Pattaya to Pak Chong: Essential Drive Guide

The highway 331 north from Pattaya to Pak Chong skirts the western edge of Khao Yai National Park, a route first carved through elephant corridors in the 1960s. This 200-kilometer drive typically takes 3.5 to 4 hours, with the final ascent toward the Khao Yai plateau offering a 500-meter elevation gain that drops temperatures noticeably.

Road quality is good, but watch for wildlife crossings — wild elephants often roam near Khao Yai. Drive slowly through dusk and dawn, and obey speed limits (80-100 km/h). Use designated rest areas every hour; the most popular is the PTT rest stop at km marker 120, with clean toilets and a small café.

• Family-ready stops: the Khao Yai Art Museum in Pak Chong, with interactive exhibits, and Farm Chokchai dairy farm, offering petting zoo and tractor tours.
• Pet-friendly: many roadside restaurants with outdoor seating allow leashed pets, but national park trails do not.
• For fatigue, pull into any 7-Eleven — found every 15 km near towns — for coffee and a quick nap in a shaded spot.

Culinary infrastructure includes local diners serving som tam and grilled chicken. For hidden off-route spots, detour 20 km south of Kabin Buri to the Wang Takrai waterfalls, a local picnic favorite. Climatically, expect 30°C (86°F) in Pattaya rising to 35°C (95°F) in the lowlands, dropping to 25°C (77°F) in Pak Chong — a welcome change.

Rolling farmland gives way to dense dry evergreen forest as you near Khao Yai — a UNESCO World Heritage Site since 2005, part of the Dong Phayayen-Khao Yai forest complex. Stop at the Khao Yai National Park visitor center for trail maps, or simply enjoy views from the road shoulder.

The route passes through Kabin Buri, known for its fruit orchards — durian season runs June to August. Local commerce thrives in roadside stalls selling fresh pomelo, mango, and coconut juice. In Pak Chong, the weekend Talat Tai market offers local handicrafts and coffee from highland plantations.

The primary artery is Highway 331, which transitions to Highway 33 at Kabin Buri, then onto Highway 304 for the final leg. Well-maintained, with multiple lanes through Chonburi and smoother two-lane sections near Khao Yai, road quality is high, though potholes appear after heavy rains.

• Fuel stops abundant every 20-30 km on Highway 331; PTT stations offer 91/95 gasoline and diesel.
• Expect tolls only on the motorway out of Pattaya — about 100 THB.
• Drive time can extend by 30 minutes during weekends due to resort traffic.

For breakdowns, the Highway Police hotline 1193 works. Pak Chong town has several 24-hour garages, but rural stretches lack mobile signal — consider a paper map. The how to find the best stops and hidden gems between cities method applies: scan for brown signs indicating scenic viewpoints.
