Valyavishki Chukar, Mountain peak in Pirin National Park, Bulgaria

Valyavishki Chukar is a 2,664-meter peak in the Pirin mountain range of southwestern Bulgaria. The summit sits at the junction of three deep cirques and connects to a network of marked hiking paths in the area.

The peak was sculpted by glacial erosion during ancient ice ages, which carved out the three surrounding cirques. This geological formation has made it a recognized landmark for mountaineers over many generations.

The name is Bulgarian: chukar is the local word for a rocky peak, and Valyavishki ties it to the Valyavishki cirque and the Valyavishki Lakes below its northern slopes. The neighbouring saddle is called Mozgovishka Porta, also known as Vinarska Porta, and carries the main trail between the Demyanitsa refuge and Tevno Lake.

The climb from the nearest mountain shelter takes around 20 minutes on well-marked paths through the high terrain. The best climbing window is from June through September, when snow and ice create fewer obstacles.

The two rock edges on the northern slope are covered with large granite blocks and patches of dwarf mountain pine (Pinus mugo). One edge marks the eastern limit of the Prevalski cirque; the other ends at the shore of the largest Valyavishki Lake. Seen from Tevno Lake, the summit and its lower unnamed neighbour form a sharp, separate massif.
