The Harz rises out of the north German plain with an abruptness that feels deliberately theatrical — as though the landscape wanted to make a point about being different. To the north and east, the plain extends flat to the Baltic; to the west, it continues flat toward the North Sea. And then, from roughly 150 m above sea level, the Harz climbs steeply to the Brocken summit at 1,141 m, covered in dense forest, thick with legends, and marked by a history that encompasses medieval silver mining, Goethe’s metaphysics, Nazi ideology and Cold War espionage in roughly equal measure.

Geography and Structure
Upper and Lower Harz
The Upper Harz in the west is the wetter, higher and more forested section — annual precipitation on the Brocken reaches 1,800 mm, one of the highest figures recorded anywhere in northern Germany. The Lower Harz to the east is gentler, with broader valleys, more mixed land use and a milder climate. The contrast between these two sections — the austere highland in the west and the more open, humanised eastern slopes — is part of what makes the Harz so varied.
The Karst South
The southern Harz conceals a karst landscape of limestone caverns, sinkholes and underground drainage systems. The Baumannshöhle and Hermannshöhle at Rübeland are two of Germany’s oldest open show caves, first made accessible to paying visitors in the 16th century. The caves contain Ice Age deposits including cave bear remains and are genuine natural history archives.
The Brocken – Mountain of Myths
Why the Brocken Is Famous
The Brocken (1,141 m) is the highest point of the Harz and one of the most mythologically loaded mountains in Germany. It is not especially tall, not particularly dramatic in form, and not technically challenging. What it has is atmosphere: it stands above the tree line, frequently engulfed in cloud (an average of 306 fog days per year), isolated from the surrounding forest, and visible from an enormous distance across the flat northern plain. These qualities attracted both legend and logistics.
Goethe’s Brocken
Johann Wolfgang von Goethe climbed the Brocken several times and immortalised it in Faust, where the mountain serves as the stage for the Walpurgisnacht — the witches’ sabbath on the night of 30 April. Goethe’s first ascent in 1777 was partly philosophical reconnaissance: he was interested in the Brocken Spectre, an optical phenomenon where a climber’s magnified shadow is projected onto cloud or fog below, surrounded by a rainbow-like halo — a natural spectacle that had been interpreted as supernatural for centuries.
The Brocken as Cold War Infrastructure
Between 1945 and 1989, the Brocken was closed to the public. The GDR military and Soviet intelligence services operated a major signals intelligence facility on the summit, bristling with antenna arrays capable of monitoring communications across much of West Germany. The powerful transmission towers on the summit — still visible today — were part of this system.
When the Wall fell on 9 November 1989, residents of Wernigerode and other Harz towns marched to the Brocken the following day and tore down the border fences, making the Brocken one of the most symbolically immediate acts of German reunification.
A Thousand Years of Mining
Silver, Copper and Wealth
Harz mining history is not ancient — it is millennial. Silver was being extracted near Goslar as early as the 10th century under Emperor Otto the Great. By the 16th century, the region around the Rammelsberg was one of the most productive ore bodies in Europe. The silver and copper revenue underwrote the ambitions of successive Saxon rulers and made Goslar one of the most significant imperial cities in the Holy Roman Empire.
The Upper Harz Water Management System — UNESCO World Heritage
The Oberharzer Wasserregal is one of Europe’s most ambitious pre-industrial engineering systems. Built and expanded between the 16th and 19th centuries, it consists of over 100 artificial ponds, 500 km of drainage channels and 30 km of tunnels — designed to store and direct water to power the machinery of the mining industry. The system still functions today, now providing drinking water and flood management. It was designated a UNESCO World Cultural Heritage site in 2010.
Goslar — Imperial City of the Silver Rush
Goslar is the most complete medieval mining city in Germany. Its market square, dominated by the Kaiserworth merchants’ house and the Gothic town hall, looks much as it did in the 15th century. The city, together with the Rammelsberg mine and the Old Town, has been a UNESCO World Heritage site since 1992. More than 20 Imperial Diets were held here — the city was, for a period, effectively the capital of the Holy Roman Empire.
Harz National Park — Wilderness in Progress
One Park from Two
The Harz National Park (247 km²) was formed in 2006 by merging the former GDR national park (established 1990) with the existing Lower Saxony Harz national park. It is the only national park in northern Germany and the second-largest in the German uplands.
The Bark Beetle and the New Wilderness
The park’s management through the bark beetle outbreak of the 2010s became one of the most watched and most debated conservation experiments in Germany. As drought-weakened spruce died across the park in vast numbers, the management team — resisting intense political pressure — declined to intervene. Dead trees were left standing.
The results are becoming visible: where spruce monoculture stood, a structurally diverse, species-rich pioneer forest is emerging. Birch and rowan are the first colonisers; in their shade, fir and beech seedlings are establishing. Ornithologists are recording species not previously found in the area; invertebrate surveys show explosive increases in dead-wood-dependent beetle communities.
The Narrow-Gauge Steam Railway
Three Lines — One Continuous Network
The Harzer Schmalspurbahnen (HSB) operates 140.4 km of narrow-gauge railway — the largest connected narrow-gauge network in Germany still operating regular steam locomotive services.
- Harzquerbahn — Nordhausen to Wernigerode (60.5 km)
- Selketalbahn — Quedlinburg to Eisfelder Talmühle (56.5 km)
- Brockenbahn — Drei Annen Hohne to Brocken summit (19 km)
The Brockenbahn is the most celebrated: a steam train that chugs and whistles its way through forest, over open moorland and into the cloud-shrouded summit zone — in operation since 1899 and running in all weathers throughout the year.
Walpurgis Night and Folklore
30 April on the Brocken
Every year on the night of 30 April, tens of thousands of people celebrate Walpurgisnacht across the Harz — with particular concentration on the Hexentanzplatz (Witches’ Dance Floor) at Thale and on the Brocken itself. The tradition conflates pre-Christian spring celebrations with medieval witch-hunt hysteria and Goethe’s theatrical appropriation of both.
The Harz narrow-gauge railway runs special services all night; the summit is packed with people in witch and devil costumes; bonfires are lit in villages across the range. The combination of historical resonance, literary heritage and organised tourism makes Walpurgisnacht uniquely Harzian.
Walking and Tourism
Harzer Hexenstieg
The Harzer Hexenstieg (100 km, Osterode to Thale) is the Harz’s signature long-distance walking route. In five to seven days it crosses the range from west to east, ascending the Brocken and descending into the dramatic Bode valley before reaching Thale and the Hexentanzplatz.
Quedlinburg — Romanesque Masterpiece
Quedlinburg on the eastern Harz edge contains one of Germany’s finest ensembles of Romanesque architecture. The Collegiate Church of St. Servatius, standing on a sandstone plateau above the town, is the burial site of King Henry I and Abbess Mathilde — the founders of German kingship. It has been a UNESCO World Heritage site since 1994.
FAQ
What is the highest point of the Harz? The Brocken at 1,141 m — also Germany’s northernmost significant summit.
Why was the Brocken closed during the Cold War? The GDR military and Soviet intelligence services operated a major signals intelligence facility on the summit between 1945 and 1989, monitoring West German communications. The first civilians reached the summit on 10 November 1989 — the day after the Wall fell.
What is the Upper Harz Water Management System? A pre-industrial engineering system of 100+ ponds, 500 km of channels and 30 km of tunnels built from the 16th century onward to supply water power to the mining industry. Designated a UNESCO World Heritage site in 2010 — one of the finest examples of pre-industrial hydraulic engineering in Europe.
