The Olt Defile (Romanian: Defileul Oltului) is a defile that has been cut into the Transyvanian Alps in south-central Romania by the river Olt. In the Brezoi–Titești Depression portion of the defile there are located hot spring resorts. In the surrounding mountains grow walnut and oak trees, wild roses, and white ivy. Transportation is provided by highways and railways between Râmnicu Vâlcea and Sibiu.[1]
