Ruen Peak
Ruen Peak is a high mountain pass at an elevation of 2.246m (7,368ft) above the sea level, located on the border of southwestern Bulgaria and northeastern Republic of North Macedonia. It's one of the highest roads of the country.
The road to the summit, located within the Osogovo-Belasica group, is totally unpaved. The road is usually impassable in winters. Great trail for experienced wheelers. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 required. Stay away if you're scared of heights. Expect a trail pretty steep. Wet conditions may make for tough driving along the muddy road.
