My husband and I will be in Hong Kong in October. We are planning on going to Sai Kung and wanted to get information on boat tours to some of the islands near Sai Kung. Are there any boat tours that are recommended? Also information on ferry to Sharp Island? Also is there a ferry to Kau Sai Chau? I heard that there are lady's at the piers who arrange sampan boat tours but need to tell them which islands you want to go to. What islands do you recommend and how much should those tours cost? Also, do I need a full day in Sai Kung? Any info would be great.
