In September 2010, I and my two colleagues from medical school completed the Everest high passes trek + Island Peak summiting for 25 days with Nepal Hiking Team (NHT).
Without hesitation, I give NHT my highest recommendations. I recommend NHT to everyone intending to visit Nepal thanks to their friendliness, helpfulness, knowledge, and professionalism.
From the moment of arrival at Kathmandu international airport, we were welcomed and transported to the hotel where we were staying before taking off to the mountains. (Hotel Del-Annapurna, one of the finest hotels in Kathmandu, housing all the thinkable facilities needed. And with an outstanding breakfast buffet:-)
At every step of this trip, we were extremely well taken care of. We were provided with a highly experienced and very good English-speaking mountain guide. Thanks to his huge experience we got loads of nice information about the local people, the landscape, the mountains, etc.
Everyone reacts differently to high altitude, and our guide was very careful to make sure that we were feeling well every day while ascending further up the mountains. He had all knowledge necessary to notice and treat/prevent altitude-related problems.
(As a 5th-year student of the Medical University of Gdansk (Poland) I believe it is essential that you get a guide who is familiar with altitude sickness because this can happen to anyone if not careful enough.)
Food and accommodation were way over our expectations. Every day on the trek, we got to choose whatever we wanted from the menus at the local tea houses. Every night we were accommodated in very comfortable beds. At the summiting of Island Peak, we were provided with an excellent climbing guide and good climbing equipment.
We are all very much looking forward to going back to Nepal to explore other regions of this amazing country, and when we get back, we will be very happy to be clients of the Nepal Hiking Team again.
