Przejscie Kotliny Jeleniogórskiej can be translated as "Passage of the Jeleniogórska Valley".

Helags can have very harsh weather and there is no protection on the summit. You will travel in some areas with no people and no trails. Loose rocky and technical terrain and some ridges can feel airy. I would only recommend this adventure for experienced runners.
