From the Altarklippen you have a wonderful view over the Granetalsperre to the Rammelsberg. For me it is one of the top 20 stamping points for the Harz hiking pin. The path up to the Altarklippen is easy to do - even by bike.

The Innerste Dam offers many opportunities for sporting activities. You can walk around it, by bike or rollerblades and many water sports are possible and permitted. A wonderful local recreation area! Culinary delights are provided in the middle of the dam and an ice cream van is parked at the dam wall during the season. The path around the Innerste Dam is asphalted and ideal for cycling. There are also many opportunities to turn off into the forest from the dam and extend your tour. Or you can continue on the Innerste cycle path to Lautenthal or Langelsheim.

The dam was built between 1963 and 1966 and has since dammed the Innerste river. Behind the dam, which is about 35 meters high and 750 meters long, is an artificial lake that is up to three kilometers long. The reservoir is a popular destination for nature lovers.
