Santuario de la naturaleza Humedal Río Maipo

The Maipo River Wetland Sanctuary is a protected natural reserve combining saltwater marshes and freshwater lagoons in the Valparaíso Region. The site stretches along the river with dense vegetation, reeds, and open water areas connected by pathways and observation platforms for visitors.

The site was originally a landfill that received protected status in the early 2000s. This transformation from waste disposal area to ecological reserve represents a significant recovery of natural habitat.

The sanctuary serves as an educational center where visitors learn about wetland ecosystems through interactive outdoor exhibits and guided interpretive trails.

Access is via marked wooden boardwalks that remain walkable in wet conditions and accommodate different mobility levels. Visitors should wear weather-appropriate clothing and closed shoes since the terrain is marshy and insects are common during warm months.

The site hosts nearly 200 bird species, including rare migrants that regularly stop here during their long journeys between North and South America. This role as a resting point makes it a top destination for observers wanting to see traveling birds across different seasons.
