The Halterner reservoir, officially called "Stevertalsperre" is one of the most popular local recreation areas in the Ruhr area.

While large areas of the region were still covered with heathland at the beginning of the 19th century, today the Westruper Heide is a remnant of that time. The approximately 90-hectare heath is in the immediate vicinity of the Haltern reservoir.

The Hullern reservoir is the Stever dammed for drinking water production. This lake only has a "sandy beach" during long periods of drought, like here in August 2022. The SteverLandRoute runs along the banks of the Hullern and Halterner reservoirs and offers beautiful views of the lake from the cycle path, which is otherwise inaccessible. The fourth stage of the Steverland route always leads along the shore of the lake. The SteverlandRoute is the family bike path in Münsterland. Take a look at our collection! :)

Definitely stop off at the Jupp am See to linger over coffee and cake or a currywurst. Next door is also a great climbing garden for young and old.

With its important past as a Roman base around the birth of Christ, Haltern am See has had town rights since 1289 and is a historical, up-and-coming medium-sized town, located at the northernmost point of the Lippe, embedded in the Hohe Mark, Haard and Borkenberge forest areas. The current urban area of Haltern am See was created as part of the municipal territorial reform in North Rhine-Westphalia in 1975. At that time, the town and the Haltern district, consisting of the communities Kirchspiel-Haltern (Holtwick, Lavesum and Sythen), Hullern and Lippramsdorf, were merged and expanded south of the Lippe to include the communities of Flaesheim (formerly part of the Datteln district) and Hamm-Bossendorf (parts of the Hamm community formerly part of the Marl district). The allocation of districts south of the Lippe to Haltern meant crossing a centuries-old border. A border that was the reason and prerequisite for the granting of town rights to Haltern by the sovereign and Prince-Bishop of Münster, Everhard von Diest, in the 13th century. Since 1908, Haltern am See has had a pumping station to pump drinking water for the northern Ruhr area. Water extraction has been steadily expanded; it helped the city to earn its decorative name "Haltern am See" and reached its provisional end point with the completion of the Hullerner Lake in 1985. A side effect of the area-intensive water management is the increased recreational value of the Haltern landscape, which, free of industry, has become even more attractive to visitors and locals thanks to the creation of the lakes. Today, the Haltern lakes with their boathouses, sailing harbor and seaside resort are the destination of many people seeking relaxation. But Haltern am See has more to offer visitors than just the lake. The attractive and varied landscape is often referred to as the lungs of the Ruhr area. The city is the heart of the Hohe Mark Nature Park. The extensive forests of the Haard and the Hohe Mark, as well as the Westruper Heide, Holtwicker Heide and Sebbelheide nature reserves, are accessible via a dense network of hiking, cycling, horse riding and walking trails. The pedestrian zones of the old town and the modern town centers of Sythen, Flaesheim, Lippramsdorf, Hullern and Lavesum are popular shopping and meeting places for residents and visitors alike.

The Old Ride is a disused section of the Dortmund-Ems Canal. The 8 1/2 km long section extends from the Datteln canal junction to behind Olfen. A beautiful footpath and cycle path leads directly along the water.

Beautiful section of the route in the direction of Olfen. You should definitely drive down along the water (not up on the road) to really enjoy it.
