If you are in Okinawa, why not try snorkeling? The snorkeling spot behind Bise Fukugi Namiki is safe for children. You can feed the fish and play in the tide pools. With a guide, you can meet Nimo/ Clownfish. It is best to avoid during low tide. You will probably get hurt by the coral because it is too shallow. Parking, refreshments, and shower facilities are available.
