Don Det and Don Kohn are twin islands in the Mekong River in the Si Phan Don (“Four Thousand Islands”) archipelago in Champasak Province of southern Laos. These car-free islands, connected by a small bridge at the southern end of Don Det, are magical for running, featuring lush tropical vegetation, paddy fields, and pretty views of the Mekong River. The former Don-Det Railway is now a 7 km paved path connecting the two islands. Our thanks to Lena Andersson, CEO of Go! Running Tours, for suggesting this route!

Don Det Loops

There are a couple of options for running on Don Det. A loop of the outer path is 6.4 km. A more popular route is the inner 6.7 km loop, which includes a road along the river on the eastern end of the island, then using the paved path on a former narrow-gauge railway that passes through Don Det’s interior. There are beautiful views of the fields, made more golden by the ever-shifting light. Keep an eye out for water buffalo and other wildlife! Note: From km 4, the road is not paved.

Don Khon Running

For a longer run, connect to Don Khon via the small bridge at the southern end of Don Det. You can continue along the railway path for another ~1 km, or on some other small roads at the northern part of the island. There’s a 13 km walking path around Don Khon, but it’s more rugged and less developed than the loop around Don Det.
