This dive site consists of two artificial reefs located approximately 70 feet apart. The area is centered around the sunken YO-257, an old navy oiler measuring 175 feet in length, which was deliberately placed as a reef structure on August 1989. Additionally, there's the San Pedro, a decommissioned hospital ship totaling 125 feet long, that was sunk in 1996 to create another artificial reef element. Both wrecks offer unique diving experiences.
