The ruins near Kluk are one of those rare finds that reward the curious hiker — a forgotten rock castle tucked into the woods of the Kokořínsko region, so obscure that even historians only discovered its remains in 1990. There are no grand walls to admire here, just the quiet thrill of stumbling upon something genuinely hidden from the guidebooks.

The landscape is classic Kokořínsko sandstone country — rocky outcrops, narrow clefts, and dense forest that keeps things cool in summer and reveals more of the terrain's shape once the leaves fall in autumn. The atmosphere is intimate rather than grand; this isn't a place for crowds, but for a peaceful walk among sandstone rocks where only a careful eye will spot traces of the old fortification.

How to get there

• From Dubá — around 4 km southeast, moderate difficulty, wooded and rocky terrain
• From the hamlet of Kluk (part of Dražejov) — the shortest approach, sturdy footwear recommended due to uneven ground

Practical information

• Only fragments of dry-stone walls and a depression marking the former building have survived
• No marked trail leads directly to the ruins — some route-finding skill is needed

The castle doesn't even have a known name — it left no written record, and its existence was revealed only through pottery finds dating its construction to around the mid-13th century. A quiet corner of history, waiting for those willing to look closely.
