Just about every city with a large Buddhist population has some kind of giant Buddha statue that you can visit. Hong Kong is no exception, however their giant Buddha is a little hard to get to, at least by conventional forms of transportation. The giant Buddha is found near the Po Lin monastery deep in the mountains. There's also a small "village" near the Buddha that primarily exist to deal with tourist. There are also a few fishing villages in the area, but they require a bus or car to get to them. This area of Hong Kong is pretty much cut off from the city, that is unless you consider the cable car.
Likely this area would only be visited by the diehard tourists and loyal Buddhist had it not been for an extremely long cable car that takes you from the end of the metro line right to the entrance of the now tourist village. You're then about 10 minutes from base of the staircase that will lead you up to the giant Buddha statue. It is worth noting that there are a lot of stairs that you must climb to get to the giant Buddha, so those in poor health may want to skip this visit.
It should also be noted that other than the Buddha itself and the monastery, most of this village has turned into a serious tourist trap, which even includes some kind of 3D movie attraction. Prices in this village are very high, and the cheese factor is also high. The only other warning I'll give you is that the cable car ride is not great for anybody afraid of heights. It's very high up, shaky, and wind blows through the air vents all along the sides of each car. If you happen to love heights, it should also be noted that a cable car with a glass floor is available for an additional cost.
