Wat Sa Si is one of three not to be missed temples of Sukhothai. After Wat Mahathat and Wat Si Chum it's easy to place Wat Sa Si as the third "must see" temple in Sukhothai Historical Park. Set on two small moat islands it looks great close up and from a distance across t h e water. It's nickname is "Sacred Pond Monastery". To access the main chedi, you pass by a photogenic red wooden bridge. Wat Sa Si is just next to Wat Mahathat, so the best is simply to bicycle around these 2 places passing all the palm trees, it's so peaceful and beautiful and you can stop anywhere you want for pictures. And of course the best time is around sunset/sunrise. Bring some drinks and some snacks, sit down in the grass and enjoy the views!
