Discovering Old Providence McBean Lagoon National Natural Park
This protected area in unique and is the only one in the insular oceanic Caribbean of Colombia. It is located northwest of the island of Providencia archipelago of San Andrés, Providencia and Santa Catalina. The park has an extension of about 9,95 km² of land area of which 9,05km² are marine area.
The small part of its land area is known as Iron Wood Hill, which has the second largest barrier reef in the Caribbean, after Belize, protecting the coasts of the island of Providencia. Thanks to the large coral reef in this area, its waters turn from a dark blue to a translucent turquoise blue; that is why it is known as “the Sea of 7 colors“.

The park has 4 ecosystems of the archipelago that can be appreciated during the traveler’s visit: mangrove forests, coral formations, seagrass meadows and a small extension of dry forest.
