Hi, Depending where you are staying. 1. HK Int'l Aiport ferry to Shekou ferry terminal, 50 minutes about HKD220 1 way. However, going to downtown Shenzhen will vary from 30-60 minutes. 2. By train to Louhu, can't advise as I have never done it. This is most common for HK'ers to come in for weekend shopping. 3. Taxi direct from the airport, cost about HKD1,000. Remember VISA.
