Summary: Phansipan (3143m) which named the rooftop of Indochina; is divided into two parts which having different ecological conditions: Northwest with Son La - Moc Chau tableland; and Northeast with mountains range as a convex bow-shaped toward the East and Southeast converge to Tam Dao mountain. We strongly suggest the 4 Days/ 3 nights climb for this adventure - unless you are very fit and eager to have some long and quite hard days of trekking! The climbs do not demand high technical skills of the climb.
