Országos Kéktúra 13. szakasz: Piliscsaba – Nagy-Szénás – Hűvösvölgy

Section 13 of the Országos Kéktúra — Hungary's national blue trail — running from Piliscsaba railway station south through Nagy-Szénás and on to Hűvösvölgy on the western edge of Budapest. The Nagy-Szénás stretch is the highlight, with limestone grassland and open viewpoints across the southern Pilis. Trains serve both ends, so it works as a one-way day for fit hikers.
