First, the big picture. Nong Bua Lamphu is a small province in upper Isan — uncrowded, slow-paced, known for its forest temples set among limestone, the mountain scenery around it and homestyle Isan food. Udon Thani lies about 46 km to the east along Highway 210 and is a much bigger, busier regional hub with an international airport. Plenty of travelers fly into Udon and then drive over to Nong Bua Lamphu, so this trip starts there for one night, then loops back to Udon for the rest — that way the final day stays close to the airport and getting home is easy.
Straight talk before you plan
Nong Bua Lamphu really is a small town. It doesn't have nearly as many sights or big-name restaurants as a major city, so if you're hoping for nonstop buzz you may come away disappointed. But if you like a calm town, temples in the limestone forest and cheap, tasty food, then carrying on to the fun in Udon — this pairing works beautifully. The charm is the contrast between two very different cities in one trip.
Day 1 — Nong Bua Lamphu: forest temples and real Isan food
Day one stays in Nong Bua Lamphu. The highlight is the cluster of temples and memorials around Tham Klong Phen, set in shady limestone forest, plus the bold Isan meals this town does genuinely well. Keep the pace relaxed — nothing in the province is far apart, so there's no need to rush.
Start in Nong Bua Lamphu
On getting around the province
Many of Nong Bua Lamphu's main sights sit outside town and in the forest, and public transport is thin. If you didn't drive yourself, renting a car or hiring a local driver makes things far smoother — especially if you want to continue on to Phu Kao–Phu Phan Kham National Park, which is further out.
Book the activities in your Nong Bua Lamphu trip ahead
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.
Day 2 — Nong Bua Lamphu nature, then move your base down to Udon
On day two's morning, finish off any nature or spots in Nong Bua Lamphu you haven't seen, then in the afternoon drive the 46 km down to settle in Udon, which becomes your base for today and the final day — Udon has more food, cafes and hotels to choose from.

On the Nong Bua Lamphu–Udon journey
If you didn't drive yourself, buses and vans between the two cities are the easiest option — about 46 km, roughly 55 minutes, fares in the tens of THB. But evening departures are limited, so check the latest times at the station first. If you plan to reach Phu Kao–Phu Phan Kham or explore outside town, having your own vehicle is far more flexible.
Day 3 — A full day in Udon before heading home
See Udon before you leave
If you have an extra day or want a change of scene
If you come in the cool season (Nov–Feb), set aside half a day for the Red Lotus Sea at Nong Han, Kumphawapi district, about 40 km south of Udon. The red-and-pink lotuses bloom across the whole expanse at dawn, with small boats around 150 THB per person, but you have to set out before sunrise before the flowers close. Come off-season and you'll just see open water.
Two-city dishes worth trying on this trip
Food is the heart of this trip. Nong Bua Lamphu shines on homestyle Isan cooking at friendly prices, while Udon shines on Vietnamese food and a more varied lineup of city restaurants. Here are the dishes and spots locals actually go to, ordered by how much we'd want you to try them on this cross-province trip.
VT Nam Neuang — Udon Thani
Udon's most famous original Vietnamese restaurant — the Pho Si branch earned a Bib Gourmand from the Michelin Guide. The nam neuang is soft pork, grilled just right and fragrant, served with a generous spread of fresh herbs; add moo yor and crispy tendon alongside.
Som Tam Nayok — Nong Bua Lamphu
A famous som tam spot Nong Bua Lamphu locals bring up often — fiery and fully loaded in every bite. The tam pu pla ra is rich and savory in true Isan style; eat it with grilled chicken and sticky rice. Easy on the wallet.
Tam Yam Yua — Nong Bua Lamphu
A popular Isan restaurant in the province with som tam as the star, punchy and satisfying. There's larb, koi and grilled pork neck to order alongside, in a relaxed local setting.
Tree Bar & Restaurant — Nong Bua Lamphu
A laid-back spot where townspeople meet up, combining a dessert cafe with Thai, Isan and international dishes in one place — good for an easygoing dinner in a town where late-night options are few.
