About Rainbow Arch
Rainbow Arch is a boat-entry arch dive in Aigaura, Minami Ise, built around a massive overhead opening covered in colorful soft corals. The site is appreciated for easy navigation through the arch, making it more about clean lines, soft-coral color, and close-up subjects than complex route-finding. Rock lobsters, eels, shrimp, and nudibranchs are the standout macro life, with the arch also working well for wide-angle framing. It is a solid Minami Ise boat dive when you want sheltered structure and spring-to-fall color.
