Two days will be sufficient to tour Sukhothai ruins, though a greedy traveler’s mind like mine will crave for more. Tuktuks aren’t allowed inside the site so we hired cycles for 4 of us. The sites are scattered, 193 ruins on 70 sqkm. If you reach there with your homework done it will be easy, else the first best thing to do on reaching there will be to get hold of a good map and study the locations of the various sites. You can then plan out the tour route and make max use of the time. There are 5 main zones which you can access with a single ticket within a definite time period.
The zones are huge, spread over large area and some ruins with out any boundaries. Wat Sorasak is one such place where we didn’t need tickets. We covered some such sites at sunset and sunrise. Some of the Wats are in island, we crossed cute little bridges to reach them. All the zones offer wonderful opportunities for photography. Sukhothai is located in the north central Thailand so winters are pleasant. The rainy season is best avoided.
