Located just outside the aviary, the Zen garden offers a quiet place for contemplation. Surrounded by walls on all sides, it acts as a room itself. Covered bamboo porches lie at either end, with a bamboo walkway in between them. Small trees spot the mossy ground and there is a large circular sand garden at one end that was probably etched into a design at one point, but has since lost it. Several stone benches dot the area, allowing one to fully immerse themselves in contemplation of their surroundings.
