We just came back from our Kathmandu Valley Sightseeing tour organized by Third Rock Adventures. It was worth every minute! It was very well including great guides, transportation, food, and driver. We felt very well taken care of. Also, have to mention that the website has complete information and especially reviews. we filled the "Plan Your Trip" form and got a call in a couple of hours from them and it was an easy booking process with them. The tour was a wonderful experience. Thanks Naba and the team for this great trip.
