Do You Know? The Longest Beach in the World Is in Brazil

Praia do Cassino in southern Brazil is widely cited as the longest beach in the world, extending for about 254 kilometers along the Atlantic coast of Rio Grande do Sul.

However, the record depends on how a beach is measured. Praia do Cassino is often described as the longest continuous sandy beach, while Cox’s Bazar in Bangladesh is commonly recognized as the longest unbroken natural sea beach.

Where Praia Do Cassino Is Located

Praia do Cassino lies in the municipality of Rio Grande, near Brazil’s border with Uruguay. The main resort area is around 22 kilometers from central Rio Grande and about 334 kilometers from Porto Alegre by road.

According to the ⁠Rio Grande municipal tourism authority, the coastline stretches for approximately 254 kilometers and forms one of South America’s longest continuous beaches.

The beach is known locally as Praia do Cassino, or Cassino Beach. Its enormous scale becomes clearer away from the developed resort area, where the sand continues toward remote dunes, wetlands, and coastal landscapes.

Why The Record Is Complicated

“Longest,” “largest,” and “biggest beach in the world” do not always describe the same record.

Praia do Cassino’s claim is based on its exceptionally long, continuous sandy coastline. Some measurements include connected coastal sections extending south toward the Uruguayan border, which can affect the total distance.

Cox’s Bazar in Bangladesh is usually described more specifically as the world’s longest natural unbroken sandy sea beach. Official Bangladesh tourism sources give its length as roughly 120 kilometers.

The fairest comparison is:

  • Praia do Cassino: Widely cited as the longest continuous sandy beach
  • Cox’s Bazar: Widely cited as the longest unbroken natural sea beach

Different definitions allow both claims to appear in travel and geographic references.

Visiting Cassino Beach

Cassino Beach is more than a geographic record. Visitors can walk along the shore, watch migratory birds, explore protected dunes, surf during suitable conditions, and visit the Molhes da Barra breakwaters.

One unusual feature is that vehicles are permitted on sections of the beach. Drivers should follow local restrictions and take extra care around soft sand, changing tides, wildlife, and other visitors.

The resort area has hotels, restaurants, shops, and seasonal services. Summer draws the largest crowds, while quieter periods better reveal the extraordinary scale of the coastline.

Travelers planning a wider trip can explore other ⁠famous landmarks in Latin America or compare Brazil with the ⁠most visited countries in South America.
