Český ráj Protected Landscape Area, Protected nature reserve in Královéhradecký kraj, Czech Republic.

Landschaftsschutzpark Böhmisches Paradies is a protected nature reserve in Královéhradecký region covering terrain shaped by sandstone cliffs, deep forests, and extinct volcanic formations. The area stretches between Turnov and Jičín, featuring underground lake systems and rocky outcrops throughout its boundaries.

The reserve became the first protected nature area in the Czech Republic when it was established in 1955, marking a turning point for landscape conservation in the nation. Evidence of human presence in the region reaches back millennia through archaeological findings embedded in the geology.

The name Český ráj, or Bohemian Paradise, was coined in the 19th century by visitors who came to the sandstone formations around Turnov. The area's rocks have long drawn climbers and walkers, and the village of Malá Skála hosts a stone-cutting and jewellery tradition linked to local garnets.

Marked hiking trails and cycling routes link natural features throughout the area, with visitor centers offering maps and guidance at key locations. Paths suit different fitness levels and allow for visits ranging from short walks to full-day explorations.

The Bozkov dolomite caves, managed by the Český ráj administration though lying outside the protected area, are closed to the public in parts to protect the lesser horseshoe bat. The same bat protection keeps the carved sandstone adit at the foot of Kozákov shut. Kozákov itself, at 745 m the highest point of the area, is a known find site for precious stones, especially quartz varieties.
