San Bernardo Archipelago

The San Bernardo Archipelago (Archipiélago de San Bernardo, Islas de San Bernardo) is a group of 10 coastal islands located in the Gulf of Morrosquillo, within the Caribbean Sea. Their approximate area is ​​213 sq km (82 sq mi). Administratively, the archipelago belongs to the Bolivar Department.

There are 10 islands in the San Bernardo archipelago but the three that receive the most tourism are Mucura, Santa Cruz and Tintipan.

The archipelago consists of the following islands:

  • Boquerón
  • Palma
  • Panda
  • Mangle
  • Ceycén
  • Cabruna
  • Tintipán
  • Maravilla
  • Múcura

Santa Cruz del Islote

Also included is the artificial islet of Santa Cruz del Islote. Since 1996, part of the archipelago belongs to the Corales del Rosario and San Bernardo Islands National Natural Park.

Santa Cruz del Islote (Santa Cruz Islet or Holy Cross Islet) is an artificial island. Its significant population (approximately 1,200) compared with its small size results in it being one of the most densely populated islands on Earth.

The islet was started by locals who used materials such as coral, debris or stones to later gain land from the sea in a part of the coast of low tide. It is believed that this first establishment dates from 1870. Due to its small size some locals would later migrate to neighboring islets such as Tintipán Island or Mucura Island.

Rosario and San Bernardo Corals National Natural Park

Rosario and San Bernardo Corals National Natural Park is located in the Caribbean Region of Colombia. Its surface area is part of the Bolívar Department, with the exception of Boquerón Island which belongs to the Sucre Department.

The park was founded in 1988 to protect one of the most important coral reefs of the Colombian Caribbean coast. it contains the most extensive, and most diverse and developed coral reef in the entire Colombian Caribbean continental coastline.

The park has an area of 120,000 sq km (46,300 sq mi), from the line of the highest tide to the beryl of the 50 m (164 ft) depth. It extends from the underwater platform and the coral reefs west from the Island of Baru, the reefs of the archipelagos of Nuestra Señora del Rosario and San Bernardo and the underwater platform in between, as well as the Tesoro, Rosario, Mucura and Maravilla islands.

This area was declared a Natural National Park due to the necessity to preserve and protect the coral reefs and the associated ecosystems, such as the sea grass and mangroves as well as the numerous species of seaweed and animals that inhabit them.

The protected area includes four islands that are designated as untouchable zones. Two are located in Our Lady of Rosario Archipelago (Tesoro and Rosario Islands) and two are located in San Bernardo Archipelago (Maravilla and Mangle Islands).

Rosario and San Bernardo Corals National Natural Park constitutes an underwater set of ecosystems and communities inhabited mainly by corals that are home to hundreds of microscopic animals, fish, crustaceans, mollusks, anemones, urchins and starfish as well as a wide range of seabirds.
