These are the highest mountains of the Southern Carpathians, in Romania.
They are bordered in the north by the Făgăraș Depression, through which the Olt river flows, and in the west by the Olt Valley (Valea Oltului).
A road called the Transfăgărășan runs across the Făgăraș Mountains.
It is generally open only between June and September, due to unfavorable weather conditions in the rest of the year.
