The Gem City

Chanthaburi

One of the world’s great gem-trading towns, with Thailand’s largest cathedral, a charming riverside old quarter, orchards heavy with durian and mangosteen, and quiet beaches, all in the underrated east.

Travel alert · Cambodian border

Chanthaburi province reaches the Cambodian frontier. A ceasefire has held since December 2025, but the land crossings into Cambodia are closed and remote strips can hold landmines. The town, orchards and coast covered here are well away from the border and unaffected: avoid the frontier crossings and any marked military zone, and check your government’s travel advisory before heading that way. See our Health & Safety guide.

The basics

Day Trip or Overnight?

Chanthaburi is a touch too far east for a comfortable day trip, so give it a night. The old town and gem market fill an afternoon and evening, and a second day opens up the waterfalls, orchards and coast nearby.

From Bangkok

Distance from Bangkok

By roadAbout 3.5 to 4 hours, roughly 245 km (150 mi) southeast

By busRegular coaches from Bangkok’s eastern terminal

Getting aroundThe old town is walkable; a car helps for the coast and falls

Pairs well with the eastern coast, Koh Samet or Trat and Koh Chang, on a longer eastern loop.

Gems

A world gem hub

For decades a global center of the sapphire and ruby trade, with a weekend gem market where deals still happen at the curb.

Heritage

Riverside old town

The Chanthaboon waterfront is a lovingly kept community of old shophouses, plus Thailand’s largest cathedral across the river.

Fruit & coast

Orchards & beaches

Durian and mangosteen orchards, a famous fruit season, and quiet Gulf beaches a short drive south.

What to see

A Night in the Gem City

An easy overnight: the riverside old town and cathedral on arrival, the gem market if it is a weekend, and a waterfall or beach the next day. Swap the order to taste, and take whichever option suits you.

Time it for the weekend, and the fruit

The famous gem market only runs Friday to Sunday, so time your visit if that is the draw. And if you love fruit, the durian-and-mangosteen season (roughly April to June) is when Chanthaburi is at its most delicious, with orchard buffets across the province.

Don’t miss

Eat the Fruit

Chanthaburi is one of Thailand’s great fruit baskets. Two things to seek out:

Apr to Jun

Orchard buffets

In fruit season, farms across the province run all-you-can-eat buffets of durian, mangosteen and rambutan straight off the tree.

Year-round

Local specialties

Chanthaburi rice noodles (sen chan, the noodle in pad thai) and pepper are provincial specialties worth trying in town.

Side quests

Off the Beaten Path

Beyond the old town, Chanthaburi province rewards a wander: a pilgrimage mountain, a grand hilltop temple, historic coastal relics, and a hill full of old gem mines.

King Taksin Shrine & Khao Ploi Waen

Chanthaburi was King Taksin’s rallying base after the fall of Ayutthaya, with a shrine and park in town telling the story, and nearby Khao Ploi Waen adds an extinct-volcano hill crowned by a Ceylon-style chedi, ringed by the old sapphire mines that made the province famous.

Kung Wiman Bay

A quiet curve of Gulf coast with a boutique-resort feel, mangrove boardwalks and the scenic Nang Phaya Hill viewpoint nearby.

Before you go

Good to Know

Chanthaburi rewards a little timing: the gem market, the fruit season and the pilgrimage mountain each run to their own calendar.

Timing

Weekends & fruit season

The gem market trades Friday to Sunday, and durian and mangosteen season (roughly April to June) is the tastiest time to visit. The Khao Khitchakut pilgrimage climb runs only from about February to April.

Getting around

A car helps

The old town is walkable, but the waterfalls, beaches and hill temples are spread across the province, so a car or a hired driver makes the most of a visit.

What to buy

Gems, mats & pepper

Even if you don’t buy stones, Chanthaburi is known for woven reed mats, quality pepper and its rice noodles (sen chan). Buy gems only from established, reputable dealers.
