Meta Description: Discover which South American nation holds the title for the longest coastline! This comprehensive guide explores the vast coastlines of South America, comparing lengths and highlighting the unique geographical features of each country. Uncover fascinating facts and learn about the diverse ecosystems these coastlines support.

Unveiling the Coastal Champion of South America

South America, a continent blessed with diverse landscapes, boasts an extensive coastline along both the Atlantic and Pacific Oceans. But which country reigns supreme with the longest stretch of shoreline? The answer might surprise you! While many might guess Brazil, due to its sheer size, the actual winner is... Chile.

Chile's remarkably long coastline stretches over 6,435 kilometers (4,000 miles), a figure significantly surpassing that of its South American neighbors. This impressive length is a result of the country's unique geography, extending along the Pacific coast of South America for over 4,300 km (2,700 mi). Its coastline's length is also impacted by the numerous islands and inlets along the coast of Chile.
