The old town, called Muang Namtha, is located near the airport around 6 km south of the new town. This area has many shaded pathways and older wooden houses built in the Tai Yuan style. In the old town you can see evidence of the second Indochina War-two old artillery pieces stand like sentinels at the entrance to the airport.
The remains of the ancient city and temple are Khou Vieng and Vat Mahapot. This excursion help visitors to discover the little-known history of a civilization that formerly inhabited Vieng Phoukha District as early as the 15th century. Another must see in Vieng Phoukha is the labyrinth of caves fill with bats at Phou Prasat and the impressive tunnel-like formation of the Kao Rao cave near Nam Eng village.
