The reserve is an important refuge for the round-leaved sundew (Drosera rotundifolia), a carnivorous plant adapted to nutrient-poor bog environments.
The site is designated as a National Nature Monument, reflecting its high conservation priority.
The bog is situated at an elevation of approximately 800 meters above sea level.
It is one of the few places in the Czech Republic where specific rare mountain plant communities have survived due to the unique hydrological conditions of the peat bog.
The name 'Křížky' translates to 'small crosses', a historical reference to a local site feature.
Křížky is a protected peat bog nature reserve located within the Slavkov Forest (Slavkovský les) in the Czech Republic. It is primarily defined by the presence of a unique raised bog ecosystem that supports rare flora, including the endangered round-leaved sundew. The area is traversed by a wooden boardwalk path that elevates visitors above the fragile peat soil to prevent erosion and ecological damage. The site is a well-known habitat for the critically endangered Arnica montana and various species of protected orchids. It forms part of the larger network of protected nature reserves in the Karlovy Vary region. The landscape is characterized by a mix of coniferous forest and open wetland meadows. Signage throughout the area provides educational context regarding the specific biodiversity found in this highland peat moor.

Stick strictly to the wooden boardwalk to avoid damaging the delicate peat moss and plant life.
Bring binoculars for bird watching, as the open meadows attract various species of moorland birds.
Wear waterproof footwear if visiting after rainfall, as the surrounding forest trails can remain muddy.
Attempting to walk through the bog outside of the designated boardwalk, which is both dangerous due to deep peat and destructive to the ecosystem.
Stay on marked trails, do not pick any plants, and keep dogs on a leash at all times.
