Phayanagaraat Nature Park, also known as the Park of the Four Naga Clans, in Pathum Thani forms part of Wat Don Yai (fig.), although it is located some distance away from the main temple grounds.

To facilitate visits, the temple provides a complimentary shuttle service between the temple and the park. From the entrance, the main sanctuary is accessible via a 160-metre-long walkway known as Saphaan Kaew Nagabaat.
