Chachoengsao–Prachinburi
Temples + Nature, 2 Days

🔄 Updated 21 Jun 2026

A lot of people come to Paet Riu to pray at Luang Pho Sothon on a day trip and still feel like they haven't seen enough — when driving just a little farther gets you to Prachinburi, a province with a completely different set of attractions. There's the Sri Maha Bodhi tree, believed to be the oldest in Thailand; Wat Kaeo Phichit, which blends Thai, Chinese, and European art in one place; the yellow Baroque-style Chao Phraya Abhaibhubejhr building; and lush green scenery, since the town sits on the edge of the Dong Phaya Yen–Khao Yai forest.

So we've put it together as a 2-day, 1-night trip to make the fuel and time worth it. Day one covers Paet Riu's temple highlights in full, with one night's stay; day two crosses into Prachin and loops back. Before the detailed plan, let's get the route and prep clear first, because this trip is easiest done by car.

Route and getting there

From Bangkok to Chachoengsao, take Motorway 7 or Route 304 (Bangkok–Min Buri–Chachoengsao), about 1 to 1.5 hours. From Chachoengsao town up to Prachinburi town, take Route 319 then 304, roughly 75–90 km, about an hour and a half. The road alternates between two and four lanes and drives easily, with gas stations and restaurants along the way. We recommend driving yourself or renting a car for this trip, because the sights in Prachin are spread out and public transport between districts doesn't run often.

• Bangkok → Chachoengsao — Motorway 7 or Route 304, about 1–1.5 hours. Head straight into town for Wat Sothon.
• Chachoengsao → Prachinburi — Route 319 then 304, about 75–90 km, around an hour and a half, passing through Bang Khla and Si Maha Phot districts.
• Public transport — There are vans and buses from Bangkok to Prachin, and the Eastern Line railway passes through both provinces, but Prachin's sights are scattered, so driving yourself is far more convenient.
• Fuel/tolls — Budget for round-trip fuel and motorway tolls. This loop totals roughly 250–300 km.

Day 1 — Paet Riu temple run, two famous wats

Day one covers Chachoengsao's temple highlights in full. Start at Luang Pho Sothon, the province's most revered Buddha, then on to Wat Saman Rattanaram with its huge reclining pink Ganesha, and close the day with markets and riverside food along the Bang Pakong River.

Day 2 — Cross into Prachinburi: temples + nature

On the morning of day two, drive up to Prachinburi. This town stands out for its heritage and nature: the Sri Maha Bodhi tree believed to be the oldest in Thailand, Wat Kaeo Phichit with its mix of architectural styles, the yellow Chao Phraya Abhaibhubejhr building that's now a herbal museum, and cool, pleasant air thanks to the town sitting on the edge of the Dong Phaya Yen forest.

Two provinces' food you shouldn't miss

On a cross-province trip like this, the food is different in each place too. Paet Riu shines with local dishes and souvenirs, while Prachin is strong on herbs and riverside food. Save room in your stomach.

Before you set off

• Dress modestly — Wat Sothon, Wat Saman, Wat Kaeo Phichit, and the Bodhi tree are all sacred sites. Wear sleeved tops and pants or knee-length skirts.
• Bring cash — Offerings, parking, and many small market stalls take cash; keep some small bills handy.
• Check opening hours — The museum and the Abhaibhubejhr building have their own closing days and hours; check before you go so you don't make a wasted trip.
• Plan your order well — Prachin's sights span several districts, so routing from nearest to farthest saves time and fuel.
• Pack an umbrella/hat — The sun is strong while walking temples and outdoors, especially in the hot season; in the rainy season, bring an umbrella in case of rain too.
