The Bucegi Mountains are part of the Southern Carpathians, and are located in central Romania, south of the city of Brașov. They are bordered by the Prahova Valley to the east, the Ialomița Valley to the west, and the Rucăr-Bran Corridor, a mountain pass connecting the Romanian provinces of Transylvania and Muntenia, to the south. The Bucegi is believed to be the Dacian holy mountain Kogainon, on which the God Zalmoxis resided in a cave. The Bucegi Mountains are a popular destination for hiking, climbing, ski touring, and other outdoor activities. The easiest route to the top is from Bușteni, on the western side of the mountains.

The Piatra Craiului Mountains are a mountain range in the Southern Carpathians in Romania. In Romanian "Piatra Craiului" means "Prince's Stone".

The ridge is regarded as one of the most beautiful sites in the Carpathians.
