Karpiak, Mountain peak in Lower Silesia, Poland.

Karpiak is a 782 m summit in the eastern Złote Mountains, within Śnieżnicki Landscape Park, about 3.5 km southeast of Lądek-Zdrój. Its rounded, partly rocky ridge rises between the Biała Lądecka valley and Karpowska Pass. The top is a nearly flat clearing of grasses and ferns, built of gierałtów gneiss, with ruins of Karpień Castle.

Karpiak's summit holds the ruins of Karpień Castle, first recorded as captured and burned by the Hussites in 1428 during the Hussite Wars. Until 1513 it remained a seat of robber knights, then was destroyed for good and left in ruins. The castle guarded the nearby Karpowska Pass, crossed by the old Prague-to-Kraków salt route. In 1885 a wooden viewing tower was built within the walls, dismantled in 1899–1900.

The ruins on the summit are those of Karpień Castle, which guarded the old Salt Road trade route from Prague to Kraków through the nearby Karpowska Pass. In 1885 a wooden viewing tower was built within the castle walls and dismantled in 1899–1900. During excavations Karl Wehse had a stone bench made, carved with the inscription LOUIS SCHADOW PLATZ and the initials RA, still visible today.

The trails are clearly marked and lead from nearby towns toward the mountain. Starting early in the morning allows hikers to complete the full climb and descent during daylight hours.

The ruins on the flat summit belong to Karpień Castle, burned by the Hussites in 1428 and finally destroyed in 1513. Lime-rich mortar washed from its walls lets calcicole plants grow here, including the fern Asplenium robertianum and the snail Monachoides incarnatus.
