Route 999 is an east-west regional route in the northern Golan Heights, which Israel captured from Syria in the Six-Day War in 1967. For almost its entire length its access is restricted to Israeli army vehicles. It begins from Sion (Hebrew: שיאון, pronounced see-OWN) adjacent to the community Snir and the village Ghajar, where it splits north from Highway 99. About 2 km after this junction stands an IDF checkpoint. After the checkpoint the road moves in a northeast direction and climbs steeply on Shebaa farms in parallel with the international border between Golan Heights and Lebanon (the Blue Line). The road passes near the Shebaa farms while it passes on its steep course in the Mount Hermon nature reserve. For the entire length of the road, IDF installations are standing, and it ends its length of 29 km with another IDF checkpoint near the lower cable-car of Mount Hermon, where it meets Highway 98.
