About Northern Arch
Northern Arch is a well-known deep dive featuring an arch formation with notable structure on both sides. The seabed drops beyond 36 m, and the northern side continues sloping down past 50 m. The site is known for encountering large pelagic fish and can have current. Sponges cover the bottom, and in summer large kingfish and snapper may cruise through the arch area around stingrays, with schools of blue mao mao also present.
