I will stop to this place as it is on my way to go to Sukhothai.
It will take me approximately 4 hours from Lopburi to get there, but there is not a direct line, so I will have to find my way and do some changes.
The main reason why I will stop there is to visit the Kamphaeng Phet Historical Park.
We can visit it in scooter, which is very practical.
Some people will argue that it is a bit the same things than in Sukhothai but it is apparently less touristic and more wild. Then, it will be a good introduction before the visit of Sukhothai even if the remains are not as well maintained as the ones in Sukhothai.
This is a short video which will resume the places that I will visit there:
I will stay there for a day, and then I will move to Sukhothai which is a bit more than 1 hour of drive away (77 kilometers away).
