Simple pathways were added after the fact due to some issues with sogginess, but are done pretty well. You can never really see the entire feature in one view due to some subtle berming of the interior areas as well.
The movement and sound of water is subtle as well, with a variety of textures and smooth falls that glide along - not rushing rapids, but a trickling and bubbling that is peaceful.
Some details show the different water flow characteristics, and you see the construction technique of the individual computer-cut pieces of granite connected together at intervals - a sort of sculptural feat in it's own right.
The aerial shows the overall configuration of the oval, with some of the context of the adjacent Serpentine Lake.
Unfortunately, videos of the features didn't make it back from Europe with me - so there is the missing experiential aspects and the sound and movement of water - which is really part of the experience. If you are in the area, definitely worth a side trip to check it out for yourself
