Chanthaburi, close to the Cambodian border in eastern Thailand, is a province of quiet beaches, old riverside communities and fruit orchards that supply markets across the country. Its name means “city of the moon”, and it has been a trading town for gemstones for centuries. It’s an easy place to mix sea, culture and food in one relaxed trip.
Chanthaboon Waterfront Community
Start in the old riverside quarter known as Chanthaboon, an older name for the town. Along a street of about a kilometre beside the Chanthaburi River stand rows of Sino-Portuguese shophouses and traditional wooden homes, built by families with Thai, Chinese and Vietnamese roots. Many have been turned into small museums, cafés and shops selling local snacks.
Take your time wandering and look out for carved wooden details and old shop signs. Don’t miss Baan Luang Rachamaitri, a historic house whose restoration was recognised with a UNESCO heritage award. The community is quiet in the mornings and livelier at weekends.
The Cathedral of the Immaculate Conception
Across the river, linked to the old community by Niramon Bridge, rises the Cathedral of the Immaculate Conception (in Thai, Asanawihan Phra Nang Maria Patisonthi Niramon). Inaugurated in 1909, this neo-Gothic church with twin spires is one of the largest Catholic churches in Thailand and a reminder of the area’s long Vietnamese Catholic heritage. Visitors are welcome outside service times; dress modestly and keep your voice low inside.
The gem district
Gems have been mined and traded in Chanthaburi since at least the 15th century, and today the town is one of Thailand’s main centres for cutting and dealing stones. The action is centred on Si Chan Road, nicknamed “Gem Road”, and the lanes around Trok Kachang. From Friday to Sunday, dealers set up tables covered in rubies, sapphires and other stones, and buyers inspect them closely with tweezers and magnifying loupes. Trading is usually busiest from mid-morning to early afternoon.
It’s fascinating to watch, but unless you really know your stones, think twice before buying anything expensive. Stick to established shops and ask for a certificate from a recognised gem laboratory.
Beaches and the coastal road
Chanthaburi’s coastline is calm and uncrowded compared with better-known resorts. The Chaloem Burapha Chonlathit Road, a scenic coastal route through Rayong, Chanthaburi and Trat, makes a lovely drive, with sea views, seafood restaurants and viewpoints such as Noen Nang Phaya along the way.
Hat Chao Lao in Tha Mai district takes its name from lao, sharp wooden stakes once planted along the shore for fishing. Ao Khung Wiman in Na Yai Am district is a gently curving bay with soft sand and clear water, with resorts, homestays and seafood restaurants nearby. The sea is usually calmest from around November to May.
Fruit season in the orchards
Chanthaburi is famous across Thailand for its fruit, above all durian and mangosteen, along with rambutan and salak (snake fruit). The main harvest runs from roughly April to June, with some fruit continuing into July depending on the variety and the year. During the season, many orchards welcome visitors for tastings, and roadside stalls sell fruit straight from the farm. Fruit fairs are often held in the season too, so check local listings for dates before you travel.
Planning your trip
Chanthaburi is a few hours’ drive east of Bangkok and easy to combine with Rayong and Ko Samet on an eastern seaboard road trip. A car is the best way to reach the beaches and orchards. Stay in town for the riverside community and the gem market, then spend a night by the sea. Our Chanthaburi province guide has more ideas.
