This is a series of arched bridges leading to a small coral island that was once a promontory joined to the mainland. The island's three large stone formations have been likened to the three immortals of Chinese mythology – hence the name. The sight of the old-fashioned pink-and-green bridges with waves crashing on both sides, and the shapely pebbled beach leading to them, are almost surreal, making Sansiantai a very charming spot to wander in. Go to catch the sunrise or the sunset.
On holidays and weekends Sansiantai is a bit of a madhouse with the tour-bus crowds.
