Nationalpark Kalkalpen is Austria's largest forest national park, renowned for its extensive beech and mixed forests, rugged limestone mountains, and rich biodiversity that offers exceptional hiking, wildlife watching, and nature immersion opportunities.
Nationalpark Kalkalpen, established in 1997, is located in the northern Limestone Alps in Upper Austria. It spans over 20,800 hectares of predominantly old-growth forests, steep limestone peaks, and deep river valleys. The park's geology is marked by its namesake Kalkalpen (Limestone Alps), featuring dramatic karst formations and cliffs rising above forested slopes. The ecosystem is characterized by dense beech forests, spruce, and fir trees, providing habitat for an array of wildlife including red deer, chamois, lynx, and the elusive Eurasian eagle-owl. The park's natural dynamics allow visitors to see how unmanaged forests and mountainous ecosystems evolve over time. In addition to forest ecosystems, wetlands and limestone caves are present, supporting diverse flora and fauna. Outdoor enthusiasts enjoy a comprehensive network of well-marked hiking and mountain biking trails, including routes to lookout points with breathtaking panoramas such as the Gmundnerhütte and Sengsengebirge ridge. Guided tours, educational programs, and visitor centers enrich the experience by focusing on conservation and Alpine culture. Winter presents opportunities for snowshoeing and cross-country skiing. The park plays a critical role in biodiversity conservation while promoting sustainable tourism, making it a premier destination for nature lovers and outdoor adventurers. The remote setting, combined with well-maintained infrastructure, draws visitors seeking both quiet wilderness and active recreation.
