Lots of turist go from Świeradów Zdrój by Gondola up the hill to Stóg Izerski. They look around and go back. But there are so grate possibilities. One of them it take an advantage of cross country skiining paths. The terrain on the top is very gentle and suitable also for beginners. We took cross-country skiing path from Stóg Izerski through Polana Izerska to Chata Górzystów and back down to Świeradów Zdrój, together 19 km in 6 hours with 8 years old. Definitely to recommend, specially that you can take a rest in Chta Górzystów in the great atmosphere by fireplace and delicious food.
