Trat to Tak Road Trip: Route 33 Guide

The Trat–Tak route follows National Highway 33 for roughly 540 kilometers, a road that partly traces a historical supply line used during the Ayutthaya period to move goods between the Gulf of Thailand and the interior. Driving the full length typically takes about 8 hours without stops, but the journey traverses three distinct provinces—Trat, Chanthaburi, and Tak—each with its own microclimates and topographies. This guide highlights the best stops Trat to Tak, with exact milestones and practical advice.

Drive west from Trat, and within 20 kilometers you hit the foothills of the Khao Soi Dao Wildlife Sanctuary, marking the transition from coastal plains to the evergreen forests of the Cardamom Mountains. The road then winds through fruit orchards and pepper farms before flattening into the central plains near Sa Kaeo. After Sa Kaeo, the terrain becomes more arid as you approach Tak's borderlands.

This article answers the common question: is it worth driving Trat to Tak? For most travelers, the answer is yes, but only if you plan to break the journey at a few key natural and cultural sites. The route is not simply a connection between two points; it offers waterfalls, national parks, and a UNESCO-listed temple complex that are often missed by those who rush.

The first major attraction is Nam Tok Khlong Na, a waterfall in Trat's Khlong Na sub-district, just 15 km from the town of Trat. The falls cascade over granite ledges into a swimming pool, a refreshing stop in the hot season. Further west, Khao Soi Dao Wildlife Sanctuary offers hiking trails and hotspots for birdwatching; its highest peak is nearly 1,675 meters.

Between Chanthaburi and Sa Kaeo, the landscape transitions into vast cassava and rubber plantations, with small roadside markets selling fresh fruit, especially durian and mangosteen in season (May–August). These markets are hubs of local commerce, and the trinkets and snacks reflect the region's blend of Thai and Khmer influences.

A must-see cultural landmark is Prasat Sdok Kok Thom, a Khmer temple complex from the 11th century, located near the Thai-Cambodian border, about 30 km south of Sa Kaeo. This UNESCO World Heritage Site (listed under Cambodia's inscription) is a rare example of an intact sandstone sanctuary, and it's often empty of tourists. To visit, you need to pass a Thai military checkpoint, but vehicles are waved through during daylight.

Beyond that, local commerce thrives in towns like Aranyaprathet, a border town with a bustling market that offers Cambodian goods. This is a glimpse into cross-border trade, but for most drivers, it's a quick photo opportunity and a chance to stretch legs.

Highway 33 has a moderately high accident rate due to speeding and frequent overtaking, so drive defensively. Weather extremes matter: during the hot season (March–May), temperatures can exceed 40°C, making asphalt soft and reducing tire grip. In the monsoon (June–October), flash floods can occur along low-lying sections near Sa Kaeo, so check forecasts. The cool season (November–February) is the most scenic, with green hills and cooler air, ideal for long drives.

For families, the route includes animal attractions like the Khao Kheow Open Zoo, located near the Sa Kaeo/Chonburi border, a 15 km detour. It's a drive-through zoo with elephants and giraffes, suitable for children. Another stop is the Trat Provincial Aquarium, a small facility with local marine life, perfect for a 30-minute visit.

Pets are welcome at most roadside restaurants with outdoor seating, but not inside national parks. Designated rest areas are located every 50 km, but they lack facilities—bring water and snacks. For fatigue, plan to stop every 2–3 hours; the best rest spots are at the Chanthaburi fruit market (Km 120) and the Sa Kaeo municipal park (Km 300).

Hidden off-route spots include the Ang Kha Roen hot springs, near the border in Chanthaburi, where locals say the mineral water relieves muscle aches. It's an unpaved road to the site, so take a high-clearance vehicle. Another secret gem is the Huay Luek Reservoir, between Sa Kaeo and Tak, with no facilities but serene views—bring a picnic.

Highway 33 is a two-lane road with occasional passing lanes, so traffic can slow behind heavy trucks, especially between Chanthaburi and Sa Kaeo. The road is sealed but not always in top condition, particularly after the rainy season when potholes may appear. Fuel stations appear regularly every 30–40 kilometers, but it's wise to fill up at larger towns like Chanthaburi or Prachinburi, where diesel prices average 32 THB per liter. Restrooms are available at most stations, but quality varies.

• Car rental: ~1,200 THB/day; tolls on Highway 7 (Bangkok bypass) if you detour.
• Estimated fuel cost for the entire route: about 1,500 THB for a typical sedan (12 km/l).
• No tolls on Highway 33 itself, but a small fee if you use the motorway briefly.

The route includes two significant mountain passes: the Khao Khitchakut climb near Chanthaburi and the Mae Usu Pass north of Tak. Both require careful driving in wet weather. For navigation, GPS coordinates are helpful: the midpoint at Sa Kaeo is at 13.824, 102.072. Local border checkpoints near Tak are rare but can add 10 minutes if you stray south toward Myanmar.

If you're wondering how long to drive Trat to Tak, the direct drive is 8 hours, but with an overnight stop (recommended at Chanthaburi's Nam Tok Philo area), the trip extends to 2 days. That's a comfortable split, allowing time for key stops.
