Hiking

The circular route takes you around the famous Hammerknuden rock formation on Bornholm for almost seven kilometers. The route is challenging because it is very rocky.

You can park on the beach in Sandvig and from there simply follow the blue dots that mark the path. Along the route you will not only pass the fascinating rock formation, but also the Hammerodde lighthouse, Salomon's Chapel and finally the Opal Lake.

What can I say?
WOW!!!!
Once again totally surprised, overwhelmed and fascinated!
Started from the campsite, then walked along the water for a while and was impressed by the rock formations, the power of the waves and the heather fields, there is just so much to discover and observe.
After a break with a view of Hammershus, we had a …

I can't contain myself: one of the most beautiful, varied, but also most challenging hikes of my life! The dominant colors are yellow = broom and blue = water. First past a few lakes, the second part, with the wind at my back, on the cliffs high above the Baltic Sea around the northernmost part of Bornholm. In between, a …

A beautiful route, the nature and the views are unique.
Be sure to stop at the kiosk in Hammerhafen, we fell in love with the St. Clemens sandwich there, it's so delicious. You have to wait a bit, but it's freshly prepared.
AND there are public/free toilets in Hammerhafen 👍

What a varied tour. Vertical rock faces, narrow paths and steep ascents and descents. Again and again views of the Baltic Sea, the Hammersee and a few smaller lakes 😍. An encounter with curious goats and a raven black mink. Sometimes you could only guess the way because heavy rain had washed away the tracks during the night.
But we …

Hammerkunden is Bornholm's northernmost corner. Consisting of granite, it was formed and shaped by wind and weather. And the glacier ice has also left its mark here. I'll take a look at that on a little hike.

Counterclockwise I follow the blue dot, the waymarker of the Hammeren Rundt. The loop starts at Sandvig Bay. Already here I am fascinated …
