Želízky is a small but striking nature reserve tucked into the Zimořský dol valley, where a roughly 400-metre stretch of sandstone rock walls creates a dramatic natural gallery. It's a rewarding stop for anyone who enjoys quiet trails, unusual geology and rare steppe flora rather than crowded viewpoints.

The south-facing sandstone cliffs create warm, dry habitats where the Bohemian meadow pasqueflower and goldilocks aster bloom in season, painting the slopes with colour against the pale rock. The northern part of the reserve is covered with acidophilic oak woodland dominated by sessile oak, offering shade and a cooler, more forested atmosphere. In autumn the reserve turns golden, while winter strips the landscape back to reveal the raw texture of the sandstone walls. Overall it's a peaceful, little-visited spot, ideal for nature photography and slow walking.

How to get there

• Dolní Zimoř or Sitná — yellow-marked trail through the Zimořský dol valley, easy walk, moderate difficulty depending on the section chosen
• Also reachable via cycling route no. 0010 connecting Dolní Zimoř and Sitná

Practical information

• Protected nature reserve — stay on marked paths and do not pick plants
• Home to strictly protected species including the Bohemian pasqueflower and leafless iris
• Numerous climbing routes are established on the sandstone walls
• Part of the Kokořínsko – Máchův kraj Protected Landscape Area

An interesting detail: after conservationists cleared invasive black locust trees from parts of the reserve, the rare leafless iris naturally recolonised the cleared ground — a small but telling sign of how quickly nature can reclaim lost territory.
