The canyon is home to one of the largest colonies of Griffon vultures in Europe.
The name 'Garganta Verde' refers to the intense green moss and lichen that grow on the damp limestone walls.
The route passes the 'Ermita,' a cavern so large it mimics the interior of a cathedral.
The canyon is part of a UNESCO Biosphere Reserve designated to protect the pinsapo (Spanish fir).
Geologically, the gorge is a canyon-type karstic depression created by the hydraulic force of the Pinar stream.
La Garganta Verde is a profound canyon carved by the Arroyo del Pinar within the Sierra de Grazalema Natural Park. The limestone gorge reaches depths of up to 400 meters, featuring vertical walls and hidden subterranean passages. The route includes the Ermita de la Garganta, a large cave naturally formed within the canyon floor that displays significant stalactite and stalagmite formations. Access to the canyon is strictly regulated by the regional environmental authority due to its ecological status as a protected vulture nesting site. The canyon is a high-level destination for technical canyoneering, requiring specialized equipment and experienced navigation skills. The landscape is characterized by Mediterranean scrub and holm oak forests surrounding the karst relief. Geology enthusiasts note the canyon as a primary example of fluvial erosion cutting through Jurassic limestone.

Permits from the Sierra de Grazalema Natural Park visitor center are mandatory to enter the canyon.
Water levels can rise rapidly during rainfall, making the canyon dangerous to traverse during wet weather.
Carry at least two liters of water, as there are no replenishing stations once inside the gorge.
Attempting the canyon without a professional guide or specialized technical gear, as the terrain is rugged and involves rappelling.
Access is restricted or prohibited during the vulture nesting season, typically from July through September, though exact dates fluctuate annually based on bird behavior.
Strict adherence to 'Leave No Trace' principles is required; do not disturb nesting wildlife or collect geological samples.
