Well, it depends on what kind of places you like, also. If you love mountains, Northern and North Eastern of Thailand are suggested. But maybe you have heard about Thailand's famous beaches, then, Southern part of the country is a must to visit. Central of Thailand also has many spectacular sites for you to visit; the capital Bangkok, or Sukhothai: the old city.

Now you know a bit about Thailand! For more detail, I think you should be more specific about where and what you want to do to make the most out of your visit to Thailand. Please feel free to drop by and place your idea, so that we could help out :)
