Having done 3 major treks in Nepal, I opted to do this trek with Third Rock Again because I trusted them with local guides. This time I trekked with Rishi, a finest man for trek in Nepal. Hoenstly speaking, I suggest this trek only for experienced trekkers. It is a bit challenging trek, takes you to remote and less-walked route. And make sure to go with experienced guide like Rishi who can manage everything in the moutain for you.
