With the intention of trying this trip before I arrived in Luang Nam Tha, I was very happy to see a note in the tourist office from a French couple looking for others to charter a boat with—and even happier after meeting a German/Thai couple near the boat landing who also wanted to do this. There is no longer any local passenger traffic from Luang Nam Tha, so chartering is the only way to do this trip. Going downriver from Luang Nam Tha cost us US$90 for the boat as far as Pak Tha, where the French couple and I were getting off; an extra US$10 was shared by the German/Thai couple and the last-minute arriving Dominican for the further two hours to Huay Xai.
We set off at 8:30am and sailed for around eight hours in the long, wooden canoe with two short stops. We passed a number of Khamu villages and decided to stop and visit one. However, the one we chose was deserted, save for an elderly couple! Everyone was out working in the fields. It was as if they'd heard strangers were coming and fled, leaving behind a few pigs and chickens! Our second stop was at a village that had the boarding school for the area. Our boat pilot wanted to drop something off for his son. The hundred or so kids were very curious about us, but when we moved towards them, they scattered! Some of the younger ones were very scared of us. We arrived at Khon Kham, the boat captain's village, at around 4pm, washed in the river, and stayed the night.
The village was friendly and curious, and we slept on mattresses on the first floor of the captain's family house. We were fed very well with sticky rice, wild vegetables, eggs, and larp (a minced-meat salad); Lao-Lao moonshine was plentiful but not particularly palatable! The following day, we stopped briefly at a cave system and arrived in Pak Tha around 2pm on a very hot afternoon. The scenery over the 2 days was very hilly, a continually rotating tableaux of primary rain forest, secondary growth, and cultivated fields punctuated with fishing villages and steep, craggy cliffs. Not much bird life beyond Kingfishers and Yellow and White Wagtails, but the real interest for me was observing and photographing the life on the river. In the morning and late afternoon, the men are out fishing, cutting bamboo and mending or building boats; as school finishes at midday, the kids are out in the afternoon playing on the river banks and greeting the passing tourists with frantic waving and shrieking, "Sabai Di" (Hello). It was a very quiet and relaxing trip, and the advantage over the road is that the river wasn't potholed and dusty—but my bum still hurt after two days!
