Mount Stogu, Protected mountainous area in Băile Olănești, Romania

Mount Stogu is a protected mountainous area near Băile Olănești featuring steep slopes covered entirely with forests. The woodland consists primarily of European beech, oak, and spruce trees that blanket the terrain.

Mount Stogu was declared a nature reserve by Law No. 5 of 6 March 2000, covering 10 hectares in Băile Olănești, Vâlcea County. The reserve lies within the Buila-Vânturarița National Park and overlaps the Cozia-Buila-Vânturarița site of community importance. Its protection targets the limestone relief and the flora and fauna of the Southern Carpathians.

The reserve lies in the Căpățânii Mountains between the Cheia and Olănești rivers, and the surrounding villages hold historic wooden and stone churches. The wooden Church of Saint Pantelimon in Băile Olănești, built in 1752, was moved there in 1907 from Albac in Alba County. The Iezer hermitage in Cheia dates from the 16th century.

Access follows DN64A from Râmnicu Vâlcea through Vlădești and Vlăduceni to Valea Cheii, then DJ654 to Cheia, where a forest road continues upstream along the Cheia River. The reserve lies between the Cheia and Olănești rivers, northwest of Cheia village, at 1,200–1,494 m. It is included in Buila-Vânturarița National Park.

The reserve is home to rare plant species including lady's slipper orchids and unusual mountain flowers that few visitors notice. The presence of large predators such as bears and lynx in these forests adds another layer to its ecological importance.
