We had a wonderful time in Bhutan. All thanks to Third Rock for their world-class travel services. For me, Third Rock exceled at what we expected. Surprisingly, they are a Nepali travel agency. Mr. Naba answered all my questions, about visas, permits, driving, gears, customs and everything. The guide they hired for me was a wonderful human, he was caring, friendly and experienced. He literally knew everything. He instantly answered all my questions. Everything was well managed. Thanks again.
