As one of the largest in Ha Long, Bo Hon Island or Soap-Berry Tree Island is famous for not only its splendid scenery but many famous and fascinating grottoes. It is about 1.5 hours from Bai Chay although we took much longer to reach it, as we were cruising slowly and enjoying the view along the way.
There are many grottoes located here, such as the Sung Sot (Surprise), Luon, Trinh Nu(Virgin) grotto. Each of them has their own marvellous beauty and is related to the moved legends.
 
Besides, a lot of high mountains with vertical cliffs like citadel wall; mountains follow closely make a huge beautiful watercolour picture on the sea.
 
The island is also home to various species of plants such as benjamin fig trees, cycads and orchids... and animals are monkeys, deer and chamois.
