The Transfagarasan is a scenic mountain road in Romania that stretches for about 90 miles between the cities of Campulung and Curtea de Arges. It was built during the Communist regime in the 1970s and was initially intended to serve as a military route that would provide access to the Fagaras Mountains in the event of a Soviet invasion. However, its stunning views and breathtaking scenery soon made it a popular tourist destination.

The road features hairpin turns, steep inclines and drops, and breathtaking views of the Fagaras Mountains. It also crosses two high mountain passes, the Balea Lake and the Vidraru Dam, both of which offer stunning views of the surrounding landscape.

The Transfagarasan is considered to be one of the most beautiful and challenging roads in the world, and it attracts thousands of tourists every year who come to drive or cycle its length, or simply enjoy the views from one of its many viewpoints. In addition, the road is also popular among adventurers and thrill-seekers, who come to test their skills and take on the challenging mountain terrain.
