How much time do I need to see Sado

I don't know much about Sado yet as I'm just starting to research. I do need to know as soon as possible exactly how much time I'll need to see the sights. Could someone help me on that?


There’s a tour bus that operates out of the port. It’ll take you to see just the main sights in one full day or half day tours. If you're looking for the minimum amount of time, that would be your best choice.
