Monumento Natural La Portada is a stunning geological arch situated in Antofagasta, Chile. This natural marvel is an essential stop for anyone exploring the area. Standing at 42 meters tall and 23 meters wide, the arch exemplifies the incredible effects of wind and sea erosion over millions of years.
La Portada was once submerged beneath the ocean over 30 million years ago. The sedimentary rocks and fossilized shells formed during this era have been sculpted by the persistent forces of wind and sea, resulting in the iconic arch we admire today. It was designated as a Natural Monument in 1990, becoming a protected site and a symbol of the region’s geological heritage.
To visit La Portada, travelers should head north from Antofagasta, approximately 20 kilometers away. The site can be accessed via the highway that connects Antofagasta and Tocopilla. Alternatively, visitors can take a short lateral road west off the highway, leading to a small museum managed by Conaf and offering cliff-top views of the nearby beaches.
Entry to La Portada is free, making it an accessible and budget-friendly attraction for travelers.
La Portada is a natural gem that highlights the region’s distinctive geological history and promises an unforgettable experience for all visitors.
