Tachovský vodopád, Natural monument in Troskovice, Czech Republic.

Tachovský vodopád is a natural monument about 200 metres southwest of Tachov, a part of Troskovice in the Semily district. An unnamed left tributary of the Jordánka stream has cut a valley into soft calcareous marls, forming travertine cascades and a waterfall roughly ten metres high where the stream drops over a wall of Teplice sandstone. The sandstone is coated with sinter, and a stalagmite about ten centimetres tall sits beneath the overhang.

Tachovský vodopád is a natural monument, registered under number 2268, in the care of the Český ráj Protected Landscape Area administration. Its protection covers a cascade of compact tufa, sinter coatings on quartz sandstone, rock perforations and small caves. The tufa holds embedded tree leaves and even pieces of municipal waste, showing that the formation is geologically young.

Spring snowflakes grow near the waterfall and are protected plant species important to Czech natural conservation efforts. These rare plants show why locals value this place for preserving local nature.

No marked trail leads directly into the protected area; the red-marked Zlatá stezka Českého ráje passes through Tachov, about 200 metres northeast of the waterfall. A local road from Troskovice to the Vidlák pond camp runs roughly 500 metres west, past the Krčák pond and the Podtrosecká údolí reserve boundary.

The travertine holds embedded tree leaves and even pieces of municipal waste, which shows the formation is geologically young. A stalagmite about ten centimetres across sits beneath the overhang of the waterfall.
