The water in the pool originates from the melting snow of the Sierra de Gredos peaks.
The distinct green hue of the water is caused by the depth of the natural basin and the reflection of surrounding pines.
The pool is formed by the erosion of granite bedrock, which is the dominant geological feature of this sector of the Gredos range.
The location is situated at an elevation of approximately 760 meters above sea level.
Charco Verde is a natural rock-formed swimming pool located within the Sierra de Gredos mountain range. It is fed by the crystalline waters of the Pelayo River, which flows down from the higher mountain peaks. The site is characterized by its deep, emerald-colored water surrounded by granite boulders and dense pine forests. The pool provides a cold-water bathing area that stays temperate even during peak summer months. Access involves a walk through the forest along the riverbank from the local trailhead. The area is part of the broader landscape of the Tiétar Valley, known for its rugged geography and glacial-origin formations.
The elevated rock outcrops overlooking the pool provide the best vantage point for capturing the emerald water contrast against the granite.
Bring water shoes to navigate the slippery and uneven granite rocks surrounding the pool.
The water is extremely cold; prioritize sun exposure on the rocks after a quick swim.
Carry out all trash, as this is a protected natural area with no onsite waste disposal services.
Attempting to jump from high granite cliffs into the water, as submerged boulders pose a significant risk of injury.
High water levels in spring may restrict safe swimming; the site is most accessible and safe for swimming during summer months.
Maintain silence to respect the natural wildlife; do not use soap or detergents in the water.
