Could anyone please tell me if there are any buses that run between Udon Thani and Pattaya? If there is a service for this, how long does the journey take and what are departure times from Udon.

I heard that they're Udon Thani-Rayong bus where definitely pass Pattaya. You can try call Udon Thani bus station at 042- 247950~952 or 407 Pattana Bus at number 042-243800, 249664, 242598

They have air-con bus leaving Udon Thani around 6pm until 9pm.

Or if they don't have it, you can try 407 Pattana's Nong Khai-Rayong. But I'm not sure if you'll have seat on this one.

Good luck, dear

Right, I'm sorry, I was not answer clearly.

Timetable should still be like this.

Depart Udon Thani at 08.20am, 6pm, 6.15pm, 6.30pm, 7pm, 7.30pm, 8pm, 8.30pm, and last one at 9 pm.

Fare is 305 Baht.

But I suggest you call and confirm.

Travel time, as they'll go pass Korat, to Pak Thong Chai, Wang Nam Kiew, up the mountain, to Prachin Buri and the off to the east, should take like 10 hours or so.

407 bus company runs many times day and night. Get a taxie to the bus station in Pattaya out on the Sukhumvit highway near Central. If in Udon go to the main bus staion and look for the 407 bus company. Make two trips....one to buy your ticket well in advance, you get to pick you seat. Then pack your bags and go to bus staion at required time. These buses can fill up especially around the holidays. You can request a bus that has a toliet.

good luck
