My name is Dario. I’m from Como, Italy. If you are going to trek in Nepal.
I take some minutes to recount you my experience. With 4 friends I trekked Upper Mustang last November. Our agency was Higher Limits Trek and it was a great choice. Gopi is a very reliable and friendly person. He was very good at organizing the trek and fulfilled patiently all our requests.
We had no problem in anticipating him money for the trekking permit (550 $ per person!). He made also our stay in Kathmandu very comfortable.
We asked him a reliable guide and so he was. Our guide was always friendly and professional. He successfully solved some unexpected problems (rent a horse when a friend was sick, found soon a jeep when our return flight to Pokhara was suddenly cancelled due to foggy weather).
If I ever return to trek in Nepal I will choose Gopi and his company Higher Limits Trek again. If you have questions, feel free to ask. From now I wish you all a great Himalayan experience, like the one I had.
