Si Phan Don is the southernmost point of the country on the border with Cambodia. Si Phan Don in translation means 4000 islands, which vividly describes what you will see here. The mighty Mekong River encountered rocks here and accumulated alluvial material, and cut through many streams through it. A result is a large number of fairy-tale river islands from a few square meters to 18 by eight kilometers (Don Khong). Visitors who decide to come to these beautiful islands, captivated by the charm, often stay much longer than planned.
