A circuit connecting three UNESCO World Heritage historical parks in Thailand's central plains — each a capital of a different Siamese kingdom era. Sukhothai, the 13th-century birthplace of Thai civilization, anchors the route. Si Satchanalai to the north preserves the original Sukhothai-era kiln towns amid jungle ruins. Kamphaeng Phet to the south has the most complete surviving ramparts. All three parks are best explored at dawn before heat and tour coaches arrive.
