Sebastian de Belalcazar Shipwreck
Hidden beneath the Pacific ocean of Bahía Solano, Chocó, Colombia, the ARC Sebastián de Belalcázar rests in tranquil retirement, its steel structure transformed into a vibrant underwater sanctuary. From serving as a formidable warship in the Pacific theater of WWII to becoming one of Colombia’s most iconic dive sites, this wreck offers a perfect blend of history, marine biodiversity, and adventure for advanced divers—whether on scuba or in a single breath.
A Ship with a Story
Originally named the USS Jircaillo, this ship was built in 1943 in the United States. It served valiantly in World War II, earning two war medals during its missions in the Far East. One of its most notable contributions was during the Battle of Okinawa, where it played a critical role in one of the largest amphibious assaults of the Pacific War.

After the war, the USS Jircaillo was decommissioned and later acquired by the Colombian Navy in the 1970s, where it was renamed ARC Sebastián de Belalcázar. As part of Colombia’s naval fleet, it gained fame for its participation in the 1981 raid on MV Karina, a supply vessel loaded with smuggled goods intended for guerrilla groups.
In 2004, after decades of service, the Sebastián de Belalcázar was retired and intentionally sunk off Bahía Solano to create an artificial reef, it stands as a testament to history and nature’s ability to reclaim human creations.
Today, this 63-meter (207-foot) warship lies in quiet repose, offering divers a chance to explore its rich history and abundant marine life.
