UNESCO World Heritage Site
Thai's ancient city in middle of N Thailand. It was founded in 13 C. as the capital of Thailand. But it was completely destroyed by Burma in 14 C. And the capital was moved to Ayutthaya.
The ruins are as good as Ayutthaya but this SukhoThai was too much cleaned and became as a park. You do no longer feel history of Thailand so much.

The bus station is about 3km from New Sukhothai and 12km from the Old town. Songthaw can take you to both town from the bus station. To New town 7B and to Old town 15B. The drivers try to charge more. The information office at the bus station will tell you the right price.
