Not much here! But we were sure happy to arrive after a long day on the slow boat. Would not have come here otherwise.
Didn't see anything of interest in the town.
As far as I could tell there is not much to do in Pakbeng. The only reason most people overnight here is all of the slow boats traveling from Houay Xai to Luang Prabang have to stop for the night.
Tiny town en route to Bokeo or Luang Pra Bang via slow boat on the Mekong River. Probably not much here for the typical traveller, but I enjoyed the slow boat (though wish it was only 1 day instead of 2).
