From Qinhuangdao Railway Station to Laolongtou(the old dragon´s head)

Hi there! Could you please tell me how to get to Laolongtou? Except for the train. I already checked the tickets, they all ran out :(

If there´s a bus, which one to take and how long does it take? And if the taxi, can I get one that will go all the way to Laolongtou as I heard that taxis are not allowed to cross district and how much would it cost?

Thanks :)
