Sa Kaeo Province

The province's northern terrain is dominated by the forested Sankamphaeng Range and the Dongrek Mountains, while the southern foothills are largely agricultural. Two major national parks operate here: Pang Sida National Park (844 sq km) and Ta Phraya National Park (594 sq km), protecting significant areas of dry evergreen forest. The Prasat Khao Noi Si Chompu, a Khmer temple ruin, appears on the provincial seal and reflects the strong ancient Khmer influence across this border region. Historical border conflicts left substantial landmine contamination in some areas, though demining efforts have continued for decades. The Aranyaprathet border crossing with Cambodia is one of the busiest land crossings in Southeast Asia and a major hub for cross-border trade.
