I did this with a travel company who organise group tours. If i ever went back I would do it on my own. It’s so easy to get around, meet people and get accommodation!! I loved Thailand and can’t wait to go back! I particularly liked the Koah Sok National Park, a beautiful place to rest and contemplate for a few day! I found Phuket a little intimidating for a female on your own and didn’t particularly like Bangkok because of the pollution and people trying to con you – especially tuk-tuks and taxis. I loved Chaing Mai-so recommend the hill-tribe trek! Don’t pack to much because you can buy anything cheaply out there. Don’t drink the water!made me ill!! The food in Thailand is amazing, such good food!
