If you are on a backpacking trip around Southeast Asia then this could be your last pit stop before moving onto Cambodia or the first stop while arriving from Cambodia into Laos. The delta is easily accessible by road from Pakse. Si Phan Don is an archipelago of islands in the course of Mekong river, where the river fans out into a 14 kilometres stretch, creating a visual of a sea dotted with many islands, sand patches and bushes. Hence the literal meaning of Si Phan Don is the 4000 islands; many of them get submerged during the wet season. Islands of Don Khon, Don Det and Don Khong are the largest and most popular with tourists. The usual activities include swimming, kayaking, cycling, trekking or tubing. Or you can choose to be absolutely laid back and cuddle up with a book in a hammock. The serenity rewards you with the solitude you are seeking. The tranquillity of Si Phan Don will ensure you surrender to Laos one last time!
