Suvarnabhumi Airport (BKK): International travellers normally fly into Bangkok then transfer by domestic flight to Udon Thani or use rail/bus services to reach Udon Thani and onward local transport to Nam Som; surface travel from Bangkok will take significantly longer than flying to Udon Thani first.

By Train & Bus
