Within easy reach by bus from Khammouane is Savannakhet province. Positioned between Thailand and Vietnam, the province acts as a useful trading junction between the two. Most of the town’s architecture is French colonial, including a large Catholic church, although there are several buddhist temple buildings worth seeing, such as Wat Sainyaphum. It is possible to walk the Ho Chi Minh Trail, a former clandestine route used by the North Vietnamese Army to transport military gear to South Vietnam. The trail was bombed by the USA during the Vietnam war and parts of this devastation can still be viewed. However, the trail must be seen with a guide as large parts of the route still contain unexploded bombs.
