Pattaya to Nakhon Nayok: Road Trip Guide, Stops & Tips

Route 33 from Pattaya to Nakhon Nayok cuts across the lowlands of Chonburi and Chachoengsao, passing through Khao Khiao Massif's southern foothills. The highway is part of Thailand's eastern economic corridor, and it's a popular day-trip route for Bangkokians seeking waterfalls and cooler air.

This guide covers driving times, fuel costs, road conditions, family and pet-friendly stops, and hidden gems. For more on discovering offbeat spots, check how to find the best stops and hidden gems between cities.

The most direct path is via Route 36 east to Route 331 north, then merging onto Route 33. This is a well-paved, two-lane highway for most of the way, with occasional four-lane stretches near towns. Expect moderate traffic near Pattaya and lighter traffic after Ban Bueng.

• Distance: about 166 km, typically 2.5 hours without stops.
• Road quality: generally good, but watch for potholes in rural sections.
• Fuel: ample petrol stations along Route 331 and 33; prices are lower than in Pattaya city by about 1-2 baht per litre.
• Tolls: none on this route, but minor fees on some bridges (e.g., crossing the Bang Pakong River).
• Restrooms: available at most fuel stations and convenience stores.

The route transitions from palm-lined coastal plains to rolling hills covered with eucalyptus and rubber plantations. About 60 km from Pattaya, you'll pass Khao Khiao – not the famous zoo, but a scenic ridge that signals the start of higher terrain.

Locals trade in sugarcane and cassava; roadside stalls sell fresh produce and grilled chicken. The town of Phanom Sarakham is a good midpoint for a snack – try the local khao lam (sticky rice in bamboo).

Climate: Tropical savanna with a dry season from December to April. The rainy season (May-October) turns the hills lush but can cause landslides on minor roads.

Drive defensively, especially at intersections where rural locals sometimes ignore signals. Use high beams on unlit stretches at night, but dim when approaching other vehicles. Speed limits: 90 km/h on highways, 60 km/h in towns – beware of speed cameras.

For families, the Pattaya Elephant Jungle (just off Route 36) offers ethical elephant encounters, and Khao Khiao Open Zoo is a short detour with children's activities. Pets are welcome at many roadside restaurants with outdoor seating, but check individually.

Fatigue: Take breaks every 2 hours. The Phanom Sarakham Rest Stop (at km 88) has shaded picnic areas and a mini-market. If you need a quick nap, park at a petrol station with CCTV.
