About Udon Thani
Udon Thani is a lively town with a city centre population of over 130,000 permanent residents.
Udon Thani City Centre
The busiest part of the city, and the most popular with foreign visitors, is around the railway station. Next to the railway station are several busy night markets and a short walk from there is the Samphan Thamit Alley which has lot of bars, restaurants and hotels catering principally to foreign visitors. The city centre itself has a limited number of tourist attractions. The main temple in the city, Wat Pothisomphon, is worth visiting as is Nong Prajak Park with its incongruous giant yellow plastic ducks floating in a boating lake. The main attraction of the city centre to foreign visitors is the lively authentically Thai atmosphere and the city’s shops and other amenities which are much better than those available in much of the rest of the North Eastern Region of Thailand.

The two major tourist attractions in Udon Thani Province are some distance from the city centre and you need to work hard to reach them by public transport if you do not have your own vehicle, which is why they not visited as much by foreign tourists as other attractions in Thailand:
- Ban Chiang National Museum: Musuem dedicated to the hugely important archaeological finds in Ban Chiang Village which redefined our understanding of early civilisation in the region. 50 km from Udon Thani city centre.
- Wat Kham Chanot: Quirky temple 88 km by road to the north east of Udon Thani city centre. Few foreign visitors make it to this temple which is hugely popular with Thai visitors. Wat Kham Chanot is, according to local legend, the home of the mythical naga with a portal to the under world from whence the naga came located in the grounds of the temple. Part of the temple is in a forested area believed to be inhabited by ghosts where Thai mystics conduct mass blessings of visitors.
