The Grane is a river of Lower Saxony, Germany. It is a right tributary of the Innerste river near Goslar. It rises in the vicinity of Hahnenklee in the Upper Harz and discharges about 12 km (7.5 mi) later into the Innerste near Langelsheim. At Herzog Juliushütte, in Astfeld (a district of Langelsheim) near Goslar, it is controlled by the Grane Dam.

The Innerste Dam (German: Innerstetalsperre) is a dam on the Innerste river, which lies near Langelsheim and Wolfshagen in the Harz mountains. It was built between 1963 and 1966 and belongs to the Harzwasserwerke. Its purposes are the supply of drinking water, flood protection, water flow regulation and hydroelectric power generation. The average annual discharge through the Innerste Dam is 60 million m³.

Hahnenklee is a borough of the city of Goslar, in the German state of the Lower Saxony. It is located within the Harz mountain range between Goslar and Osterode. The population is about 1200 inhabitants.

The formerly free mining town (Bergstadt) of Lautenthal in Germany is a state-recognised, climatic spa with around 1,570 inhabitants and has been part of the borough of Langelsheim since 1972.

The Grane Dam (German: Granetalsperre) is a dam above the village of Astfeld/Herzog-Juliushütte in the borough of Langelsheim in the Lower Saxon part of the Harz mountains.

Laute is a river of Lower Saxony, Germany. It is a right tributary of the Innerste. The Laute rises in the vicinity of Hahnenklee in the Upper Harz and discharges about 6 km (3.7 mi) later into the Innerste in Lautenthal. The source is at an elevation of about 540 m at the bottom of a mountain called Kuttelbacher Berg. The Laute flows to the west parallel to road L 516 which is called Hahnenkleer Straße in Lautenthal. The name of the town means Laute Valley. The mouth is at an elevation of about 300 m in the west of Wildemanner Strasse, the high street of Lautenthal. In 1875 a railway bridge of the Innerste Valley Railway was built over the Laute close to its mouth. Although the railway line was closed in 1977, the bridge is well preserved and still used by hikers. A flood of the Laute caused considerable damage in Lautenthal in 1877.

The Lutheran Gustav Adolf Stave Church (German: Gustav-Adolf-Stabkirche) is a stave church situated in Hahnenklee, a borough of Goslar in the Harz mountains, Germany. Construction of the church began in 1907 and it was consecrated on 28 June 1908. The church is a copy of the medieval Borgund Stave Church in Norway. It was erected during the sudden rise in Hahnenklee's popularity as a spa town and major tourist destination, with adaptions to fulfil its role as a parish church. The plans were designed by Karl Mohrmann (1857–1927), architect of the Evangelical-Lutheran Church of Hanover, a representative of the historicist Hanover school of architecture. He had visited Borgund and held the view that stave churches once were common in the medieval Saxon areas too. The church was built from spruce trunks harvested at the nearby Bocksberg mountain. The interior comprises numerous carvings of archaic symbols as well as Viking ship design features. The building soon became a frequently visited landmark and a popular wedding church.

The Lower Grumbach Pond (German: Unterer Grumbacher Teich), usually just Grumbach Pond (Grumbacher Teich), is an old mining reservoir or Kunstteich between Hahnenklee and Wildemann in the Upper Harz mountains in Germany It is one of the Upper Harz Ponds and was constructed before 1673. After being raised in height at least once, the dam today is 7.5 metres high and just under 60 metres long. There are nine other ponds within its catchment area, all part of the Upper Harz Water Regale: the Kranicher Teichen, the Kuttelbacher Teich, the Auerhahnteich, the Upper (Oberer) and Middle (Mittlerer) Grumbach Ponds and the Upper and Lower (Oberer and Unterer) Flößteich. Its catchment area is 7.92 km² which is very large for an Upper Harz Pond and results in a high volumetric flow. Its impoundment capacity is 82,000 m³.The pond was not only used for generating hydropower for the pits beneath, but also played an important role in timber rafting on the Grumbach stream to Wildemann. The timber, cut into one to two metre-long logs, was led by a rafting ditch around the pond and slid down the Gefluder in the present day Grumbach Waterfall into the stream. In order to transport the wood further downstream, water was periodically released from the Lower Grumbach Pond which ferried the logs down to the River Innerste.By the Lower Grumbach Pond is a refuge hut with checkpoint no. 113 "Grumbacher Teich" on the Harzer Wandernadel hiking network.

The Bocksberg is the local mountain for the village of Hahnenklee in the borough of Goslar in the German state of Lower Saxony. It lies southeast of this spa village in the Harz mountains and is 726 m above sea level (NN). It was from here that a 1,350 m (4,429 ft) long bobsleigh and racing toboggan run was laid in 1928, which had to be closed for technical and financial reasons in 1970. Although this mountain lay in the British Zone after the Second World War, the US Army operated a relay station here for their radio traffic between Frankfurt and Berlin. Its red and white transmission mast is used today for mobile telephone communications. It projects above the surrounding trees and is visible from a long way off. On the summit of the Bocksberg there is a restaurant and a wooden observation tower that was built in 1976.

The Kalte Birke is a cross tracks in the Harz Mountains of Germany where there is a refuge hut and former settlement. It is located west of the Innerste Reservoir at about 540 metres above sea level. It lies in the unincorporated area of Harz in the county of Goslar. Historically it is closely linked to the municipality of Hahausen and village of Neuekrug, four kilometres northwest.

The 435 m high Königsberg is a hill in the Harz mountains in central Germany, southwest of Goslar between the Grane Reservoir and the Steinberg. On its summit are the ruins of an old tuberculosis convalescent home, later a children's home, the Königsberg Sanatorium.
