Playa Changa is a coastal beach located within the bustling port city of Coquimbo in Chile's Coquimbo Region. This beach forms part of the greater La Serena-Coquimbo urban area and is situated within the broader Bahía de Coquimbo. The shoreline is characterized by its tranquil, clear waters and is adjacent to the important "El Culebrón" wetland ecosystem. The beach itself is a site of significant ancestral and ongoing cultural activity, primarily focused on the sustainable harvesting of seaweed, known locally as "oro negro" or "pelillo." The intertidal and nearshore environment supports a diverse marine community, including various algae and invertebrates, which in turn creates a productive habitat for fish. Anglers visiting this urban beach should be prepared for a mix of natural beauty and the practicalities of fishing near a major port, including areas with accumulated seaweed and potential litter.
