Sorry 2 wheels the only info we have from the post is the heading of the album; Pakse Dondet Liphi Khun Pha pheng.
They come from my wife Aors friends Facebook page, we have posted for more details but she is still holidaying there so no replies yet.
I've never been there myself but recognise some of the the places with a lot less water in them. I was really thrilled to see so much water getting through to the lower reaches of the Kong with all the damming they are doing upstream nowadays.Maybe someone who has been down that way may recognise where it is.
And a couple I took from someones blog of a place I have been. Vieng Veng. Hope I'm not breeching any copyrights.
