About Garden Eel Cove
Garden Eel Cove is Kona's best-known manta night dive, built around a sandy bowl where divers settle in around a light source while mantas sweep overhead to feed on plankton. The site is simple in layout, highly structured in how operators run it, and focused more on calm positioning and animal behavior than on covering distance underwater.
