Backpacking thailand 3 weeks

For three weeks backpacking Thailand, you can definitely use and adapt the above three week Thailand itineraries. The best thing for backpacking is to use night trains and night buses. You can book through 12go Asia. This way you save on accommodation and and night trains and buses are always cheaper than flights in my experience post pandemic.
