in 2009 to protect the dramatic outer skerry landscapes of the eastern Oslofjord coast. Located within Hvaler and Fredrikstad municipalities in Østfold county, the park encompasses a network of islands, islets, and surrounding marine waters that form one of Norway's most distinctive coastal wilderness areas. The park covers 354 square kilometers, with the overwhelming majority—340 square kilometers—being marine environment, making it fundamentally different from Norway's mountain and forest-dominated national parks. The park's significance extends beyond its marine focus to include significant cultural heritage. Settlements in the area date back to the Bronze Age, and the islands have supported coastal communities for centuries. The landscape is characterized by exposed rocky islands, sheltered inlets, and productive fishing waters that have sustained maritime communities. Two historic lighthouses—Torbjørnskjær and Homlungen—mark navigation points that have guided sailors through these challenging waters for generations. What makes Ytre Hvaler particularly remarkable is the presence of the Tisler Reef, the largest known cold water coral reef in sheltered waters in Europe. This reef, dominated by the coral species Lophelia, represents a biological treasure that draws scientific attention from across the continent. The park also contains over fifty documented shipwrecks, including the Danish frigate HDMS Lossen lost during the Christmas Flood of 1717, adding maritime archaeological significance to its natural values.
