Kampot to Sihanoukville Road Trip: A Practical Guide

The drive from Kampot to Sihanoukville spans 108 km (67 miles) along National Highway 4 (NH4), a route that cuts through the Cambodian coastal belt. This road, initially built in the 1960s and upgraded in the 2000s, connects the sleepy riverside town of Kampot with Cambodia's busiest port city. The highway's curves follow the contours of the Elephant Mountains, offering drivers a mix of coastal and mountain scenery. One notable driving quirk: the road passes through several small towns where livestock and pedestrians share the asphalt, requiring heightened alertness.
