Geography
The Chocó biogeographic region runs from the Darién Gap in the north to southern Ecuador, squeezed between the Pacific Ocean and the western flank of the Western Andes. Colombia holds most of its north-central section. Rainfall exceeds 10,000 mm per year in some areas, making it the wettest lowland forest on the planet.
Why birders come here
Sixty-plus species are restricted to the Chocó, and many are found nowhere else in Colombia. Cerro Montezuma, on the western flank of the Serranía de Tatamá, is the single best site for Gold-ringed Tanager, Munchique Wood-wren, and Black-and-gold Tanager. Anchicayá Valley, reached from Cali, is the most accessible transect from Andean foothill to Pacific lowland.
Best access
Cali is the standard gateway. From Cali, Km 18 and Anchicayá are half-day and full-day accessible. Cerro Montezuma requires a dedicated multi-day visit and 4x4 transport to the summit ridge before dawn.
Logistics
- Main gateway: Alfonso Bonilla Aragón International (CLO), Cali
- Secondary access: Matecaña International (PEI), Pereira, for Tatamá / Otún
- Weather: hot humid at sea level; cool and very wet in cloud forest above 1,800m
- Difficulty: trails are muddy year-round; waterproof boots essential
Conservation context
The Chocó is under pressure from deforestation for palm oil, mining, and infrastructure. Partner reserves (Tatamá area, Los Tangaras near Mistrató) depend on eco-tourism revenue. Responsible birding operators contribute directly to keeping this forest standing.
