Uttaradit to Chon Buri: A Practical Road Trip Guide

The route from Uttaradit to Chon Buri covers roughly 550 kilometers via Highway 11 and 1, then east on 304, and finally south on 7. This journey typically takes 7 to 8 hours of driving time, depending on traffic and stops. As you leave Uttaradit, you'll notice the landscape shift from the lush, mountainous terrain of the north to the flatter, agricultural plains of the central region. The route crosses several significant rivers, including the Nan and the Chao Phraya, before reaching the industrial and coastal province of Chon Buri.

For an overview of how to plan an optimized trip, check how to find the best stops and hidden gems between cities.

Road quality is high, but watch for speeding trucks and sudden lane changes, especially in construction zones. Ensure your car is in good condition, and keep a first-aid kit handy.

For families, suitable rest areas include the PTT station in Phitsanulok, which has a playground, and the café at Khao Kho viewpoint.

To manage fatigue, plan a break every 2 hours or 150 kilometers. Combine stops with meals or fuel. The longest stretch without a major town is between Saraburi and Nakhon Ratchasima, so plan accordingly.

• Recommended lunch stop: Nakhon Sawan, known for its boat noodles.
• Pet-friendly stops are limited; most stations do not allow pets inside, but there are grassy areas to walk them. Some hotels in Chon Buri are pet-friendly, but confirm in advance.

The northern section of the trip passes near Khao Kho, known for its cool climate and scenic viewpoints. The central plains are dominated by rice paddies and sunflower fields, especially around Saraburi in winter. As you approach Chon Buri, the land becomes more industrial, but the coast offers a contrast with its sandy beaches like Bang Saen.

Local markets along the way, such as the one in Sukhothai, sell regional snacks and handicrafts. The area around Lopburi is famous for its sunflowers and macaques.

For UNESCO World Heritage Sites, consider a small detour west to Sukhothai Historical Park, about 60 km off the main route. This site boasts ruins from the 13th-century Sukhothai Kingdom and is well worth a few hours. Another optional stop is the ancient city of Ayutthaya, though it's further from the highway.

Chon Buri itself is known for its seafood markets, particularly in the fishing village of Bang Saen, and for the Khao Khiao open zoo.

Highway conditions are generally good, with well-paved surfaces and clear signage. Tolls apply on parts of Highway 7 near Bangkok and Chon Buri, so carry cash or a toll card. Fuel stations are plentiful every 50-100 km along the route, with major brands like PTT and Caltex offering restrooms and convenience stores.

• Estimated fuel cost: ~1,200-1,500 THB for a standard sedan.
• Recommended rest stops: Phitsanulok (large PTT station), Nakhon Sawan (rest area with food court), Saraburi (after the mountain pass).
• No direct tolls until the final stretch; plan for a total of 300-400 THB in tolls.

Driving at night is possible, but be cautious of wildlife in rural areas near national parks. The road passes through several provincial capitals, allowing easy access to hospitals and services if needed. For a stress-free journey, start early morning to avoid Bangkok's traffic congestion, which typically peaks after 3 PM.

Parking in Chon Buri is readily available, with most hotels offering free parking. If heading to Pattaya, expect more crowded streets.
