Isengard
Isengard is a very peaceful place. The tower can only be entered when the water level is low, so don't head there while it's raining. It is very peaceful there; nature truly is wonderful. The forest is growing back where the orcs had deforested, and the birds chirp in the spring time. There are many places you can go to find nature's beauty, but Isengard is a good choice.
