About Travel to Ubon Ratchathani
There are two main reasons foreign tourists come to Ubon Ratchathani: to visit the local temples and to travel to Laos.
Travel to Pakse in Laos
There are regular bus services from Ubon Ratchathani to Pakse in Southern Laos (subject of course to covid-19 travel restrictions). The journey by local scheduled bus service from Ubon Ratchathani to Pakse takes around 2 hours inclusive of the time it takes for all passengers to pass through both sets of immigration controls.
The benefit of travelling to Laos via Pakse is that you are close to two of Southern Laos’s main tourist attractions: the Bolaven Plateau, famous for its waterfalls and motorbike route, and the 4,000 Islands region right at the southern tip of Laos.
Travel to Don Det
Bus services from Pakse to Don Det, the main island in the 4,000 Islands, take 3 hours 30 minutes. Travel by road in Laos is very slow compared to travel by road in Thailand so if you are planning to travel overland from Thailand to Don Det the fastest way to do it is to travel via Ubon Ratchathani.

Temples in Ubon Ratchathani
Ubon Ratchathani also has some great temples, and it’s a place in Thailand where foreigners with a serious interest in learning about Buddhism often choose to come. Wat Pah Nanachat in particular is notable for offering courses in Buddhism to foreign visitors. People interested in Buddhism will also want to visit Wat Nong Pa Phong, which is one of the main centres of the influential sect of Forest Buddhism in Thailand.
Visitors, however, who are more interested the architecture and the artwork than the religion will most likely find a visit to the recently constructed Wat Sirindhorn Wararam and the magnificent Wat Phra That Nong Bua more rewarding.
