Kesselgrotte, Natural sandstone grotto in Welzheim, Germany.
Kesselgrotte is a natural sandstone grotto featuring a waterfall dropping approximately eight meters into a basin below. The cavity spans roughly ten meters in width and seven meters in depth.
The grotto developed through gradual weathering and erosion of sandstone layers over millions of years, a process that shaped the Welzheimer Wald region. Water was the primary force that carved out these cavities naturally.
The grotto is part of an educational trail in the Schwäbisch-Fränkischer Wald Nature Park, where visitors can see and understand how water shapes sandstone layers over time. This site demonstrates how natural processes work in the region.
Access is via a marked hiking trail starting west of Welzheim that covers approximately two kilometers. Sturdy footwear is important because the path is uneven and becomes steep in sections.
A small creek from the Lettenstich area flows through the grotto and later joins other waterways in the region. This stream continues to shape the cave as it flows.
