Karkonoszka Pass is a mountain pass located in the central Karkonosze Mountains on the Polish-Czech border situated in Dolnoslaskie, at an elevation of 1.198m (3,930ft) above the sea level.
The road to reach the summit is known to be the steepest road of Poland with 28% in places, with an average of 15% on 820m of ascent. The reason of this is that they once planned a road for cars, with laces like the Czech one, and built a preliminary road for engines. For some reason the project was never achieved, and only the engine road remained. Since then cyclers regularly challenge on it, and there is even a yearly race.
Starting from Podgórzyn, the ascent is 10.2 km long with an elevation gain of 827 meters. The average percentage is 8.1 %. Located within the Karkonoski National Park, the pass is accessible by a road either from Špindlerův Mlýn, served by bus, or from Poland. The Polish road is said to be one the steepest roads in Poland with the average inclination 7.2%, reaching 24% at maximum. The surface of the road is asphalted, and chains or snow tyres can be required anytime. Although road quality on the Polish side is relatively poor, the pass is much sought after by mountain bikers. The pass is a hub of hiking trails, including the Polish-Czech Friendship Trail.
