About Ekkodalen Nature Reserve

Ekkodalen Nature Reserve
 

Ekkodalen Nature Reserve, located on the Danish island of Bornholm, is renowned for its dramatic geological features and rich natural environment. The reserve centers around Ekkodalen, the island’s longest rift valley formed by vertical cliffs of limestone and sandstone, stretching roughly 12 kilometers. These cliffs create a natural echo, which is the origin of the reserve’s name (Ekkodalen means 'Echo Valley'). The area is dominated by dense deciduous and coniferous forests, including beech and oak, providing habitat for diverse flora and fauna. Visitors often encounter native birds, deer, and intricate wild plant species throughout the reserve. Historically, the valley was a site of traditional sandstone quarrying, and remnants of this cultural past can be found along some trails. Recreational opportunities include hiking on well-maintained paths that wind through the valley and over its rocky escarpments, providing panoramic views of the surrounding landscapes and Baltic Sea on clearer days. The reserve is favored by walkers for its peaceful environment, natural acoustics, and scenic diversity, including small streams and caves. Visitors can also learn about local geology, botany, and cultural history through informational signage. Ekkodalen offers an accessible but immersive outdoor experience with moderate trails suited to families and more experienced hikers. Its combination of natural features and cultural heritage makes it one of Bornholm’s premier nature destinations.
