Thong Nguyen is the most popular destination in Hoang Su Phi. Since most people on a short visit will arrive from the southern end on QL2, it is the closest terraced rice field area in Honag Su Phi for them. Thong Nguyen has a lot going for it. A nice little town with fuel and stores. There is a quaint weekend market but the main draw are the bungalow communities in the hills above town. Many of these bungalows, like Binh Minh, are perched right over the rice terraces.
While you are in Thong Nguyen be shore to visit Mam Xoi a bit further up the hill from the bungalow area. Mam Xoi has the best sunsets in Thong Nguyen. The Mam Xoi Homestay, while not bungalows, is worth staying in for the amazing views and sunsets. Be sure to NOT follow the Google Map directions or you will end up in the woods (though you will pass a lovely waterfall). Just ask a local or look for the sign for Mam Xoi Homestay in the main bungalow area.
Thong Nguyen is so close to QL2 that it makes a good stop for those going to the Ha Giang Loop. It’s still a bit far for a single day at ~250km but if you got an early start you can definately use it as a stopping point.
