Cerro Negro means 'Black Hill', and it is the perfect description of this truly unique volcano. The Cerro Negro volcano was formed less than 160 years ago (in 1850) and that makes it the youngest volcano of Central America. The volcano's young age and constant volcanic activity have made it impossible for trees and plants to grow on the steep, black slopes. Some slopes are covered by huge volcanic rocks, others by fine volcanic sand.
Ascending the volcano is relatively easy. There is a basic trail composed of rearranged volcanic rocks. A bit unconfortable at times, and coupled with the intense sun without any shade this makes for a short but possibly tough climb. One can be at the top within 40 minutes. Once at the top, you can walk around the crater rim and enjoy a superb view. You can observe the impressive crater as well. Going down is a lot easier, as you can run down the sandy slope and be at the bottom within 10 minutes. This slope is also used to sand-ski.
