I've been traveling for years, and one can not overstate the professionalism and hospitality of Third Rock. I've never seen anything that approaches the level of customer service that Third Rock achieves. A truly singular experience. Naba's meticulous and consistent attention before, during, and after the tour is already legendary in my mind. And speaking of legends, my guide Surya was absolutely epic. Surya's deep understanding of the mountains, culture, and nearly encyclopedic knowledge of Buddhist and Hindu history, lent a richness to the experience that is very rare to find. We were not only trekking through beautiful mountains, but traveling through culture and history as well! Wonderful trip, most highly recommended.
