The region contains rare mofettes, which are volcanic vents that emit carbon dioxide instead of steam.
Kladská, a primary highlight, was established in the 19th century as a hunting estate by Prince Otto Friedrich von Schönburg-Waldenburg.
The forest hosts the rare Arnica montana, a medicinal plant protected within the reserve.
Several areas of the forest are strictly protected due to the presence of endangered peat-bog ecosystems.
The landscape bears scars from medieval tin mining, visible today as artificial mounds and depressions known as 'pingen'.
The bedrock of the Slavkov Forest is significantly older than the surrounding volcanic formations of the Doupov Mountains.
Slavkov Forest (Slavkovský les) is a protected landscape area in western Czechia, covering approximately 610 square kilometers. The terrain is dominated by a crystalline core of granite and gneiss, characterized by plateaus and deeply incised river valleys. It is geographically positioned between the spa towns of Karlovy Vary, Mariánské Lázně, and Františkovy Lázně. The reserve features unique geological phenomena, including cold carbon dioxide mineral springs and mofettes. Historically, the area was heavily influenced by tin mining, which left behind unique anthropogenically altered landscapes. Significant ecological sites include the Kladská peat bog and the nature reserves Smraďoch and Milhostovské mofety. The forest provides a complex network of marked hiking and cycling trails that traverse diverse woodland and wetland habitats.
The wooden boardwalks crossing the Kladská peat bog during early morning mist.
Wear waterproof hiking boots, as the trails surrounding the peat bogs can be muddy or boggy.
Bring binoculars for wildlife spotting, as the forest is home to red deer, mouflon, and diverse bird species.
Download offline maps before arrival, as cellular reception is inconsistent in the deeper valleys.
Do not attempt to traverse off-trail areas near mineral springs or bog zones, as these are unstable and ecologically protected.
Stick to marked trails to protect sensitive peat bog ecosystems; picking plants is strictly prohibited.
