The Best Things to See and Do in Isaan: Northeast Thailand’s Authentic Gem
Experience the vibrant culture, ancient ruins, and mouthwatering cuisine of Isaan—the undiscovered heart of Thailand.
Northeast Thailand, better known as Isaan, remains one of the country’s most authentic and culturally rich regions. Far removed from the throngs of international tourists that flock to Bangkok, Chiang Mai, and the beaches of the south, Isaan offers visitors a rare chance to experience Thailand’s true heartland—where vibrant festivals, ancient ruins, vast rice paddies, and warm village hospitality reign supreme.
Introduction to Isaan
Isaan covers Thailand’s vast northeastern plains, bordered by Laos and Cambodia, and is famous for its unspoiled landscapes and deep-rooted traditions. Home to approximately 20 million people, Isaan’s population is spread across fertile rice fields, low rolling hills, and bustling market towns. The region’s culture stems from a blend of Thai, Lao, and Khmer influences, visible in its festivals, food, architecture, and language, which is closer to Lao than standard Thai.
Despite its size and historical importance, Isaan receives a fraction of Thailand’s tourism, making it the perfect destination for those seeking genuinely local experiences—whether that’s participating in centuries-old celebrations, savoring fiery som tam (papaya salad), or exploring crumbling Khmer temples under the open sky.
Top Historic and Cultural Attractions
Isaan’s long history is visible in its monumental Khmer ruins, prehistoric archaeological sites, and vibrant spiritual traditions. Below are some not-to-be-missed highlights:
- Phimai Historical Park (Nakhon Ratchasima):
- Known as “Thailand’s Angkor Wat,” this extensive 11th-century Khmer complex showcases elaborate carvings and is one of the best-preserved sites in the region. The imposing central sanctuary is a masterpiece of ancient engineering and art.
- Prasat Hin Phanom Rung (Buriram):
- Set atop an extinct volcano, this dramatic sandstone temple complex dates back to the 10th-13th centuries. Visitors can walk up a ceremonial stairway flanked by naga balustrades, and enjoy sweeping views over the countryside.
- Ban Chiang Archaeological Site (Udon Thani):
- A UNESCO World Heritage Site, Ban Chiang’s excavations have yielded pottery and tools dating back over 5,000 years, revealing Southeast Asia’s prehistoric roots.
- Wat Phra That Phanom (Nakhon Phanom):
- Considered the grandest temple in the northeast, this riverside stupa is a revered pilgrimage site, said to contain a relic of the Buddha.
- Nong Khai’s Sala Kaew Ku:
- A surreal sculpture park displaying massive Buddhist and Hindu figures, created by mystic Luang Pu Bunleua Sulilat, right on the banks of the Mekong River.
Natural Wonders
Isaan is blessed with pristine national parks, mighty rivers, and scenic plateaus. Outdoor enthusiasts can find adventure and tranquility in equal measure:
- Khao Yai National Park:
- Thailand’s first national park and a UNESCO World Heritage Site, Khao Yai is noted for its lush forests, waterfalls, and wildlife, including elephants and hornbills. The park is easily accessed from Nakhon Ratchasima (Korat).
- Phu Kradueng National Park (Loei):
- Famous for its challenging hikes, panoramic mountain vistas, and cool climate, Phu Kradueng is a favorite among Thai adventurers—perfect for trekking, camping, and spotting rare orchids.
- The Mekong River:
- The mighty Mekong carves the natural border with Laos and is lined with tranquil towns like Chiang Khan and Nong Khai. Its banks are ideal for cycling, boat rides, and riverfront markets, especially during sunrise and sunset.
- Sam Phan Bok (Ubon Ratchathani):
- Nicked-named the “Grand Canyon of Thailand”, this unique stretch of the Mekong is famous for its thousands of potholes and rock formations revealed in the dry season.
Unique Isaan Festivals
Isaan’s calendar is packed with lively and sometimes unconventional festivals. If you time your visit right, you’ll be swept up into a world of music, dance, and age-old rituals:
- Yasothon Rocket Festival (Bun Bang Fai):
- Held every May, this raucous rainmaking festival involves villagers launching enormous homemade rockets for good agricultural fortune. Expect colorful parades, dancing, and lots of revelry.
- Phi Ta Khon (Ghost Festival) in Dan Sai:
- Drawing crowds in June or July, participants wear haunting masks for traditional processions and dances, invoking spirits to bring rain. This is one of Thailand’s most distinctive and photogenic festivals.
- Ubon Ratchathani Candle Festival:
- Every July, intricately carved candle floats parade through the city, marking the start of Buddhist Lent with music and dance performances.
- Naga Fireball Festival:
- In October, thousands flock to the Mekong banks near Nong Khai to witness mysterious, glowing fireballs rising from the river—a mesmerizing, unexplained phenomenon rooted in local legend.
- Surin Elephant Round-Up:
- November sees Surin’s spectacular (if controversial) celebration, featuring dozens of elephants performing parades and demonstrations. It’s as much a showcase of the area’s ancestral mahout culture as an opportunity for scrutiny over animal welfare.
Authentic Isaan Cuisine
Isaan food is a highlight in its own right, famed across Thailand for its bold flavors, fiery chilies, and abundance of fresh ingredients. Dining in small restaurants and roadside stalls is a daily ritual, with the following dishes not to be missed:
- Som Tam – Green papaya salad, pounded with chili, fish sauce, and lime.
- Larb – Spicy minced meat salad, usually with pork or chicken and plenty of herbs.
- Sticky rice (Khao Niew) – Served with nearly every meal, often eaten by hand.
- Gai Yang – Grilled chicken, marinated and smoky from roadside barbecues.
- Sai Krok Isan – Soured, garlicky pork sausages, grilled and served as snacks.
For the adventurous, local markets also offer edible insects, bamboo worms, and even frog dishes—true delicacies in Isaan. Meals are often communal, and guests are welcomed to join in, especially in the smaller villages.
Exploring Villages and Homestays
Experiencing rural life is a must in Isaan. Staying in a guesthouse or homestay allows travelers to participate in daily routines, like helping with rice planting, making coconut sweets, or joining a temple merit-making ceremony. Families often supplement their income this way, and homestays are particularly popular along the Mekong near Chiang Khan and in the southern rice-farming regions. It’s here that visitors get a true taste of Isaan hospitality—informal, warm, and steeped in tradition.
