Children can join from age 10.Is it for me?Book this if you're a certified diver or confident snorkeler who wants to see manta rays in their active feeding window at night—the same boat takes both groups, so you're not separated from non-diving companions, and the resident population in Kona means the encounter is reliable rather than a long-shot chase.
