Introduction
The border crossing at Ban Laem/Daun Lem is the shortest international link between Thailand and Cambodia, and the 160-kilometer drive from Chanthaburi to Samraong takes roughly three hours by car under normal conditions.
This route follows National Highway 3 south through rubber plantations and tropical fruit orchards before turning east on the 33 toward Pailin. The area's gemstone history is evident in roadside stalls, but the real draw is the transition from Thai coastal plains to Cambodian lowlands.
| Segment | Distance | Time |
|---|---|---|
| Chanthaburi to Pailin | 110 km | 2h 10m |
| Pailin to Samraong | 50 km | 50m |

A 20-kilometer detour on Route 3220 leads to the Krathing Waterfall, a local swimming spot. In Pailin, former Khmer Rouge commanders run a small museum about the region's conflict.

Road Safety, Family Stops, and Fatigue Management
Family and Pet-Friendly Framework
Several fruit farms along the Thai side (like the Suan Lam Duen orchard) offer family-friendly tours. Pets are permitted at roadside picnic areas, and Cambodia requires a rabies vaccination certificate for entry.
Rest Zones and Dining
Plan a break at Pong Nam Ron, the last Thai town before the border, where a 24-hour petrol station has clean restrooms. For food, the local markets in Pailin serve Cambodian-style noodles and grilled meats.
