The park contains the most extensive coral reef system in the Colombian Caribbean.
It is home to the Oceanario, a research and conservation facility focused on marine life education.
The park's creation in 1977 was specifically designed to protect the massive coral platforms from overfishing and environmental degradation.
The seafloor elevation varies significantly, creating distinct micro-habitats for different marine organisms.
Mangroves within the park act as natural nurseries for juvenile reef fish before they move into deeper waters.
The park's protected zones strictly prohibit motorized water sports in core reef areas to prevent coral damage.
Parque Nacional Natural Corales del Rosario y San Bernardo is an underwater and coastal protected area located approximately 45 kilometers southwest of Cartagena. It protects one of the most productive and diverse coral reef ecosystems in the Colombian Caribbean. The park encompasses 120,000 hectares of marine and terrestrial territory, including a cluster of 27 islands. Its seafloor is dominated by extensive coral formations, seagrass meadows, and mangrove forests. The area serves as a critical habitat for over 1,000 species of marine animals, including sea turtles, dolphins, and diverse reef fish. Access is primarily facilitated through maritime transport from the Cartagena harbor. It serves as a vital biological corridor for migratory species and local marine populations. The park is managed by Parques Nacionales Naturales de Colombia to ensure the conservation of its fragile coral structures.

Bring high-quality, reef-safe sunscreen to prevent chemical damage to the delicate coral ecosystems.
Carry your own snorkel gear if you want to avoid rental equipment of varying quality.
Visit during the weekday to avoid the peak crowds that arrive from Cartagena on weekends.
Avoid booking all-inclusive day tours that spend more time on transit than in the water; do not purchase jewelry or souvenirs made from coral or tortoiseshell.
Do not touch, step on, or break coral structures; apply sunscreen at least 20 minutes before entering the water; use only bio-degradable products.
