    StandoutExceptional marine biodiversity

    Toma No.1 is a good spot for newer divers in the Kerama Islands. The reef here, topping out at 18 meters, has a gentle slope. We often find schooling fusiliers and the occasional anemonefish tucked into their homes. It’s a relaxed dive, good for getting comfortable in the water.
