The trek to Poon Hill is  one  of the  a good and absolutely amazing trip in Nepal! We had always wanted to do this trip but weren’t knowledgeable at all about the process. Just a quick email to Nepal planet treks and the trip was booked, everything taken care of for us begging till end of the treks. Poon Hill trekking is so common to the travelers that stone stages are well developed; guesthouses and citizen houses form villages at several places over the hill, just like everyday checkpoints for the trekkers.
Still, hiring a tour guide is a good choice; he can sometimes share some baggage load, assure for the right route and guarantee the safety of the whole group.
The views were amazing from poon hill and Raj could answer any questions we had. I highly recommend Nepal planet treks in Nepal and if you do use them ask for Raj!
