It is best to choose the direction from Święty Krzyż towards Łysica. You can then fully enjoy the technical downhill rides. I am begging you, do not go there with gravel bikes because there will be some tragedy! : D
The uphill route on Jeleniowskie Ścieżki. Some fitness required: there are steep moments and a few serpentines. A forest path through beautiful, dense forests. Great. You have 183m up in a little over 2km.
Great downhill trail after the end of the "Strumyk" route. Beautiful ride through the forest, plus rock gardens, stones, bridges, drops. Almost 2 kilometers of riding and 176 meters of elevation. Not difficult, but not for complete beginners.
