Ekkodalen in the Almindingen forest on Bornholm is the island’s longest rift valley (abt. 15 kilometres or abt. 10 miles), and ranges about 2 kms through the forest Almindingen itself. And who knows? Maybe you are lucky enough to meet a bison in the forest as well?

When you are in the Allinge-Sandvig area, don't miss a trip to the Opal Lake. The lake is one of the oldest quarries on the island and definitely worth the trip. Bonus tip for a hot summer day: You can swim in the Opal Lake, but please note, that the lake is very deep – and therefore only suited for people, who can swim, as you won’t be able to stand on solid ground anywhere in the lake.
The Helligdomsklipperne (Sanctuary Cliffs) sits along the rocky coast between Tejn and Gudhjem, and are considered to be one of the most important landmarks not only of Bornholm, but in the whole Denmark.
