In the far southwest of Transylvania, Retezat National Park is a large mountain park (38 000ha), with two peaks that exceed 2 500m. It is punctuated by nearly 80 glacial lakes. Populated by chamois, deer, roe deer, wolves, bears and lynx, the park is also home to more than 1 900 plants, some of which are very rare. Many trails criss-cross the park and some "chalets" offer hikers a pleasant refuge to spend a night surrounded by nature.
