The Polish–Czech Friendship Trail (Czech: Cesta česko-polského přátelství, Polish: Droga Przyjaźni Polsko-Czeskiej) is a public walking path in the Karkonosze Mountains (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 trail is marked red and the signs mostly bilingual. 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.
