Easy-access Okinawa macro site with shore and boat options, coral growth, and a warm-water outlet that changes the local feel.
About Sunabe Water Treatment Plants
Sunabe Water Treatment Plants is a shore-friendly Okinawa macro site built around a municipal seawater intake and outflow structure that looks more like a quirky attraction than a utility landmark. It works well for relaxed scuba and snorkeling, with soft-coral growth, close-up critters, and a winter-friendly macro mix around the device when the plant is running. The appeal is easy access, photogenic small life, and a site that stays useful when cooler water pushes other dives lower on the list.
