Sapa, one of the most attractive points in Vietnam travelling map, still has its inconvenient times that visitors should avoid. Since Sapa is a highland town, the way leading there is not easy to drive, especially in rain season, when the road surface is slippery and a little bit dangerous. The wet season lasts for around 3 months, from June to September, and it is not a wise choice paying a visit to Sapa that time. The period from June to September also coincides with high domestic season so you may expect to see more Kinh than other ethnic minorities. From September to mid-December, the weather is perfect for sight-seeing, photo-taking and camping trips, making it one of two best times to drop by Sapa.
From late December to February, Sapa has a harsh winter with temperature being practically zero and cold winds stemming from China. Thus, this time should be avoided by tourists, especially those from tropical countries. The dry season is from January to June, but from January to February, the winter still predominates in the dreaming town. March to May is another great time to come to Sapa, with sunny days, good weather and fresh air. June is an unstable month; sometimes wet season comes earlier in mid-June, so tourists should be mindful of June, too. In general, March to May and September to mid-December is two best times to visit this marvelous town.
