Estero El Yali is a natural watercourse that originates in the Metropolitan Region and flows through the Valparaíso Region, specifically the commune of Santo Domingo. The water body is a central feature of the Reserva Nacional "El Yali," a protected area located in Santo Domingo, San Antonio Province. This setting makes it a significant site for birdlife, including nesting and protection areas for species such as the coscoroba swan, black-necked swan, Chilean flamingo, and various gulls. For paddlers, this translates into a wildlife-focused experience where observing these birds from the water is a key attraction. The overall character is defined by its ecological importance within a national reserve. Access points, boat ramps, and facilities for a day on the water are available. No information is available regarding recommended routes, seasonal water temperatures, water quality, specific hazards, paddling restrictions, or the best times for paddling. The aesthetic is tied to its wetland environment within the reserve, and its geographical characteristic is that of a flowing estero, or stream, through this protected coastal area.
