Thai Airways (; tel. 02356-1111) offers daily flights to the area, as do budget carriers Nok Air (; tel. 1318) and AirAsia (; tel. 02515-9999). Numerous trains (best as an overnight in a second-class sleeper) connect from Bangkok’s Hua Lampong Station (tel. 1690) daily via Khon Kaen, and there are bus connections from Udon across the region. All transport options cost less than 1,000B (with some 11-hour bus routes selling for 400B), so pick based on your timetable; a one-hour flight or nine-hour bus or train. Major car rental companies, like Budget Car Rental, have offices at the airport and online reservations aren’t necessary. This option is best for travelers setting off on a multi-city Isan tour. If you just plan to hangout in Udon Thani, the best way to get around the surprisingly sprawling town is by tuk-tuk, which, oddly, are called “skylabs” here. From Udon Thani it is easy to explore the Mekong Valley to the north (see the following sections).
