Mondulkiri is a province in eastern Cambodia, established in 1961 from the eastern portion of Kratié province. It is Cambodia's largest province by land area yet the most sparsely populated, with approximately 97,857 residents across its extensive territory. The province borders Kratié to the west, Stung Treng to the northwest, Ratanakiri to the north, and Vietnam to the east and south. The provincial capital is Senmonorom. Mondulkiri's geography is characterized by highland terrain, tropical forests, and a network of streams and waterfalls. The region experiences a tropical climate with distinct wet and dry seasons, making certain months more favorable for trekking and wildlife viewing. Due to its remote location and low population density, Mondulkiri remains one of Cambodia's least developed but ecologically significant regions, home to diverse wildlife including Asian elephants, gibbons, and endemic bird species.

Mondulkiri occupies the eastern portion of Cambodia's highland plateau, bordering Vietnam along its eastern and southern frontiers. The province encompasses extensive forested terrain interspersed with cultivated highland areas and waterfalls. Its large land area combined with minimal population density creates vast stretches of protected and semi-protected forest. The climate is tropical, with a monsoon-influenced wet season from May to October and a drier season from November to April. Elevation varies across the province, contributing to cooler temperatures than lowland Cambodia, particularly at higher elevations. The terrain supports diverse vegetation zones and water sources that sustain regional wildlife.
Mondulkiri is recognized as a critical habitat for Cambodian wildlife, particularly Asian elephants, which roam the forested landscape in small herds. The province also supports populations of gibbons, wild cattle, and numerous endemic bird species. Several elephant sanctuaries operate in the region, offering visitors opportunities to observe and learn about conservation efforts. The remote, forested character of the province has made it a focal point for wildlife protection initiatives, though habitat loss and poaching remain ongoing challenges. Tourism related to elephant observation and wildlife viewing has grown, with facilities designed to promote animal welfare and support local conservation.

Senmonorom, the provincial capital, is a small highland town serving as the administrative and commercial hub of Mondulkiri. The town sits at a higher elevation than much of lowland Cambodia and has developed gradually as a base for visitors exploring the province's natural attractions. Infrastructure remains modest compared to major Cambodian cities, with limited accommodation and dining options, though this has expanded modestly over recent years to serve growing eco-tourism interest. From Senmonorom, visitors can access trekking routes, waterfall sites, and elephant sanctuaries in the surrounding highlands.
The dry season from November to April offers the most favorable conditions for trekking and wildlife observation in Mondulkiri. During these months, forest trails are more accessible, water levels are lower, and wildlife viewing opportunities improve as animals concentrate around remaining water sources. December and January typically feature the coolest, most comfortable temperatures for outdoor activity. The wet season brings heavy rainfall and challenging trekking conditions, though the landscape is lush and waterfalls are at their fullest during this period.
