Rosario and San Bernardo Corals National Natural Park

Rosario and San Bernardo Corals National Natural Park is a Colombian marine protected area off the Caribbean coast in Bolívar Department that conserves coral reefs, small islands and associated marine habitats.

The park encompasses reef systems and island environments that are used for recreational snorkeling, diving and coastal visits, and it serves conservation and research purposes to protect marine biodiversity. Tour operators commonly run day trips from Cartagena and nearby coastal towns to beaches and reef sites within the park.

The protected area was established by the Colombian government to safeguard coral reef ecosystems and island habitats threatened by development and fishing pressure, and management focuses on balancing visitor access with conservation.

Geographically the park is located off the northern Colombian Caribbean coast near Cartagena in Bolívar Department and includes an archipelago of small islands and surrounding reef waters.

• Main attractions: The park protects coral reefs, mangroves and small islands that are popular for snorkeling, diving and day-trip beach visits from Cartagena.

Access is by boat from Cartagena or nearby coastal towns; many visitors join organized day tours or diving trips that include transport and park permits.

• If diving the corals, use operators accredited for reef-conservation practices and avoid anchoring on reefs.
• Plan visits outside the peak rainy seasons for better underwater visibility.
• Bring a reef-safe sunscreen and follow local guidance to protect coral habitats.
