The "Sierra de Purial" mountain chain, near the eastern tip of Cuba, in the south of the province of Guantanamo
The Sierra de Purial Mountains at one stage separated the city of Baracoa, the first place that Christopher Columbus landed on his first trip to the Americas, from the rest of Cuba.
Before the Cuban Revolution the only access was by sea, but in the 1960s a 120 km long road from Guantanamo City, named "La Farola", was built through the mountains. This was one of the showcases of the Cuban revolution.
The road had been planned by the overthrown Batista government, but never built. The highest point of the road is at over 600 meters above sea level, and it passes over 11 bridges.
The Sierra de Purial mountain chain is 74.7 km long, and reaches an elevation of up to 901 metres above sea level.
