Sukhothai - Pai looking for a nice place to stay in between

We are traveling from Sukhothai to Pai by car and are looking for a place in between, because we do not want to drive such a long distance in one day.

Does anyone have a suggestion for a nice stop were we can for example walk a nice nature trail in the afternoon and sleep there before we continue our trip to Pai the next day.

Thanks in advance

Esther
