When i came in Nepal, i didn't have any plan for trekking. But Puru and his agency lead me to the way, and so i decided to go for a trek until Mutkinath with my guide Ramkumar for discover Nepal's mountains.
With my guide Ramkumar (or Ram), it was for me the perfect solution for walk with my own rythm and for have a private discussion about the nepali culture. He learnt me so many things about the food, the religion, the culture, the nature, etc...and if i needed something he always answered to my questions. He also gave me some advises about the meals, the itinary and the security. I always felt in security with Ram, during all my trek (and also after during my short visit in hospital :D).
So that's why i recommend strongly this agency and my guide Ramkumar for their serious, their offers and their good spirit.
