Why should you go there and how do you do it right?

If you found the Sukhothai Historical Park too crowded, this would be my next recommendation. Same kingdom, same era, but significantly fewer visitors. From around 1250, it was the second administrative center of Sukhothai, and its remains lie today in the forest on the banks of the Yom River. These include dozens of temples, chedis, and Buddha statues dating from the Sukhothai period to early Ayutthaya.

Two things define a visit: Wat Chang Lom, whose chedi is surrounded by elephant pillars, and Wat Khao Phanom Phloeng on its hill, whose climb, though somewhat strenuous, is rewarded with a breathtaking panoramic view of the entire complex. Between the two temples stretch laterite, weathered rock, and shadows, and the atmosphere of the place slows the mind. The grounds are so vast that it's ambitious to explore everything on foot in a single day. Rent a bicycle at the entrance, and you'll discover considerably more.

The months of November to February are best, as the heat is not as intense then. Protect your shoulders and knees from the heat and wear light clothing.
