I believe this is the site that is connected to the Leshan Giant Buddha. The names change, so it's a bit confusing - it might also be called the "Leshan Giant Buddha scenic area." It is a separate park, and costs 80rmb to get in (it's 90rmb to see the Buddha). I say pay the additional money, this part of the park is lovely! I bought my ticket at the tourist villa (I think it's the Vacation Village) near the bridge/city entrance, and they drove me to the South gate because I bought both tickets.
Historically speaking, there is a great representation of different Buddhas all over the mountain. You can see the giant sleeping Buddha here as well - it's the first Buddha you see if you enter through the South entrance. I thought the climb up to the main temple was especially steep - I did not see a second staircase. It's a short climb, but it's not gentle. However, for the views and the stone carvings it is definitely worth the work. There are also a couple of temples along the way.
There are food stalls, souvenir stands, and squat toilets - so it's no different from the other tourist sites in that respect. A turnstile separates Leshan park from the Scenic Park.
Downside: The maps are a little confusing.
