West of the Cambodian plain the road from Angkor crosses the Sa Kaeo plain, passes Sdok Kok Thom and the moated town of Si Mahosot, and climbs through the Dong Phaya Fai towards Lavo.
It is the last Khmer foundation country before the Chao Phraya plain. The stele of 1191 lists no rest houses on this western line; the campaign board reconstructs the stages from a scatter of small Bayon-style shrines, and the English Wikipedia Lavo article says hospitals and fire houses reach no further west than Prachin Buri. The land is a fringe of rice plain and forest with village temples, not a province in the Cambodian sense.
