The vicinity of mountain Kosmaj (13 km) offers enjoyment in the increasingly popular excursion and hunting tourism. The recognizable symbol of this mountain and the entire region is a large monument erected on its top in 1971, in memory of the soldiers of the partisan unit formed in Kosmaj, who were killed in World War II. Spa tourism is already well developed. Selters Spa, famous for its thermomineral water, which was discovered in 1898, has enjoyed good reputation in the whole world for a long time.
Angling is possible on two lakes near Mladenovac – Rabrovacko and Markovacko lakes. The latter also has catering and accommodation facilities.
Almost all sacral buildings constructed at the end of the 14th and the beginning of the 15th century testify to the omnipresence of despot Stefan Lazarevic (1377-1427) in the territory of the present-day municipality of Mladenovac. He was a son and heir of the holy Serbian prince Lazar Hrebeljanovic, one of the greatest Serbian rulers, and his wife princess Milica. Tresije Monastery in Kosmaj, which was built by King Dragutin at the end of 13th and the beginning of 14th century, was extended and reconstructed by despot Stefan one century later. He also built Pavlovac Monastery. These monasteries, together with the already existing monasteries of Kastaljan and Velika Ivanca, put the mountain top of Kosmaj under the protection of the Holy Cross. Kosmaj was the very place where Stefan Lazarevic met his end on July 19 1427, and his companion Djuradj Zubrovic put a stone obelisk in the place of his death in Crkvine (today in this place there is a church dedicated to St Elias, which was contructed in 1884). It has been preserved to the present day and in 1979 it was put under protection as a cultural monument of outstanding importance to the state.
