Traveling solo in Bhutan is safe. Once you book your trip with a tour operator, they will provide you a tour guide and a driver who will accompany you till your Bhutan tour finishes. You need to take note that there aren’t many places in the world where people are as courteous, caring and nonviolent as in Bhutan. When you take on the streets in the evening for a quick stroll, people will come outside to spark up conversations with you, but they will never harass you or make you feel uncomfortable.
