Páramo de Sonsón, Nature reserve in Sonsón, Colombia.

The Páramo de Sonsón is a highland nature reserve in the Cordillera Central of Colombia, within the municipality of Sonsón, Antioquia, reaching 3350 m at its highest point. It borders the municipalities of Argelia and Nariño and the department of Caldas. Rivers and streams rise here and drain toward the Magdalena River.

The Páramo de Sonsón lies in the Cordillera Central, the Andean range that crosses Antioquia, and its streams drain toward the Magdalena River. Environmental authorities study its conservation and have implemented national programmes there, among them the "familias guardabosques" scheme, which pays local families to keep watch over forest and moorland.

The reserve is the setting of the national "familias guardabosques" programme, in which local families take part in conservation work. It also forms part of an ecological corridor linking the Parque Natural de los Nevados, the Selva de Florencia in Samaná (Caldas), the wetlands of the Magdalena Medio, the Laguna de San Diego and the Cañón de Río Claro.

Visitors should prepare for cold, wet conditions by wearing warm, waterproof clothing and sturdy hiking boots. The terrain is often muddy and slippery, so having proper gear makes walking safer and more comfortable.
