At Qinhuangdao, the Great Wall juts out into the sea. The original wall is long gone, but an extensive rebuilt section has been put up. Bus 25 will take you there for ¥1-3. To get onto the wall and into an area with several rebuilt halls, you need to buy a ticket for ¥60. If you're content with seeing the wall hit the sea from the other side,turn left outside the entrance and follow the road making a right turn, going through the wall and to the beach. Walk about 200m along the beach to get to the end of the wall. A fence has been put up preventing you to get closer than about 50m to the wall, however, it may be possible to go through a hole in or under the fence. Judging by its appearance, several such holes have been patched in the past, but at the time of writing (Sept 2010) there is still one there. Note that passing the fence will not lead you to the paid area, the wall itself blocks you off from that. At low tide it is allegedly possible to walk around the end of the wall and enter the paid area without a ticket. If you want to do this, make sure you understand the risk - if you get caught, you can be fined several times the admission fee.
