Ptačí Kupy

Ptačí kupy is a peak in the Jizera Mountains, rising above the village of Hejnice in the Liberec District, best known for the striking granite rock formations that crown its summit. Reaching 1,013 metres above sea level, it offers one of the more distinctive viewpoints in this part of the range and can only be reached on foot, via marked hiking trails.

What makes Ptačí kupy stand out?

The main draw is a set of rock formations shaped by frost weathering of the underlying granite bedrock. Over thousands of years, this process carved out distinctive rock towers and blocks that experts consider an exceptional geomorphological phenomenon for the Jizera Mountains. These formations, together with the surrounding forest, are protected within a nature reserve covering the summit area and the north-western slope of the mountain.

The Ptačí kupy Nature Reserve

The reserve covers 11.76 hectares and spans elevations between 900 and 1,008 metres. It protects not only the granite formations themselves but also beech forest stands that are unusually rare at this altitude in the region. The area carries double protection status — as a nature reserve and as part of a protected landscape area — and is additionally included in the European Natura 2000 network, underlining its importance for preserving the region's biodiversity.

What vegetation grows on the summit?

The summit forests are mixed. European beech (Fagus sylvatica) dominates, growing alongside Norway spruce (Picea abies) and rowan (Sorbus aucuparia). Beech stands at such elevation are uncommon in the Jizera Mountains, where conifers typically take over higher up, which adds to the ecological value of the site.

How do you get to Ptačí kupy?

The summit viewpoint can only be reached on foot, following marked tourist trails. It lies roughly 8 kilometres from the village of Hejnice and about 12 kilometres from Oldřichov v Hájích. The route passes through forest landscape typical of the Jizera Mountains, and the climb is rewarded with views of the rock towers and the surrounding mountain range.
