The Hübichenstein is an unusual rock formation in the Harz mountains, 50 meters in height, located on highway B242 about one kilometer northwest of Bad Grund, Lower Saxony, Germany. In 1897 it was crowned with a monument to Kaiser Wilhelm I, in the shape of an eagle with three-meter wingspan.

The WeltWald Harz (120 hectares) up to 2009 Arboretum Bad Grund, also known as Exotenwald and sometimes called the Arboretum des Forstamtes Grund or the Forstaboretum der Niedersächsischen Landesforstverwaltung, is an arboretum located along the B 242 federal highway near the Hübichenstein, northwest of Bad Grund, Lower Saxony, Germany. It is open daily without charge. The arboretum was established in 1971 by the Niedersächsisches Forstamt Riefensbeek (Riefensbeek office of the Lower Saxon Forestry Commission), with first plantings in 1975. By 1987 a total of 84,890 trees and shrubs had been planted on 65 hectares, including fir (30 species), spruce (25), maple (14), birch (10), and oak (8). Today it contains about 600 species of woody plants from Asia, Europe, North America, and Siberia, organized by geographic region, with a number of walking paths.

The Iberg is a hill, 563 m above sea level, in the western Harz mountains in the German state of Lower Saxony. It lies north of Bad Grund, above the Harz High Road. The Iberg is an old coral reef that emerged in the Givetian/Frasnian (Devonian) stages, that was created as an atoll in the middle of the ocean, probably from the base of a volcano. The reef was mainly built by corals und stromatoporoidea. Later, as the Frasnian transitioned into the Famennian, these reef-building organisms died out leaving the reef unfinished. During the Famennian and Mississippian crevices emerged that were filled with crinoid, brachiopod und goniatite chalks. The Iberg is made entirely of limestone and karstification has resulted in numerous caves. One of these, the Iberg Dripstone Cave is open to the public through guided tours. In the immediate vicinity is the Hübichenstein. On the northwestern slopes of the Iberg is a large limestone quarry and a lime works. On the summit is the Albert Tower (Iberger Albertturm) and a restaurant for day trippers. There is also a checkpoint (no. 130) for the Harzer Wandernadel. The Iberger Kaffeehaus on the northern slope was a popular restaurant and was also referred to as Bad Grund's Balcony (Balkon Bad Grunds). However it was the victim of arson on 28 February 2000 and has since fallen into rack and ruin.

The Iberg Dripstone Cave (German: Iberger Tropfsteinhöhle) is a public cave and geology museum in southern Lower Saxony near Bad Grund, Germany. It is located on the western edge of the Harz mountains in the 563-metre-high (1,847 ft) Iberg mountain at a height of 440 metres (1,440 ft) above sea level in the chalk of an upper Devonian atoll reef. The actual dripstone cave is 123 metres long. With its 78-metre-long (256 ft) Captain Spatzier Gallery, the Yellow Climb (Gelben Stieg) and two other caverns, the total length of the cave is 300 metres (980 ft). Between 2006 and 2008, the cave was turned into a 'cave experience centre' with the three main themes of "Fascination Cave" "The oldest family in the world" and "A reef on a journey".

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.
