Trehøje is a Danish vista point with a view of the sea to the east, south and west, located in the Mols Bjerge National Park on the peninsula Djursland between Denmark and Sweden.

[2] Today focused landscaping underlies the formation of the open plain-like grassland surrounding Trehøje, as well as other parts of the protected Mols Bjerge Hills.

This type of landscape occurred naturally in the Middle Ages, probably due to intensive grazing and repeated haymaking on the commons, combined with not bringing back the same amount of nutrients in the form of manure, as was taken away, according to a theory.

In some descriptions of the formation of the depleted vegetation around Trehøje there is no mention of the wind-erosion factor, which can blow away fertile topsoil nutrients – even though this has been a determining depletion-factor for surrounding land on Djursland in the Middle Ages.

In addition the wood-free open countryside is visitor friendly, giving opportunities for walks and biking on the paths and gravel roads surrounding Trehøje, as well as in the rest of hilly Mols Bjerge.
