After claiming the cache, continue on the paved path, or if you're like me, take the dirt path to the summit of Bai'ta'shan(白塔山)and enjoy the view from the top.
Beijing Xi'shan National Forest Park(北京西山国家森林公园)
This park is located just outside the west 5th ring of Beijing, neighboring the famous Fragrant Hills. If you enjoy the great outdoor but are discouraged by the traffic jam and over crowded park next door, come visit, I guarantee you'll have a much more relaxing experience here.
During the blooming months, you can also enjoy the seasonal flowers display throughout the park.
Note: I've used a ziplog bag over the cache container, but the one I had with me was just about big enough, if you're there next, please replace it with a bigger one.
