Postăvarul Massif, Mountain summit in the Eastern Carpathians, Romania

Schuler, also called Postăvarul, is the highest peak of the Postăvarul Massif at 1,799 metres. The massif lies at the southern end of the Eastern Carpathians and, with Piatra Mare, forms the Bârsei Mountains group above the Țara Bârsei depression. Poiana Brașov ski resort sits on its northern slopes, and a cable car runs from the resort to the summit.

The massif's German name Schuler and Hungarian name Keresztényhavas are recorded alongside the Romanian Postăvarul. It stands at the southern end of the arc of the Eastern Carpathians and, with the neighbouring Piatra Mare Massif, forms the Bârsei Mountains group above the Țara Bârsei depression. Poiana Brașov, a well-known Romanian ski resort, was laid out on its northern slopes.

The massif carries three traditional names: Postăvarul in Romanian, Schuler or Schulerberg in Transylvanian German, and Keresztényhavas in Hungarian. Poiana Brașov, one of Romania's best-known ski resorts, occupies the northern slopes, and a cable car runs from the resort up to the 1,799-metre peak.

The winter season brings multiple ski slopes of varying difficulty connected by modern cable cars and serviced with artificial snow systems for consistent conditions. In warmer months, hiking trails demand good physical preparation and appropriate gear since weather can change quickly at higher elevations.

The massif's German name, Schuler, and Hungarian name, Keresztényhavas, reflect the region's Transylvanian Saxon and Hungarian heritage. The highest point is also called Postăvarul, popularly shortened to "Postăvaru" without the final l. The massif forms the Bârsei Mountains group together with the neighboring Piatra Mare Massif.
