Isan, Thailand: The Ultimate 4-Day Itinerary for Thailand's Most Underrated Region

Most people visit Thailand for the islands. I skipped them to explore Isan — the country’s northeastern region. Isan, is one of the most underrated places you can travel to in Thailand, and after visiting earlier this year, I’m still thinking about it. This was my fifth trip to Thailand, but nothing prepared me for the beauty, peace, and kindness I found here.

No crowds, no beach clubs — just a completely different side of the country most travellers never see. In this post, I’m sharing a recommended 4-day itinerary so you can experience the best of Isan for yourself.

Best time of year to visit Isan

Thailand’s tropical climate means there’s rarely a “bad” time to visit — but if you’re planning a trip to Isan, Thailand, it’s worth knowing there are two very distinct seasons that’ll shape your experience.

Rainy season (May to November) — expect sudden, intense downpours that can roll in fast
Dry season (November to May) — hot, dry weather with barely a cloud in sight

I visited Isan in June, right at the start of the wet season, and the weather was more humid and mostly dry than I expected. I did get caught in a few heavy showers, but they never lasted long.

If you don’t mind experiencing a bit of rain, visiting during Isan’s wet season has its perks: fewer crowds and more affordable accommodation.

Things to know about Isan

Isan, also spelled Isaan, sits in the northeast region of Thailand and is actually the country’s largest region, made up of 20 provinces. Despite its size, it’s a destination most international tourists have yet to discover. The majority of visitors to Isan are domestic Thai tourists, with most people flying into Udon Thani to start their trip.

Despite being home to around 30% of Thailand’s population, Isan receives less than 3% of the country’s tourism dollars — which tells you everything about how under-the-radar this region still is.

Isan also sits right on the border with Laos, and you’ll notice that Laos influence woven throughout the local food and culture. Even the name itself has deep roots — “Isan” comes from Sanskrit and simply means “northeast“

How to Travel Around Isan

I was lucky enough to be invited by the Thailand tourism board, so all my internal travel was taken care of during this trip — but I still picked up plenty of insight into the best way to get around Isan, Thailand for anyone planning their own trip. This itinerary assumes you’re flying into Udon Thani Airport.

Hire a Private Guide

If you’re visiting the Isan region, you’ll get the most out of your trip by hiring a private tour guide. They’ll handle the logistics, share local knowledge and drive you between destinations — one less thing to think about.

Car or Motorbike Hire

If you’re feeling confident and up for a bit of adventure, hiring a car or motorbike is one of the best ways to get around Isan. It gives you the freedom to reach all the top places to visit at your own pace.

Is Public Transport an Option?

Given how vast the Isan region is, I think it’d be difficult to rely on public transport alone to complete this itinerary — you’d lose a lot of time and flexibility trying to piece routes together.

Where to Stay in Isan

There are so many incredible places to stay in Isan, and I’ve listed a few of my favourites below from my own trip. If you’d rather not spend every day driving, one option is basing yourself in Udon Thani and using it as your hub to explore the wider Isan region.

How to Spend 4 Days in Isan

Isan surprised me in the best possible way. I’ve been to Thailand countless times, but nothing prepared me for the warmth of the locals, the incredible food, and the unique beauty I witnessed on this trip. Here’s the exact itinerary I followed on my 4 days in Isan:

Day 1: Arriving in Udon Thani

Most travellers visiting the Isan region will arrive in Udon Thani, with frequent flights connecting from many cities in Thailand, including Bangkok. When you arrive, I’d recommend basing yourself in Udon Thani for the morning and checking out the famous Yellow Ducks, along with one of the best temples in Udon Thani, Wat Pothisomphon.

After lunch, head to the Ban Chiang region, about 65 km from Udon Thani city centre. Here you’ll be able to check out the Ban Chiang National Museum, where you can learn all about ancient history at this UNESCO World Heritage Site.

Then make some time to visit Wat Pa Dong Rai, otherwise known as the white lotus temple. I’ve seen many temples on my travels through Thailand, but this one felt different. A beautiful white temple shaped like a lotus flower, sitting in the middle of a lake, with no other tourists around.

Day 2: experience local village life

Wake up refreshed in Udon Thani before heading to the first stop of the day: Phu Phrabat Historical Park. This place was fascinating — if you can, hire a guide to walk you through the park that’s been sacred to monks for over 3,000 years

Then head over to Khiri Wongkot Village, home to a population of less than 1,000 residents. Here you’ll be able to immerse yourself in local life by hopping on an e-tak (a local tractor). The locals prepare lunch in the jungle, and all the proceeds from this experience go straight back to the village. It was a fun, interactive experience that I still think about to this day.

After that, travel around 45 minutes to Wat Pa Phu Kon, a pristine temple in the hills of Udon Thani. This temple felt truly unique, with soft pastel green tones set against endless rolling green hills in the background. Wat Pa Phu Kon is open from 8:30am to 5pm, and you’ll need to cover up, ensuring your shoulders and legs are covered.

Day 3: Sculpture Park and Three Whale Rock

Day 3 of the Isan itinerary is probably my favourite of all the places you’ll see. Start the day at the inspiring Sala Keoku Sculpture Park — 40 baht for foreigners or 20 baht for locals. You could easily spend the whole morning here admiring the intricate sculptures created by Luang Pu Bunleua Sulilat. Decades were spent building these sculptures, which you can walk through and admire up close. Sadly, Bunleua passed away in 1996, and his body remains mummified on site.

After leaving the sculpture park, head to one of the most iconic places in all of Isan: Hin Sam Wan, otherwise known as Three Whale Rock. When I was researching Isan, this was the part of the trip I was most excited for. When you think of Thailand, you usually picture bustling Bangkok or pristine beaches — not landscapes that look like whales.

Finish the day by heading up Wat Phu Tok. This hike has 7 levels and is home to monks who make the walk daily. There weren’t many others on the trail, but the landscape and views were incredible the higher up you go. I was with two friends, and we only made it to level 6 before heading back. If you’re scared of heights, I’d recommend skipping this one.
