Perched on the rocky plateau of Zámecký vrch at 681 metres above sea level, the ruins of Adršpach Castle are a fascinating hidden gem just two kilometres west of the village of Adršpach. Founded most likely by King John of Bohemia in the early 14th century, this former royal stronghold has a turbulent story — and wandering among its moss-covered walls feels like stepping straight into the Middle Ages.

The atmosphere here is wonderfully raw and untamed. Fragments of masonry emerge from the rock face, corridors carved directly into the stone hint at the castle's complex layout, and the surrounding forest keeps the ruins wrapped in quiet mystery. In spring and autumn, low mist drifts between the trees and gives the place an almost ghostly feel. In summer it offers a cool, shaded escape from the busier trails of the nearby Adršpach-Teplice Rocks.

• Village of Adršpach (car park near the Rock Town entrance) — forest path heading west, approx. 2 km, easy to moderate difficulty.

• The ruins are a protected cultural monument of the Czech Republic.
• The site is unfenced and free to visit.
• Take care around loose masonry and slippery rock ledges.

The castle met its end in 1447 when Silesian and Lusatian towns paid 900 Hungarian gold coins to buy it from its owner and promptly had it demolished — fed up with the garrison's raiding parties across the border.
