Laguna Verde de Azufral: Driving the restricted emerald crater road of Colombia

Laguna Verde de Azufral is a stunning emerald-green volcanic lake sitting at an elevation of 3,970m (13,025ft) above sea level in the Nariño department of southern Colombia. Located within the Azufral Natural Reserve, the track leading to this dormant volcano's crater is one of the most beautiful yet challenging drives in the region.

How long is the road to Laguna Verde?

The route, historically known as the Via acceso Laguna Verde, starts from Carretera 17 near Villa Santa Isabel. The road is 11.7 km long with a steady elevation gain of 770 meters. It is a totally unpaved, steep, and narrow track that worsens progressively as it climbs toward the north side of the Volcán Azufral.

What were the driving conditions like?

Before the closure, the road had a well-deserved reputation for being dangerous. It required high-clearance 4x4 vehicles to navigate the deep ruts and sharp gradients. At the end of the trail, a winding section led to a panoramic viewpoint at 4,000m, offering a breathtaking view of the three lagoons within the crater. The weather here is notoriously unpredictable, with sudden snowstorms, fierce winds, and dramatic temperature drops being common year-round.

Why is the Azufral volcano road closed?

The decision to close the road to the Laguna Verde was made to protect the unique biodiversity and the striking emerald color of the water, which was being affected by human impact. Today, the area is under strict environmental protection. While the road remains a legendary part of Colombian 4x4 history, it now serves as a reminder of the need to preserve these high-altitude volcanic landscapes.

Tips for travelers in the Nariño region

Although you can no longer drive to the crater, the surrounding Nariño department offers incredible mountain scenery. If you are exploring the area near Villa Santa Isabel, always carry waterproof gear and warm clothing, as the high-altitude climate remains fierce. Respecting the "No Entry" signs of the Reserva Natural del Azufral is mandatory for all visitors.
