Fodor's Expert Review Gyermekvasút
The 12-km (7-mile) Children's Railway—so called because it's operated primarily by children—runs from Széchenyi-hegy to Hűvösvölgy. The sweeping views make the trip well worthwhile for children and adults alike. Departures are from Széchenyi-hegy. To get to Széchenyi-hegy, take Tram 56 or 61 from Széll Kálmán tér, and change to the cog railway (public transport tickets valid) at the Városmajor stop. Take the cog railway uphill to the last stop and then walk a few hundred yards down a short, partly forested road to the left, in the direction most others will be going. The railway terminates at Hűvösvölgy, where you can walk downhill for a few minutes and catch Tram 56 or 61 back to Széll Kálmán tér.Various stops along the railway also act as embarkation points for hikers into the Buda Hills.
