le mieux pour s y rendre, est un train de nuit depuis hanoi ensuite sur la place principale de sapa tu pourras trouver "l office du tourisme" qui pourras t indiquer un guide pour ce que tu souhaites faire.
sapa est très touristique donc on trouve sans problèmes
There r 2 ways to go to Sapa, one, you can tak a train, second, you can use car. But with the car, the journey will be longer and more adventurous. With train, it's more comforatble you can choose. But must remember with low price, you cant have good tour. Because food's not good guide 's not enthousiate and hotel's always bad. So you must think about it! If a tour lie sapa, guide's very important,because there's a region having many cultural colors, you can choose home stay, it's interesting, you can discouver the culture of minorities in viet nam. People there are very helpful too. Go with a good agency, you can choose, bai tu long travel, reasonable price and good tour guide!
Concernant des randonnees hors des sentiers battus (comme l'a souligne michel la region est tres touristique) et des hebergements gratuits a Sapa, je vous invite a consulter le site sapatrek.jimdo.com
Je vous souhaite une agreable preparation de voyage.
