Larreynaga (pronounced as /es/) is the second largest municipality in the León Department of Nicaragua. The municipality seat is the town of Malpaisillo.[2] The estimated population of the municipality is 33,117 but it is steadily growing at a rate of 2.22% yearly.[3]
The municipality of Larreynaga was founded by Colonel Manuel Ignacio Pereira Quintana on August 11, 1944. The town of Malpaisillo was officially declared a city in September 1968. It got its name "Larreynaga" from Miguel Larreynaga, a Nicaraguan philosopher, humanist, lawyer and poet.[3] [4]
The municipality of Larreynaga is home to the Cerro Negro volcano, just 10 km from the city of Malpaisillo. Cerro Negro has erupted frequently since its first eruption.[5] The last volcanic activity at Cerro Negro occurred on August 5, 1999, and lasted for a total of two days.
In recent years, the Cerro Negro volcano has been a popular destination for sandboarding.[6]
