From the castle, only a small remnant of a wall in the rock on the hill remains. Otherwise, it's more of a castle site. However, the impressive, striking rock formation next to it is notable.

Your next hiking route: From Burdorf via the individual Fluen in the direction of Hasle and then in the direction of Emme and Emmenweg back to Burgdorf. This route is super beautiful and includes almost everything. Dirt road, short steep climbs, longer flat sections, a river and lots of nature. Everything a hiker's heart desires.

At this point there is a sandstone pit, which can be accessed from the back through a tunnel. In the pit there is a fireplace and various wooden chairs made from tree trunks. In the summer a shady place to grill. "You enter the pit through a tunnel that the users once excavated. Mining began in the 16th century. At that time, a lot of millstones were needed, a pit near Oberramsern could no longer meet the demand. This was the decision of the Great Council of Solothurn In 1527 a local miller was commissioned to quarry stone near Ober Bockstein on its land. After a few years, however, the miller gave up, as it turned out that his sandstone was too soft for millstones. In 1777, operations resumed in the Upper Bockstein Bockstein-Grube. Above all stove plates were now made from the sandstone. The last stone carver, the "Grubendurs", lived with his wife, the "Grubenänni" until 1890 on site, where the two had set up makeshift in a cave-like niche, as stated on the information board."

Much visited bike path. Beware of many pedestrians. If you want to go fast, you'd rather drive on the main road, with a lot of traffic.

Well-known vantage point in Affoltern in the Emmental at 890 m above sea level. This used to be a so-called Hohwacht on which an alarm fire was lit in the event of war.
