Si Phan Don (Four Thousand Islands)

Si Phan Don (often translated as "Four Thousand Islands") is a riverine archipelago in the Mekong River within Khong District, Champasak Province, southern Laos. Principal islands frequently named in general sources include Don Khong, Don Som, Don Det, and Don Khon. The archipelago is characterized by numerous islands and islets, many of which are seasonally submerged when the Mekong floods, and it lies along the Laos–Cambodia border with cultural and historical ties across that border. The supplied source material comprises geographical and administrative descriptions (Wikipedia and linked Wikidata) and archive items (music and a literary audio entry) that do not document specific supernatural incidents, named spirits, eyewitness testimony, or investigative findings at Si Phan Don. Reported folkloric themes in broader regional contexts sometimes include river spirits or haunted islets, but those themes are not evidenced in the provided sources. The material here therefore documents the site's geography, hydrology, and cross-border cultural significance while noting the absence of corroborated paranormal reports in the supplied notes. Recommended further research (not included in these sources) would be ethnographic fieldwork, local oral histories, and regional folkloric studies to verify any tales of river spirits (phi nam) or other supernatural traditions tied to the islands.
