The Polish–Czech Friendship Trail (Czech: Cesta česko-polského přátelství, Polish: Droga Przyjaźni Polsko-Czeskiej) is a public walking path in the Giant Mountains. The path runs on both sides of the Czech–Polish border, along the main ridge and crosses or traverses all its summits. The maintenance of the trail is performed by the staff of both adjacent national parks: the Polish Karkonosze National Park and the Czech Krkonoše National Park. The start point is located on Szrenica and the end in the Okraj pass / Pomezní boudy; the length of the trail is approx. 30 km; the level of difficulty is moderate. The trail partially overlaps with ski trails. The trail is marked with red stripe signs. Many places at the trail are equipped with two signposts parallelly: with Polish one in Polish language according to Polish standards, with distances in hours, and with Czech one in Czech language according to Czech standards, with distances in kilometers.
