Gillberga Gryte is a strange and exciting boulder area in the forest near Edebo. Here, large boulders are stacked on top of each other, forming cracks, passages and caves. The largest cave is around 137 metres long and is considered the longest in Uppland.
The boulder formation is about 80 metres long and 50 metres wide. The largest boulders can be up to eight metres high. Between the boulders, caves and gorges have formed, making the area an adventurous destination.
According to legend, the collapse occurred when a miner tried to blast his way into the mountain to open a mine but instead blew himself and the mountain to pieces. It is also said that the caves were used as a hiding place during the Russian raids in Roslagen in 1719.
