The countryside scenery is just unbelievable. Caution is needed, however, especially on busier roads as traffic can be very undisciplined. 

Mountain biking is possible for the adventurous travellers, especially the north western mountains and the Central Highlands. The reward is fresh natural scenery and exotic ethnic encounters. Bicycle hire is widely available.

Vietnam has very diverse terrains which range from flat plain to rugged mountains. The natural scenery is stunning and the local culture is untouched. Motorbiking lovers will find many opportunities in Vietnam.
