I together with my girlfriend just finished the 16-day Manaslu circuit trek organized via this company and I can highly recommend doing the same. After having visited several travel agencies in Kathmandu, we had the best feeling about trekking partners. The people in the office are very welcoming and the information provided is very informative. After visiting the office we also received all information via e-mail from Shishir. Including itineraries and a packing list.
Best was our guide Navraj. He explained to us a lot about culture and nature during the trek. He even helped us to carry some luggage during the most difficult parts of the trek.
Next trek we would definitely go again with trekking partners and Navraj!
