The tradition of clean books with a pen, stored in waterproof metal or plastic boxes, has spread from the climbing areas of German Saxony. It is possible to find them on interesting peaks, outlook towers or at the end of climbing routes.
The books are managed by regional tourist associations and individuals.

They are in two attractive places in the Sulov Rocks.

Pyskata Kacka / Kecka (822m a.s.l.)
