The long sandy strip off the city centre at Sanya Bay is where you’ll find crowds of mostly mainland Chinese tourists kicking back. In little covered areas locals play music, sing, write characters in the sand and so on. There’s a long pathway for strolling in the cool evenings, and if the tide is out a little, you can walk on the sand for many kilometres. In the evenings it’s fun to watch the lights on Phoenix Island (the awesome cruise-ship terminal).
