Perhaps West Lake in Hangzhou, China is the best place for viewing or having internal reflections.
We were visiting West Lake a couple of years ago.
West Lake has been named a UNESCO site. While walking around the lake, one can feel the culture of the place and the openness of the area. The view of the far away pagoda, the nearby Chinese style building on the shore and their reflection in the lake were just breath taking.
With almost no tourists around, you can feel the tranquility of the place. Here is a picture that I have posted, but this time I have flipped the picture top to bottom so the the reflection of the trees are on the top.
One of the scenic locations is where colourful kois are reared. In the picture, again, one can see the reflections of the willows. We took the opportunity to view and photograph them.
All in all, the trip was pleasant and reflective!
