Wat Trapang Ngoen, imo it is the lesser visit Wat within the main zone of Sukhothai Historical Park because of its location and not well-known as Wat Mahathat and Wat Si Sawai. I visited this Wat during evening, I am the only one at the temple and I found it is very peaceful where you can listen to all the birdy chipping returning to their homes.
Wat Trapang Ngoen is located next to the lake and rubber trees. Views during sunset gave the different views compared to Wat Sa Si. You can enjoy the reflections of the opposite views at the lake.
