Kaňkovy hory, Nature reserve in Seč, Czech Republic.

Kaňkovy hory is a national nature monument covering 224 hectares of the Železné hory ridge near Třemošnice, including its highest point at 560.0 metres. The protected area preserves beech forests, talus woodlands, alder carrs and floodplain forests.

Kaňkovy hory was first protected in 1955; the current national nature monument was declared in 2016 when the former Lichnice–Kaňkovy hory reserve was split, creating Kaňkovy hory and the separate Lichnice reserve. In 1991 the area became part of the Železné hory protected landscape area, and it lies within the Natura 2000 site Lichnice–Kaňkovy hory.

The reserve protects nesting forest birds, notably the stock dove (Columba oenas) and the red-breasted flycatcher (Ficedula parva). Birdwatchers visit the beech and ravine forests to look for these species, which are the stated subject of protection.

The reserve is accessible through a well-marked trail system, with a red path following the ridge and green paths connecting nearby villages. Visitors should wear suitable footwear and bring weather-appropriate clothing, as the terrain is hilly and conditions can change quickly.

Kaňkovy hory is part of the larger Natura 2000 site Lichnice – Kaňkovy hory, and in 1991 the area was included in the newly declared Železné hory Protected Landscape Area. The national nature monument itself was declared in 2016, when the former Lichnice – Kaňkovy hory reserve was split in two, the other part becoming the Lichnice reserve.
