It's important to reach the immigration office earlier to get through the process fast. We woke up early morning and went to the office to get in first for the process. The few pre requisites for the permit are couple of passport size photos, voter id or passport original and the copy, your itenerary for the trip and details of few days' stay. The permit what you get from here is for 7 days. After getting the permit we hired a cab for the trip (We used the same cab for entire trip). It's easy to get one from nearby taxi stand. Our destination was Thimphu. The roads on the way to Thimphu are very scenic. We reached Thimphu in the afternoon and since the stay was already booked we checked in directly. After that we went to Memorial Chhorten a tourist attraction in Thimphu. In the evening we decided to just stroll through the streets of Thimphu. Since it was January the temperature was close to zero.
