Lovely Chiringashima is connected to the mainland by a thin land bridge that appears only at low tide, when hikers, beachcombers and tide-pool explorers can walk the coral and shell-strewn connector and visit a small shrine on the island itself. Hours vary with the tides, which you may have to race if you walk too slowly. A taxi from Ibusuki Station takes 10 minutes; the over-sand hike, one-way, takes about half an hour, more if you stop along the way.
