It seems you're asking about how Sam (likely a person or character) traveled to Hà Giang. However, I don't have enough context to identify which "Sam" you're referring to or the specific details of their travel.

If you are referring to a famous trip or a specific person, such as a travel blogger or an influencer, or even someone in a specific story, could you provide more details so I can better help you?

Alternatively, if you're asking generally about how one would travel to Hà Giang (a province in northern Vietnam), people typically travel by bus, motorbike, or car from major cities like Hanoi to Hà Giang. Many travelers enjoy taking a motorbike to explore the beautiful mountainous roads and landscapes along the way.
