Tresna is a small, yet quite popular Polish mountain resort with many ski slopes and hiking trails in the vicinity. It is considered as a paradise for water sport enthusiasts since it lies by Zywieckie Lake and with access to outdoor pools. Unfortunately, its accommodation offer is not very diversified. Since there are just a few hotels in the area, booking something at short notice can be problematic. That is why we strongly advise you to book your accommodation in advance.
