There are two routes that you can take to reach Bhutan: By Flight
You can reach Bhutan directly from Bagdogra Airport. Just keep in mind that you should book the tickets in advance, as the flights travel to Bhutan two to three days a week. Another way is to travel to Bagdogra Airport from any major airports of India and take a private taxi to Phuentsholing, which may cost you around Rs 1700/- to Rs 2000/- to reach your destination. By Train
You can take any train that is going to NJP/Guwahati/Kolkata and get down as soon as the train reaches Siliguri or Hasimara station. Once you reach there, take your next bus to Jaigaon, which is the border town that connects Bhutan and India, and eventually, you can enter Bhutan through Bhutan Gate.
