Lake Müllenborn – often called Müllenborner Weiher – is picturesquely located in the Müllenborn district north of Gerolstein and is a real insider tip for Komoot tours. The idyllic expanse of water, surrounded by cool forests, invites you to stroll, picnic, and enjoy mindful moments by the water. A beautiful, approximately 6km circular trail leads around the lake, past the historic millstone ruins and along the Oosbach stream – ideal for quiet explorations away from the hustle and bustle.
Around Müllenborn, you'll learn firsthand about the region's volcanic history: Oversized basalt blocks from the former Rother Kopf dominate the forest landscape, and you'll repeatedly encounter springs, small bridges, and the remains of old mills – hence the name "Mühlenborn" (Millsborn). The village itself, with its chapel and baroque houses on the shore, provides a charming, historic setting for the lake.
The lake is not open for swimming, but in summer, you'll often find locals cooling off or fishing here; provided you have a valid license. A visit to the Müllenborn Lake Festival in July is particularly atmospheric – with brass bands, a festival tent, and a convivial village atmosphere.
Just a few hundred meters away is the comfortable Landhaus Müllenborn, a 4-star country hotel with a spa, sauna, and sauna terrace – perfect for relaxing after the circular hike. The Eifelsteig trail runs nearby, and cyclists can also find connections to regional routes such as the Eifel-Ardennes Cycle Route.
