The Phi Pan Nam Mountains dominate the landscape of the district.

Si Satchanalai was the second-most important town of the Sukhothai Kingdom. Reporting Roxanna Brown, David K. Wyatt places the earliest unglazed wares from the Si Satchanalai kilns as early as the mid-12th century, and notes that the oldest of them are dug into the high banks of the Yom, where fuel could be brought by boat. He holds that the industry was not yet a trade of international proportions in the first half of the 13th century, and must have grown from local to regional scale between about 1150 and 1250 to reach the size it had by the 14th, when more than 100 kilns were firing at any one time.^{[3]: 21–22} Wyatt reads Si Satchanalai and Sukhothai as a paired-city polity rather than as a capital and a dependency, and takes the pairing as the model for other twin names of the period.^{[3]: 44–45} In the account of the Wat Si Chum inscription, Pha Mueang withdrew with his men to Si Satchanalai after the taking of Sukhothai and would not let Bang Klang Hao enter the captured town until his own troops had gone; Mueang Bang Yang, from which Bang Klang Hao came, has been placed between Mueang Rat and Si Satchanalai, though Wyatt quotes its proposers calling their placements no more than guesses.^[3]: 52 The ruins of its temples are now part of the Si Satchanalai Historical Park, which is part of UNESCO world heritage site of Sukhothai.

The district was renamed from Hat Siao to Si Satchanalai in 1939.^[4]

The district is divided into 11 sub-districts (tambons), which are further subdivided into 148 villages (mubans). There are two townships (thesaban tambon). Hat Siao covers parts of tambon Hat Siao, and Si Satchanalai covers tambons Si Satchanalai, Tha Chai, and parts of Nong O. There are a further eight tambon administrative organizations (TAO).
