Rocas Atoll, Volcanic atoll in Rio Grande do Norte, Brazil.
Rocas Atoll is a coral formation in Rio Grande do Norte comprising two main islands, Cemitério and Farol Cay. The structure was built by coral growth and encloses a large lagoon that creates a rich marine environment.
The Brazilian Navy built the first lighthouse on Farol Cay in 1933 to aid navigation in the region. The structure was modernized and expanded during the 1960s.
The site serves as a marine conservation area where research and species protection take priority over casual visitation. Locals and researchers view it as a symbol of Brazil's commitment to preserving ocean ecosystems.
Access requires special permits, and transportation is arranged by boat from Natal on the mainland. Visitors should be prepared for variable sea conditions and limited availability of departure dates.
The lagoon shelters an unusual mix of marine life including nesting sea turtles, sharks, dolphins, and migratory birds all occupying the same waters. This combination of species makes it a valuable site for understanding how different ocean creatures coexist.
