Chachoengsao

Chachoengsao — affectionately known to Thais as Paet Rio — is an inner-eastern province just 80 km east of Bangkok, straddling the Bang Pakong River. Its name comes from a Khmer word meaning "deep canal," and water still defines the province: settlements cluster along the Bang Pakong and a web of khlongs, and riverside fruit orchards and rice fields fill the flat, fertile landscape. "Paet Rio" ("eight cuts") recalls the days when the river teemed with giant snakehead fish so large that eight slashes were needed to sun-dry them.

For travellers, Chachoengsao is above all a pilgrimage and day-trip destination. Its spiritual heart is Wat Sothon Wararam Worawihan, home of the revered Buddha image Luang Pho Phuttha Sothon, which draws huge crowds of Thai devotees every weekend. In recent years the province has also become known for the photogenic, somewhat surreal modern temple Wat Saman Rattanaram, with its enormous reclining pink Ganesha. Together they make Chachoengsao one of the most popular short religious-tourism getaways from the capital.

History runs deep here too — the city dates to the Ayutthaya period and retains a 19th-century fortress and city pillar shrine. Easy to reach by train, bus, or car, Chachoengsao rewards a relaxed day or overnight exploring temples, riverside markets, and old shophouse streets.

Chachoengsao is an inland, low-lying province with a tropical climate. The most comfortable time to visit is the cool, dry season from November to February, when temperatures are pleasant for temple visits and riverside markets. March to May is hot and humid, and the southwest monsoon (roughly May to October) brings frequent afternoon rain — the Bang Pakong plain can flood after heavy storms, though this rarely disrupts a short visit.

Because the province is primarily a day-trip and pilgrimage destination, weekends see the biggest crowds at Wat Sothon and Wat Saman, when the temple markets are at their liveliest — visit on a weekend for atmosphere, midweek for calm. The biggest religious event of the year is the Luang Pho Sothon fair, held twice annually (around the fifth lunar month, roughly April, and the twelfth lunar month, roughly November), filling the area around Wat Sothon with worshippers, processions, and fairground stalls.

Chachoengsao is unusually easy to reach from Bangkok. Trains run from Bangkok (Hua Lamphong / Krung Thep Aphiwat) to Chachoengsao Junction, a major rail node, with roughly a dozen services daily — the journey is cheap and scenic. Air-conditioned buses depart frequently from Mo Chit (Northern) and Ekamai (Eastern) terminals, taking about 1 hour 20 minutes via the motorway, and there is a first-class service direct from Suvarnabhumi Airport. By car it is 75–100 km depending on the route.

Within Chachoengsao town, the main local transport is the songthaew (shared covered pickup) and tuk-tuk. Songthaew lines are colour-coded — yellow links the train and bus stations along Sri Sothon Road; blue connects Wat Sothon with the city market — and fares are just a few baht. Tuk-tuks are honest and cheap, with basic fares around 30 baht and rarely more than 50 baht for in-town trips; having your destination written in Thai helps. Distances between the main sights — Wat Sothon, the city market, and the train station — are short. Wat Saman Rattanaram lies a little further out, best reached by tuk-tuk, taxi, or a hired songthaew.

• Chachoengsao town (Mueang Chachoengsao) — the riverside provincial capital and pilgrimage hub, with markets, old shophouses, and the city's main temples.
• Wat Sothon Wararam Worawihan — the province's spiritual centre, home of the revered Luang Pho Phuttha Sothon Buddha image.
• Wat Saman Rattanaram — a sprawling modern temple famous for its giant reclining pink Ganesha statue and "make merit" pavilions.
• Bang Khla — a riverside district known for its riverbank fruit orchards and the flying-fox (fruit bat) colony at Wat Pho Bang Khla.
• Khlong Suan 100-Year-Old Market — a century-old wooden waterside market on the Chachoengsao–Samut Prakan border, a nostalgic food-and-craft destination.
• Suan Somdet Phra Srinagarindra Park — a green lakeside park in the town centre, popular for walking and relaxing.

Chachoengsao's cuisine is shaped by its rivers and orchards. The province's historical signature is sun-dried giant snakehead fish (pla chon) — the very dish that gave Paet Rio its name — still sold dried and grilled at local markets. Freshwater fish, river prawns, and Bang Pakong seafood feature heavily in curries, soups, and grilled dishes.

The Bang Khla district is famed for its riverside fruit orchards, producing mango, mangosteen, and especially mango varieties; mango with sticky rice (khao niao mamuang) made with local fruit is a seasonal treat. Around Wat Sothon, a vast temporary market materialises each weekend morning, ideal for street food, snacks, and Thai sweets. For a memorable local meal, seek out the town's muu kratha (Thai BBQ-and-hotpot buffet) restaurants near Big C — around 200 baht per person for dinner. The Khlong Suan 100-Year-Old Market is a destination in itself for old-style noodles, grilled pork, and traditional sweets. Vegetarian food is available around the temples, especially during Buddhist festival periods.

Chachoengsao's identity is deeply tied to Buddhist faith and to the Bang Pakong River. Wat Sothon is the focus of the province's religious calendar; the Luang Pho Sothon fairs — held around the fifth and twelfth lunar months — are the biggest events, drawing pilgrims from across central Thailand for processions, merit-making, and a fairground atmosphere.

The province also has a notable Thai-Chinese heritage, reflected in shrine festivals and the riverside markets, and a strong scholarly legacy: the celebrated 19th-century educator and textbook author Phraya Sisunthonwohan (Noi Acharayangkun), who wrote foundational Thai-language primers, was a native of Paet Rio and is honoured with a monument in town. Local crafts include traditional wood-lace carving, sold near the popular Thursday afternoon market off the Wat Sothon road. The 19th-century Chachoengsao City Fortress and twin City Pillar Shrine (with pillars from the reigns of Rama III and Rama V) anchor the town's historical character.
