The best way to take in Vietnam's jungles, mountains, lakes, waterfalls, wildlife, bird sanctuaries, rice paddies, tea plantations and remote villages is on foot.
Vietnam has countless walking trails - from Sapa in the north, through the Central Highlands, to the south around the Mekong Delta.
It is advisable and often essential to hire a local guide who knows the area. Treks can last from a couple of hours to a few days where you can camp out or stay with a family in a local village.
