Having lived in Boulder, Colorado and traveling throughout the mountains of the North West, South West and Rocky Mountain region, I must say Sa Pa has some of the most majestic views I've ever seen. Of course, they're quite different than anything I've seen in the U.S. Everything is quite greener and the rice fields are on this graded slant up and down the mountains. Also, there's no snow, but rather some huge waterfalls scattered sporadically throughout the valley.
We decided to to half of our stay in Sa Pa in a homestay and and the other half in a hotel. The first day and a half with the homestay we fun, though we got really really wet towards the end. The rain just didn't stop. However, when we stayed with the family, the food they made us was quite nice and we got friendly with our fellow homestay lodgers from all over the world including Russia, the U.K. and France. The little girl who lived at the homestay was a complete ham and knew how to work us like a New York City street performer. She had card tricks and random beer bottle cap tricks to show us as we drank the free rice wine provided to us into the early evening. She even knew how to make the dogs do some fun tricks.
One of the coolest things about Sa Pa was the Black Hmong minority ethnic group. They originate from Southern China and have swaths of land, especially agricultural land, in Vietnam dedicated to them as minorities. They are pretty much around tourists all the time trying to sell them handmade goods when it's not one of the harvest seasons. They actually have outstanding English skills for the level of education which most of them has, which finishes around age 15, when most of them get married and start families. They pick up English man many Vietnamese people who live in major cities throughout Vietnam according to the tour guide. Goes to show what really wanting to learn a new language can do for someone and how much they're capable of if they were given real access to quality education besides access to speaking with foreigner tourists.
