Sukhothai was the first kingdom in the area of Thailand. The ruins form an extensive historical park and the best way to explore this region is by bicycle
Sukhothai was the first capital of Siam. Since some centuries the inhabitants, fearing ghosts from the old ruins, have relocated to New Sukhothai, some 7 km away. The old ruins have recently been excavated and restored from the Thai government and UNESCO and form the Historical Park.
Due to the big extent of the area the best option to visit is by bicycle. You can rent bicycles both outside the entrance and in the new town
