We did a 9 days tour to Nepal and Bhutan with Third Rock Adventures. Our guides in Nepal and Bhutan were marvelous - attentive, patient & informative. We stopped along the way on daily routes for some incredible scenery. The historical and traditional ambiance of Nepal and Bhutan were truly amazing. The scenic beauty of nature was also equally beautiful. Had a clear view of the majestic Himalayas. I would say this is definitely a must-do tour. The staff took care of us very well and we recommend their services to others.
