I came across Third Rock Adventures on a recommendation from my sister, who has used them in the past. They could not have been more helpful, efficient, and accommodating. I signed on for the trek to the Annapurna base camp but only got halfway in. My guide Babu was really helpful, proficient and friendly. They re-arranged the rest of my tour, which became one of the best adventures of my life. I went to Buddha's birthplace, the Chitwan National Park, and a number of other out of the way places, many of which found me to be the only white guy around. They are willing to work with you on everything: accommodations, meals, transportation, and anything you can imagine. I would highly recommend this company and use them again in my future trips to Nepal, Tibet or Bhutan.
