Do not collect beaches
Swim by the flags and the sea. Kerama, Minna, Tsuken and Kudaka are boats — not a driving detour.
Read the flag on the beach
Whether you can swim is that beach’s flag and lifeguards that day. Emerald Beach is next to the aquarium and is still a swim — do not add Kouri Beach and change twice. Aharen and Ama are the sand of a boat day, not an extra stop after Chatan’s sunset.
