Windsborn Crater Lake: A Unique Volcanic Wonder
Just 15.9 km (16 minutes) from Ferienhaus Auf Pötsch lies one of the most extraordinary natural phenomena in Europe: The Windsborn Crater Lake - the only permanently water-filled mountain crater lake north of the Alps.
A Geological Marvel
Unlike the famous Eifel maars (explosion craters), Windsborn is something different and even more rare. It's not a hollow form blasted into the ground, but rather the eruption crater of a volcanic mountain - part of the spectacular Mosenberg volcanic chain.
This makes it a true geological outsider and a must-see for anyone fascinated by Earth's volcanic history.
The Lake's Unique Characteristics
Scientific Profile:
- Elevation: 407 meters above sea level
- Crater Diameter: Approximately 150 meters
- Crater Depth: 45 meters
- Water Source: Exclusively rainwater (no underground springs)
- Water Color: Yellowish-brown
- pH Value: 5-6 (slightly acidic)
- Scientific Classification: Dystrophic brown-water lake
The lake's distinctive yellow-brown color comes from organic matter, and its acidic waters create a unique ecosystem home to rare plant species found nowhere else in the region.
A Living Laboratory of Nature
Rare Flora & Fauna
The Windsborn Crater Lake is a protected natural habitat hosting remarkable biodiversity:
In Spring (May-June):
- Thousands of white Bog Bean (Fieberklee) flowers carpet the water's edge
- The floating vegetation mat extends from shore into the lake
In Summer (June-July):
- Brilliant red Marsh Cinquefoil (Sumpfblutauge) blooms
- Countless dragonflies and butterflies dance above the water
- Ideal conditions for wildlife photography
Year-Round:
- Sphagnum mosses create floating mats
- Rare aquatic plants thrive in acidic waters
- The lake is slowly transforming into a high moor from the outside in
The Volcanic Landscape
Surrounding the crater, you'll find impressive welded volcanic slag - rocks that were ejected red-hot from the volcano and fused together as they cooled. These dramatic formations provide tangible evidence of the explosive forces that shaped this landscape.
Mosenberg Volcano Group
Windsborn is the fourth eruption point in the Mosenberg chain volcano group - one of the most fascinating volcanic complexes in the Volcanic Eifel. The entire area is part of the German Volcano Road (Deutsche Vulkanstraße), Point 37.
Hiking the Mosenberg Circuit
HeimatSpur Kraterseen Mosenberg Trail
- Distance: ~3 km circular route
- Duration: 1-1.5 hours
- Difficulty: Easy to moderate
- Elevation: Climb to 512 meters (Mosenberg summit)
- Highlights:
- Windsborn Crater Lake viewpoint
- Hinkelsmaar (another volcanic crater)
- Panoramic views from Mosenberg peak
- Geo-Route Manderscheid information panels
What Makes This Trail Special: This isn't just a walk through nature - it's a journey through geological time. Information panels along the Geo-Route explain the volcanic activity that created this dramatic landscape 10,000-30,000 years ago.
The Mosenberg Summit Experience
Climb to the 512-meter summit of Mosenberg volcano for:
- 360° panoramic views of the Volcanic Eifel
- Sight lines to other volcanic features
- Understanding of the chain volcano formation
- Perfect photo opportunities
- Interpretation of the volcanic landscape
On clear days, you can see the entire Mosenberg-Meerfeld volcano group stretching across the horizon.
