Ennepetal: Caves, Water and Blacksmithing Culture

Kluterthöhle Cave and Heilenbecke Reservoir

The Kluterthöhle is the Ruhr region’s only National Natural Monument. It is also designated a National Geotope, and fossils are exceptionally well preserved on its walls. Guided tours explore some of its 380 passages. Options include standard tours as well as crawling and caving tours. The formats differ considerably: you can explore the cave on a classic guided tour or experience it differently on one of the tours explicitly described as crawling or caving. All available public tours and events at the Kluterthöhle can be booked online through the Ennepe-Ruhr district.

The Heilenbecke Reservoir is another distinctive feature: it is considered the oldest reservoir in South Westphalia. Together, the cave and reservoir represent two different sides of Ennepetal—the geological history beneath the earth and a landscape shaped by water.

Industrial History to See and Experience

At the Ennepetal Industrial Museum, the brick building itself tells a story of changing industrial uses. Originally built in 1890 for the production of wood screws, it served as an iron foundry from 1951 to 2005. The collection includes castings documenting the company’s history, models, tools, and photographs from its time as a foundry. The ceilings are supported by 60 cast-iron columns—a striking architectural detail that draws attention not only to the exhibits but also to the building itself.

The museum aims to present technology as a hands-on experience, particularly casting and blacksmithing. Other topics include the region’s mining history and machining processes. Blacksmithing is still carried out at Krenzer Hammer: the historic tool factory lies in the Ennepe valley and is Ennepetal’s last operating open-die forge. It produces specialist tools for a range of professions. Visits and guided tours on the art of blacksmithing are offered for schools and other interested visitors; under supervision, participants can make a small forged item. If you plan to take a tour or join in, check the date in advance.

Valley Views, Wildlife and Hiking Routes

In Hülsenbecker Valley, you can observe animals in wildlife enclosures, bird aviaries, and on the ponds. They include ducks, goats, donkeys, fallow deer, guinea pigs, and raccoons, as well as many other animals. If you would rather spend time outdoors than take a guided tour, Hohenstein viewing platform is another notable spot: built on a rocky slope, it offers views of the Ennepe valley and the Ahlhausen estate.

The “Sun, Forest and Water” hiking route runs from Klutertbad via Hülsenbecker Valley, Dorn, Niederhülsenbecke, the Uhlenbart car park, and Heilenbecke Reservoir to Niederklütingen, Filde, Herminghausen, Rüggeberg, and Willringhausen; it then returns to Klutertbad via Hülsenbecker Valley. The approximate walking time is six hours. The Handwerkerweg (Craftsmen’s Trail) is also described as taking approximately six hours: it runs from Voerde via the forest nature trail, Bilsteiner Kopf, the Ennepe valley, Krenzer Hammer, Finkenberger Mühle, Landbäckerei Hasenkehrmühle, and Hasper Reservoir, returning to Voerde.

The routes offer two different focuses. “Sun, Forest and Water” links places including Hülsenbecker Valley and Heilenbecke Reservoir with several named locations; the Handwerkerweg includes stops such as Krenzer Hammer, a mill, and Hasper Reservoir. Both routes take approximately six hours on foot. Bear this in mind when planning your day if you want to combine one of the longer hikes with a visit to the cave or museum.

More to Discover in the Ennepe-Ruhr District

The wider Ennepe-Ruhr district offers other experiences with their own character. You can hike and jog at Glörtalsperre; during the warm summer months, you can swim there in clean, natural water. In Hattingen, the “Iron Trail” at the LWL Industrial Museum Henrichshütte follows the process from ore, coke, and limestone to molten pig iron. A glass elevator takes you up to the 55-meter-high “Giant,” where you can look out over the region’s past and present. These regional options add to the selection without replacing what makes Ennepetal distinctive.

When looking for a holiday apartment in Ennepetal, you can first consider whether you want to focus your stay on caves and industrial heritage, wildlife and viewpoints, or longer hikes. Each of the routes described takes around six hours, offering a concrete estimate for two hiking days; the guided tours and museum offerings provide a different focus.
