Located 10 minutes by bicycle from the central part of Sukhothai Historical Park, Wat Chetuphon is one of the most interesting temples outside the paying areas. Very in ruins, it is interesting for its 4 different large Buddha statues: one walking, one standing (two back to back), one sitting and one lying. They are very damaged and have not been restored but you will not find the equivalent in the paying areas.
If you are planning to go to the Buddha amulets making workshop near Sukhothai Historical Park, Wat Chetuphon is just
500 meters after on the main road.
