On the 305 road Rudkøbing - Lindelse after about 6 km at your left. if you see the road to Herslev you have just overshot by 500 meters. As the Danish generally are very friendly you can no doubt park at the garden center nearby. In July 2015 there was no obvious path to the dolmens.
Something is not right. This message is just to keep things from messing up down the road
