Fansipan mountain in sapa is branded “the Roof of Indochina” at the height of 3,143m; Fansipan is to be approved as one of the very few eco-tourist spots of Vietnam, with about 2,024 floral varieties and 327 faunal species.
The topography of Fansipan is varied. Muong Hoa Valley, at the lowest altitude (950-1,000m), is created by a narrow strip of land at the base on the east side of the mountain.
Foreigners like best to book Fansipan tours between October and December, as this period is more often than not free from the heavy rains that obstruct the jaunt. However, the best time for the trek to the mountain is from the end of February to the start of March, when the flowers all flourish and the climbers may behold the carpets of brilliant blossoms, violets and orchids, rhododendrons and aglaias.
