Cerro Negro Volcano is an active volcano located in Nicaragua, near the city of León. It is one of the youngest volcanoes in Central America, having first erupted in 1850. Cerro Negro is unique among volcanoes as it is primarily composed of loose ash and cinders, which can be easily eroded and redeposited by wind and rain. This has created a constantly changing landscape of black sand and ash slopes.

Cerro Negro is one of the most active volcanoes in Nicaragua, having erupted over 20 times since its first eruption in 1850. Despite its frequent eruptions, it has not caused significant damage to the surrounding area, as its eruptions are typically small and explosive.

Despite the danger posed by an active volcano, Cerro Negro has become a popular tourist destination, offering visitors the opportunity to hike to the summit and view the crater. The hike to the summit is relatively easy and takes about an hour, although the climb to the top can be strenuous. From the summit, visitors are rewarded with breathtaking views of the surrounding countryside, as well as the opportunity to watch the steam and ash clouds produced by the volcano's ongoing activity.
