San Bernardo Archipelago

The San Bernardo Archipelago (Archipiélago de San Bernardo) is a group of 10 coastal islands in the Gulf of Morrosquillo, also part of the Caribbean Sea. These islands, covering an approximate area of 213 sq km (82 sq mi), fall under the jurisdiction of the Bolívar Department. The San Bernardo Archipelago is known for its ecological significance and is less developed compared to the Rosario Islands, offering a more secluded and serene experience.

The San Bernardo Archipelago includes the following islands:

• Boquerón Island (Isla Boquerón)
• Palma Island (Isla Palma)
• Panda Island (Isla Panda)
• Mangle Island (Isla Mangle)

• Santa Cruz del Islote (Holy Cross Islet)

Notable Islands

• Santa Cruz del Islote: This artificial islet is known for its high population density, estimated at around 1,200 people living on a mere 0.012 sq km (0.0046 sq mi). The islet was constructed by locals using coral and other materials, beginning around 1870. Due to its limited space, some inhabitants have moved to nearby islands such as Tintipán and Múcura.
• Tintipán and Múcura Islands: These islands are known for their natural beauty, with sandy beaches and clear waters ideal for swimming, snorkeling, and relaxation. Tintipán, in particular, is celebrated for its bioluminescent plankton, which lights up the waters at night, offering a magical experience to visitors.

Rosario and San Bernardo Corals National Natural Park

The Rosario and San Bernardo Corals National Natural Park was established in 1988 to protect one of the most vital coral reef systems along Colombia's Caribbean coast. The park covers an area of 120,000 sq km (46,300 sq mi) and covers both the Rosario and San Bernardo archipelagos and the surrounding marine environment.

Ecological Importance

The park safeguards diverse marine habitats, including coral reefs, mangrove swamps, and seagrass meadows. These ecosystems are home to hundreds of marine species, such as fish, mollusks, crustaceans, and various types of coral. The park's coral reefs are particularly notable for their extent and biodiversity, representing some of the most developed coral formations along the continental shelf of the Colombian Caribbean.

Conservation Efforts

Within the park, four islands are designated as untouchable zones to preserve their natural state: two in the Rosario Archipelago (Tesoro and Rosario Islands) and two in the San Bernardo Archipelago (Maravilla and Mangle Islands). These protected areas help maintain the ecological balance and support conservation research and educational initiatives.

Climate and Environment

The Rosario and San Bernardo Islands experience a tropical maritime climate characterized by warm temperatures throughout the year, with an average annual temperature of about 27°C (81°F). The region sees distinct wet and dry seasons, with the rainy season occurring from May to November, bringing increased humidity and occasional tropical storms.

Tourism and Accessibility

These islands are accessible by boat from Cartagena, making them popular for day trips and extended stays. Tourists flock to the islands to enjoy the natural beauty, engage in water sports, and explore the vibrant marine life. Several islands have accommodations ranging from luxury resorts to more rustic lodges, catering to various preferences and budgets. Coral reefs, shipwrecks, and underwater caves make the Rosario and San Bernardo Islands a premier destination for diving enthusiasts.

Cultural and Historical Significance

Apart from their natural beauty, the islands hold cultural importance due to their historical connection to Indigenous communities and their role in Colombia's maritime history. Efforts to preserve the natural environment are complemented by initiatives to maintain the cultural heritage of the local communities, ensuring that both natural and cultural landscapes are respected and protected.

Conclusion

The Rosario and San Bernardo Islands, along with the Rosario and San Bernardo Corals National Natural Park, represent a crucial area for marine biodiversity conservation and a popular destination for ecotourism in Colombia. The combination of pristine beaches, diverse ecosystems, and rich cultural history makes this region a unique and valuable part of Colombia's natural heritage. Continued efforts in conservation and sustainable tourism practices are essential to preserve these natural wonders for future generations.
