Bai Tu Long Bay
After trekking, time to relax on a cruise of Bai Tu Long Bay -- further east and more remote than the touristy Halong Bay.
Three days sailing in emerald waters amongst the rugged outcrops of limestone rock called 'karsts'.
According to legend, an immense dragon descended to Hạ Long Bay (meaning ‘’Descending Dragon’’) millions years ago, dropping numerous eggs. The eggs hatched forming thousands of rocks and islands. The tail of the dragon extended far out to sea, forming Bạch Long Vĩ island (meaning "The Tail of the White Dragon"). As she returned to heaven, she said good bye to her offspring at the Bái Tử Long Bay (means "The dragon parts the offspring").
