Predeal is well connected by train. CFR Călători operates regular services on the Bucharest–Brașov main line, and the journey from Bucharest's Gara de Nord takes around two hours; from Brașov it is about 30 minutes. Trains stop at the small Predeal station in the centre of the town.
By road, the DN1 (E60) national highway passes straight through town. The drive from Brașov is around 30 km; from Bucharest approximately 160 km, with the mountain section of the road prone to winter closures and heavy weekend traffic in ski season.
