I see many posts about the dams on the Nam Ou and it sounds like this is no longer possible. What are some other good bike/boat routes that are still available for a couple days float? I was thinking Pakbeng to Luang Prabang, since I need to be in Luang Prabang once Vietnamese Immigration opens after the 15th (New Years break 2/6/16-2/15/16). I could be in Pakbeng in a day or two. Any other tips would be greatly appreciated, since I have not loaded my bike on anything other than ferry crossings. Thanks!
