The entire Third Rock staff was friendly and helpful. Just before the trek, Mr. Naba answered all my questions and ensured that I will enjoy myself to the fullest. He cleared me everything about the trip, the operation, the guide, the driver and my porters. I was provided the best tour guide. He made my day with his smile and cool nature. He was really knowledgeable and attentive. He provided me all the information about the trip to Bhutan and Nepal. Thanks, Third Rock Adventures.
