Strž ve Stupné

Strž ve Stupné is a small but strikingly scenic nature reserve located by the village of Stupná, right next to Vidochov, in the Jičín district of eastern Czechia. It takes the form of a deep erosion gorge cut into the hillside west of the lower part of Vidochov, dropping roughly 60 meters in elevation from west to east over a stretch of about 650 meters. The site combines both ecological and geological significance, drawing visitors interested in quiet nature walks as well as those curious about the region's rock formations.

What makes this gorge special?

The main reason the area was placed under protection is the presence of springs and natural ravines where the spring snowflake (Leucojum vernum) grows – a delicate, white-flowering bulb plant that blooms in early spring and is considered a marker species of protected wetlands and damp floodplain forests in Czechia. The moist gorge floor, fed by water seeping from the surrounding slopes, creates a distinctive microclimate that favors this kind of vegetation, which is scarcer in the drier parts of the surrounding forest.

What rock formations can be seen here?

Beyond its botanical value, Strž ve Stupné is also an important geological site. The deep gorge exposes conglomerates and sandstones of the Vrchlabí formation, dating to the Lower Permian period and forming part of what is known as the Stará Paka sandstones. These rock outcrops let visitors trace layers of sediment laid down tens of millions of years ago, and the site is valued by geologists and earth-science students as a natural cross-section through the geological history of the Podkrkonoší region.

How do you get there?

The reserve is accessible from the village of Stupná. A blue-marked tourist trail connecting Nová Paka and Borovnice runs along the lower part of the gorge, making it easy to work Strž ve Stupné into a longer hike through the area. The path follows the narrow, shaded gorge floor, flanked by steep, forested slopes, which keeps the walk pleasant even on warmer days.

What should you know before visiting?

As a protected natural area, general nature-conservation rules apply here: stay on marked paths, do not pick plants (including the protected spring snowflake), and avoid disturbing the geological outcrops. The site is overseen by the Nature Conservation Agency of the Czech Republic. Early spring, when the spring snowflake blooms, is a particularly good time to visit, although the gorge and its rock exposures are interesting to see throughout the year.
