Serious trekking (2-3 days) in laos

My favorite trek in Laos has been out of Vieng Phouka. There is a local group trained by the European Union to do treks to benefit the local economy. Guides have been trained in English. They go to some pretty remote villages. I did a trek called the Akha trail that I really enjoyed.

I think around Muang Sing they have multiple day trips which are about 6-8 hours per day. ALso in Phonsali you should be able to arrange long treks.

Luang Namtha has a variety of small group treks, some multi-day and 6-8 hours per.

I wpould trek Phongsali reasons
1) its operated by locals so no expensive treks designed to give foreign expat western entrepeneurs western profits & prices
2) I enjoyed muan sing ethnic tribes and trek on your own, with simple map back then

some info on trekking by province on the Ecotourism Laos website.

A few yrs ago, we trekked the Ta Ong Trail , Xe Pian NPA with an overnight stay in a Lavae village (Champasak Province, Southern Laos), arranged thru the Provincial Tourism office in Pakse, very rewarding two-day trek.

I think you can find just about whatever you want. We chatted with a man who booked a 5 day trek out of Muang Sing that he tailored to exactly what he wanted. He is a trekking fanatic and was looking for something difficult and challenging. He wanted a rather obscure route he had read about in National Geographic and no one in the town knew about it. However, one company called around to their guides and found a man that knew the route. The trekking company representative even found two others willing to go with him and share the cost. They were off the very next day.

Dear Gerlinde

I'm going to f travel through Indochina and will be in Laos in a month, as you I want to go trekking.

it is pity that I could not join you ! if you will find the way please report about it.

There is some very challenging trekking north of Phongsali where you can go to remote villages that rarely see visitors, but it is expensive and because not very many people go there it can be harder to find people to trek with.