Bold, savory Isan food in Udon
Udon is the real Isan deal — som tam, larb, koi and grilled pork neck, all punchy and easy to find across the city. Plenty of well-known spots stay open late; eat it with cool sticky rice.
Shrimp wrapped on sugarcane
Minced shrimp wrapped around a stick of sugarcane and grilled, faintly sweet and fragrant — a side to nam neuang at Udon's Vietnamese restaurants. Order a plate to snack on and it goes down easy.
Koi pla and jaew bong — local fare
Local Isan dishes that Nong Bua Lamphu does with real depth of flavor — punchy koi pla and rich jaew bong eaten with fresh veg and sticky rice. Homestyle cooking you'll find at Isan spots around town.
Dark-roast coffee cafes in Nong Bua Lamphu
A small town, but with several cute cafes roasting their coffee dark — some with garden or mountain views. A good place to pause between temple visits and town wandering.
Cafes by Nong Prajak Park — Udon
The area around Nong Prajak Park has several cafes — sip a coffee or matcha looking out over the lake and the big yellow rubber duck. Good for an afternoon or evening break.
Moo yor and naem — Udon souvenirs
The souvenirs to carry home: firm moo yor and naem with just the right tang. You'll find them at souvenir shops around Udon and at the famous nam neuang restaurants.
The main sights in this cross-province plan
Wat Tham Klong Phen
Nong Bua Lamphu's most famous forest temple, set in shady limestone, with an ancient drum cave, a walking Buddha carved into the rock, and oddly shaped rock gardens. It was where Luang Pu Khao spent his rains retreats.
Luang Pu Khao Analayo Museum
A memorial about 2 km from Wat Tham Klong Phen, holding the monk's relics and possessions, his old kuti, and a wax figure of Luang Pu Khao, a forest-tradition monk respected across Isan.
King Naresuan Shrine
A landmark on Naresuan Field in the town center, built to commemorate King Naresuan marching his army through and camping here in 1574. A place townspeople hold dear.
Phu Kao–Phu Phan Kham National Park
A park covering the Phu Kao range and the Ubolratana Dam reservoir shore, with viewpoints, forest trails and prehistoric rock paintings — great for nature lovers. A car helps.
Nong Prajak Silpakhom Public Park
Udon's city park around a large lake, with a giant yellow rubber duck as its landmark — a favorite local spot to relax, with cafes along the water.
Udon Thani Museum
An old yellow colonial building in the center telling Udon's history. Free, open Tuesday–Sunday, closed Mondays.
How to travel and plan the trip smoothly
- Trip direction — start in Nong Bua Lamphu for 1 night, then flow down to Udon for 2 nights, so your last day is close to Udon airport and the trip home is easy.
- Between the two cities — about 46 km along Highway 210, roughly an hour by car. The bus takes about 55 minutes, fares in the tens of THB, with several departures a day.
- Around Nong Bua Lamphu town — many sights sit outside town and in the forest, and public transport is thin, so a private car or hired vehicle helps.
- Around Udon — in-town spots like Nong Prajak Park, UD Town and the museum aren't far apart; hailing a taxi or using a ride app is easier here than in Nong Bua Lamphu.
- Flying in and out — the nearest airport is Udon Thani, with several flights a day. Flying into Udon and then driving over to Nong Bua Lamphu is the most logical route.
Straight talk
The charm of this pairing is the contrast. Nong Bua Lamphu is slow and quiet, focused on forest temples and cheap Isan food; Udon is lively, with far more food and cafes. If you expect a long list of sights in Nong Bua Lamphu you may find fewer than you hoped, but treat it as a calm place to recharge before the fun in Udon and this trip really comes together.
Rough budget for 3 days, 2 nights
- 2 nights' lodging — first night in Nong Bua Lamphu, second in central Udon. Hotels and guesthouses from about ฿450–1,400 a night.
- Food — Isan meals in Nong Bua Lamphu are very cheap, around ฿80–150 a meal; Vietnamese or city meals in Udon around ฿150–300, plus cafes and snacks.

- Between cities — the bus is in the tens of THB, or fuel and car hire if you drive, plus the cost of hiring a vehicle in Nong Bua Lamphu in stretches.
