Mondmilchhöhle, Natural cave entrance in Lenningen, Germany.
Mondmilchhöhle is a natural cave near Lenningen formed by water dissolving limestone, with multiple chambers containing stalactites, stalagmites, and moist rock surfaces. The passages descend into the mountain and display natural formations throughout.
The cave formed over millions of years as water seeped through limestone and slowly carved underground spaces. The region was known for a long time, but only in modern times was it made accessible for visitors.
The cave takes its name from moonmilk, a rare white mineral deposit that forms on the walls and glimmers in the damp environment. Visitors encounter this natural phenomenon firsthand while walking through the passages.
The ground is wet and slippery, so suitable shoes with good grip are important for your visit. Temperature inside the cave stays cool year-round, so bring a jacket along.
The name comes from a rare mineral substance called moonmilk that grows in the cave and glimmers white under light. This mineral is seldom found in many caves and makes this location distinctive.
