A legendary, remote marine park consisting of two volcanic islets (Big Brother and Small Brother). Known for iconic British-era lighthouses, world-class wreck diving (Numidia and Aida II), and pristine, colorful walls. Famous for heavy pelagic action, including schooling hammerheads, thresher sharks, grey reef sharks, and oceanic whitetips. Note: Experienced divers only; strong currents and deep drift diving are standard.
