Book with Ace the Himalaya! Professional, organized and attention to details. I used an itinerary from a US tour group and Ace duplicated the trip to Bhutan as a private for me and my husband. He was even less expensive and I was using a Nepal and Bhutan company directly. Our tour of Kathmandu was fascinating! We loved our Bhutanese team Lekden, Tshering and Sonam. We learned the culture, cooking class, astrology reading and beautiful treks. Thank you Prem!
