Slănic (occasionally Slănic Prahova) is a town in Muntenia.
Slanic is reached by a railway, but trains can't actually enter the town because of a damaged bridge; instead they stop about 10 km away in Poiana Slănic (which is linked with Slănic itself by minibus) . There are three or four commuter trains daily from Ploieşti (50 minutes travel time); timetables are available on the rail operator CFR website  [dead link].
The town can be visited on foot.
