A beautiful valley with steep cliffs, pastures, and a wooden boardwalk. The walk around the valley also takes you above the valley through a gnarled forest with stunning paths and views down to the valley below. Down in the valley, you can expect to share the path with cows :-).

The castle ruins are the ultimate tourist attraction on the island of Bornholm. We were lucky that it was quieter there during the off-season. The view from the ruins is very beautiful, and the hiking trails surrounding them are also not to be missed.

Make a point to explore Hammershus Castle, the largest medieval fortress in Northern Europe. These impressive ruins sit above the Bornholm Coastal Path and are well worth the detour. Offering you breathtaking views of the sea and the surrounding landscape as you walk through the remains of the old walls and towers, you can almost imagine the castle in its prime. It served as a symbol of power and was a key part of the island's history. The panoramic vistas from here are perfect for a moment of quiet reflection.

A visit to the Hammershus castle ruins is highly recommended. The castle ruins offer a magnificent view. The Cafe Brohuset with its magnificent terrace opposite the castle ruins is also an absolute highlight.
