Southern Carpathians (also known as the Transylvanian Alps) are the southern part of the Carpathians and are entirely located in Romania. They are the second highest part of the Carpathians (after the Tatras) and contain 3 of the 5 Carpathian ultras. They are surrounded by other Carpathian ranges to the west, north, and east, and descend into the Lower Danube (also known as the Wallachian) plain to the south. The highest peak is Moldoveanu (2544 m) in the Făgăraș Mountains, but the slightly lower Parângul Mare (2519 m) is more prominent. The third ultra-prominent peak is Peleaga (2509 m) in the Retezat Mountains.
