Cerro de la Muerte is a high mountain pass at an elevation of 3,451 m (11,322 ft) above the sea level filled with steep curves and potholes. It’s the highest point in the Costa Rican section of the Inter-American Highway, the Central American section of the Pan-American Highway.
The name of the pass means "Mountain of Death", since many travelers succumbed to the cold and rain in the past. This part of the highway has excessive potholes, steep, narrow curves, and plenty of fog.
The road is in dreadful condition, with thousands of trucks, and requires strong nerves to negotiate it. Any barriers along the edge afford little more than token protection; large stretches should be taken at a snail's pace and a lookout kept for vehicles coming from the opposite direction!
Due its climb in elevation over thousands of feet, and pass through remote areas, it is important when driving in these conditions to be prepared. This road goes through different various climates and temperatures. Check weather forecasts before leaving home, and remember that it becomes cooler and often more prone to storms at higher elevations. Be prepared with jackets, water, and emergency kit in your car.
This road is usually open all year long. But flash floods and landslides as well as narrow curves and steep cliffs make the pass extremely dangerous. Conditions can change quickly and be harsh, particularly during winter. Road closures can be frequent, so check conditions before traveling in winter!
