couldn't find the Lonely planet forum but tracked down their facebook page https://www.facebook.com/pages/Bohem...65940790123082

www.lonelyplanet.com/thorntree is the Lonely Planet forum. Given the reviews above, I don't know why anyone would be interested in Bohemian Tours Facebook page!!

I traveled on the Bohemian Tours Nepal trip in May 2012. I completely enjoyed myself but THE TOUR IS NOT FOR EVERYONE. I am a rough and tumble girl from the Colorado mountains. Many -- most-- of the people on the trek were physically struggling and had to hire ponys. Add on top of it the 99.9% chance that you will have dysentary during all or a portion of the trip. I would suggest arriving 7-10 days prior to the actual commencement of the trek, just to adjust to the food preparations and different way of cleanliness.
I, personally, had a blast. But keep in mind out of probably 36 people (broken into 3 groups) probably only 33% were able to complete the entire trek.
