We booked 9 days holiday with Third Rock Adventures and the entire tour package was well planned with visits to Kathmandu, Bhaktapur, Nagarkot Paro, Thimphu and Punakha. The agency is professional on handling our tour and so was the guide who is friendly with great know of Nepal's and Bhutan’s culture and traditions. Next time for sure I am returning back for trek to explore more the remote Nepal and Bhutan. Highly recommended.
