The Road to Vintcheto is a high mountain road climbing up to Kalin Reservoir, at 2.398m above the sea level, and Karagyol Reservoir, at 2.359m above the sea level, located in southwestern Bulgaria.

The road is located in the Rila mountain range. The surface is concrete (in pretty bad conditions), narrow and steep. There are sheer drops virtually along the entire route and enough hairpins to make a whirling dervish dizzy. This route is not recommended if your passengers are prone to car sickness. Vintcheto, the summit, is marked by a crumbling old building. To get there you’ll have to nearly 18km at an average gradient of nine per cent, with some parts up to 12%.
