The Old Aare – a fascinating river landscape between Aarberg and Büren. It is a valuable habitat for numerous animals and plants. People from near and far love and appreciate it as an attractive relaxation area. This unique idyll was created as a result of the first Jura water correction in the 19th century.

The observation tower is located in the Häftli nature reserve on the Alte Aare in the municipality of Büren an der Aare in the canton of Bern. The tower, made of wood, is 10.5 meters high. 36 steps lead to the viewing platform at a height of 7.5 meters. The platform offers a view of the birdlife of the Old Aare. So far, well over 200 species of birds have been recorded in the Häftli, almost 80 of which are breeding birds. A small breeding colony of night herons from 1967 to 1970 was unique in Switzerland. Since then, it has only appeared as a migrant and rare summer guest. Important breeding birds include little grebes and great crested grebes, black kites, water rails, kingfishers, lesser spotted woodpeckers, nightingales and orioles. The Häftli is an important wintering site for waterfowl, including several hundred teals, gadwalls and wigeons. Various species of herons, birds of prey, limousines and numerous songbirds can be observed as they pass through. The Häftli is also an important retreat for amphibians. So far, grass frogs, water frogs, tree frogs, common toads, natterjack toads, great crested newts, pond newts, mountain newts and fire salamanders have been identified.

From here you can enjoy a wonderful view of the Jura chain and the Häftli nature reserve, which is more than 10 meters below. Unfortunately, the stairs to the viewing platform are spiral-shaped and very, very narrow. Crossbreeding is not possible and people with a little more corpulence have a hard time here.

We hiked from the swimming pool in Büren a.A. over the footbridge on the "inside" of the loop. You can hardly see anything from the Aare. That's why we stopped halfway. Then try the part from Meienried or around the outside again. But we were welcomed in Büren an der Aare with a "holiday feeling" and enough time to stop!

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."
