Voeun Sai District is a remote and picturesque area located in the northeastern part of Cambodia, within Ratanakiri Province. Known for its unique landscapes and cultural diversity, the region is home to several ethnic minority groups, including the Tampuon, Kachok, and Kreung, each with its own distinctive customs, languages, and traditions. Voeun Sai is set amidst rolling hills, dense forests, and the Sesan River, which is a significant waterway providing livelihoods and transportation for local residents. The district is also noted for its natural attractions, such as the majestic waterfalls, hot springs, and the nearby Virachey National Park, which is one of the most biodiverse areas in Cambodia and offers opportunities for ecotourism and wildlife observation. The district's economy is primarily based on agriculture, traditional crafts, and increasingly on tourism. Visitors can explore ethnic villages, participate in traditional ceremonies, and trek through the stunning landscapes. Due to its remote location, the infrastructure is limited, and access to the district can be challenging during the rainy season, yet this seclusion adds to Voeun Sai's charm and appeal.
