Rettenwandhöhle

Rettenwandhöhle is a limestone cave in Thörl that stretches for about 600 meters through interconnected underground chambers at around 630 meters elevation. Natural passages carved by water flow over millennia reveal layered rock formations and natural architectural patterns created by geological processes.

The cave formed over millions of years as water gradually dissolved the limestone and created vast underground voids. Local people have known about this cave since ancient times, and later scientists studied its geological features to better understand Alpine formation processes.

The cave serves as a research location for geologists and naturalists who examine the mineral compositions and underground water systems of Styria.

Wear sturdy shoes since the ground is uneven and can be slippery in places, and bring warm clothing as the temperature stays between 4 and 6 degrees Celsius year-round. Contact local authorities beforehand to confirm access and current conditions before making the visit.

The cave contains untouched sections where mineral deposits look exactly as they did hundreds of years ago, unaltered by human activity. Visitors can observe natural underground processes here without the influence of tourism or development that affects many other caves.
