Sapa is exactly a mountainous area of Northwest Vietnam. The whole Sapa District is dominated by the Hoang Lien Son mountain range which is at the Eastern extremity of the Himalayas, being famous with the Vietnam’s highest mountain of Fa si pan at a height of 3,142 m above sea level. The town of Sa Pa lies at an altitude of about 1,600 m, bringing in a cool and foggy site of Sa Pa. Its location is in Lao Cai Province, north-west Vietnam, and 350 km north-west of Hanoi, close to the border with China. Sapa is famous both for its fine, rugged scenery and for its rich cultural diversity. French used to consider Sapa as Summer Capital of Northern Vietnam in the early decades of the 20th century. Its naturally gifted beauty keeps attracting more and more people to spend their vacation there since then.
Sapa takes its pride in its unique climate in Vietnam. It is highly seasonal, with a subtropical climate in the summer and a temperate climate during the winter. Mean annual temperature for Sa Pa town is 15.4°C, with a maximum of 29.4°C and a minimum of 1°C. The warmest months are July and August, and the coldest months are December and January. Snow falls in some years on the highest peaks. In the morning and afternoon, it is as cool as in spring and autumn. Yet, at noon, it is as sunny and cloudless as in summer. In the evening, it drastically changes into coldness just as in winter. This is actually a unique advantage, making Sapa different from anywhere else in the nation. However, travelers should be noticed that there might be sudden thunderstorm and heavy rains at noon in summer. Yet, subsequently, a rainbow appears turning Sapa into a beautifully magic land with seven colors! So, remember to bring your best camera so as not to miss this magnificent view!
April and May are the best time for tourists to watch the most scenic beauties of Sapa, or else it might be cold and foggy before that and rainy after that. During these two peak months, the town is blossoming with pink and white flowers, and green pastures in valleys. The clouds that settle in the valley in early morning would quickly disappear.
