Visited this site in July 2018 as my last WHS in Beijing.

I took the metro YanFang Line to the second last station FangShanChengGuan and changed to Fang38 bus which go straight to the entrance of the site. I was told by the front desk that the whole site is under renovation, which has been going for 2 years and no sign of completion. And she even emphasized that the only thing to do inside was to "go hiking".

Since I was already there I decided to go in. The main site where they found the skulls was closed down and under construction, but you can still go up the path leading to the observation deck where you can take a glimpse of how it's like in the past. The same path will lead you to more sites and caves. It's recommended to go to the museum first so that you know what kind of fossils were found in the specific sites. 

There was nobody at the site and I enjoyed my afternoon taking photos without anyone running into it. The museum, on the other hand, has more visitors compare to the site mainly because it's air conditioned on a hot summer. You can find a lot stone tools and animal fossils including a complete tiger fossil. Worth a visit.

Do bring food and water if you planned to stay longer as you have to walk a bit to the nearest restaurant or convenient store.
