"One of Colombia’s biggest nature reserves, Chingaza protects more than 1,000 plant species and 187 bird species and teaches about the páramo ecosystem and its role in the global water system; nearly 80% of Bogotá’s water supply comes from Chingaza’s natural lakes and reservoirs. If hiking, join a tour led by naturalist guides; a standout route is the challenging hike to the summit of Lagunas de Siecha with great views over the lakes." - Matthew Kepnes
