Eastern Thailand is often described as one of the most accessible yet underrated regions in the country. If you look beyond the usual tourist hotspots, you’ll find a region rich in geography, culture, biodiversity and local traditions. This guide takes a deeper, more educational approach while still walking you through it in a practical, traveller-friendly way.
What is Eastern Thailand known for?
Eastern Thailand is a coastal and agricultural region bordering the Gulf of Thailand and Cambodia. It includes provinces such as Chonburi, Rayong, Chanthaburi and Trat.
The region is known for several defining features:

Food to Try in Eastern Thailand
One of the most rewarding parts of traveling through Eastern Thailand is the food. Because the region sits along the coast and is rich in agriculture, you’ll get a mix of fresh seafood, tropical fruits and bold Thai flavours that are slightly different from what you might find in other parts of the country.
As you move from province to province, you’ll notice subtle changes in taste, especially in how dishes balance sweet, sour, and spicy elements.
Fresh Seafood (A Regional Highlight)
Being close to the Gulf of Thailand, seafood is everywhere and often incredibly fresh.
What to try:
- Grilled prawns (Goong Pao) served with spicy seafood sauce
- Steamed fish with lime and chili (Pla Neung Manao)
- Fried crab with curry powder (Pu Pad Pong Karee)
- Squid dishes, either grilled or stir-fried
Places like Rayong and Trat are especially known for their seafood markets and beachfront dining.
Local Eastern Thai Dishes
Eastern Thai cuisine has its own identity, often leaning toward stronger flavours and fresh herbs.
Must-try dishes:
- Som Tam – spicy, sour, and refreshing
- Tom Yum Goong – a classic hot and sour soup
- Pad Thai – widely available but still worth trying locally
- Khao Pad – simple but satisfying, often paired with seafood
In coastal areas, you’ll often find these dishes prepared with freshly caught ingredients, which really makes a difference in taste.
Tropical Fruits (A Must Experience)
Eastern Thailand, especially Chanthaburi, is one of the country’s top fruit-producing regions.
Fruits to try:
- Durian – known as the “king of fruits,” strong smell but creamy taste
- Mangosteen – sweet, juicy, and refreshing
- Rambutan – slightly sweet with a lychee-like texture
- Snake fruit (Salak) – tangy and crisp
If you visit during fruit season, you can even join fruit buffet tours where you can eat as much as you like directly from farms.
Street Food and Night Markets
Night markets are one of the best ways to experience local flavours at affordable prices.
What you’ll commonly find:
- Grilled skewers (chicken, pork, seafood)
- Fresh fruit shakes and coconut drinks
- Thai pancakes (Roti) with sweet fillings
- Sticky rice with mango
Cities like Pattaya and Chanthaburi have vibrant night markets where you can try a wide variety of dishes in one place.
Desserts and Drinks
Don’t skip desserts, especially in a tropical region like this.
Try:
- Mango Sticky Rice – a classic sweet treat
- Coconut ice cream served in a coconut shell

Sample Travel Scenario
Picture starting your journey in Bangkok. Instead of staying long, you head southeast to Rayong.
You spend your first day adjusting, enjoying a quiet beach and sampling local seafood. The next morning, you take a ferry to Koh Samet where the sand is finer and the water clearer.
After a few days, you continue east to Chanthaburi. Here, you slow down, explore historic streets and visit fruit farms.
Finally, you reach Trat and take a ferry to Koh Chang, where your days are filled with jungle hikes, waterfalls and quiet sunsets.
The journey naturally shifts from convenience to immersion, giving you a deeper understanding of the region.
