The transparent waters around the island are full of coral reefs, making scuba diving the number one activity on Ishigaki. In particular, Manta Scramble ãã³ã¿ã¹ã¯ã©ã³ãã«, just off the island's north coast, is a legendary spot for manta ray spotting where groups of manta rays are almost guaranteed during Autumn. There are a large number of dive operators and rates are more or less standardized at around ¥12000 for two boat dives not including gear rental.
