Kep to Kampong Chhnang Drive: Essential Guide

The route from Kep to Kampong Chhnang traces the path of National Highway 3 northward, a journey that cuts through the heart of Cambodia's southern agricultural belt. As you leave Kep National Park's limestone outcrops behind, the road unfurls over a distance of approximately 230 kilometers, a drive that typically takes between 5 and 6 hours depending on traffic and road conditions.

This guide covers essential logistics, natural attractions, and practical tips for families and pet owners, ensuring you're well-prepared for the journey.

As NR3 climbs away from the coast, the landscape transitions from flat paddy fields to the foothills of the Cardamom Mountains. One of the most visually striking sections is the climb towards Kirirom National Park, where pine forests contrast sharply with the tropical surroundings. The park itself, a hill station established in 1993, offers hiking trails and waterfalls, making it a worthwhile detour.

The route passes through several markets where you can sample local produce, including Kampot's famous pepper, which is often sold in roadside stalls. In the town of Skuon, a bustling junction known for its deep-fried spiders, the local commerce reflects a unique culinary tradition.

UNESCO World Heritage Sites are not directly on this route, but the famed Angkor Wat lies far to the north, making Kep and Kampong Chhnang more accessible gateways to Cambodia's history. However, the town of Oudong, about 40 km above Kampong Chhnang, is a former royal capital with significant pagodas and stupas, and is a potential day trip from there.

The drive begins in Kep, a coastal town known for its crab market, and heads north on NR3, passing through Kampot, then veering northwest towards National Highway 5 in the vicinity of Skuon. The road quality varies: the segment from Kep to Kampot is well-paved but narrow, while beyond Kampot, the road improves to a smooth two-lane highway with occasional passing lanes.

Fuel stations are sparse outside major towns, so it's advisable to fill up in Kampot, about 25 km from Kep. The route passes through several small towns, such as Kirirom National Park's eastern edge, offering opportunities to stop for refreshments.

For those wondering how to find the best stops and hidden gems between cities, this highway offers a mix of well-known landmarks and lesser-explored spots. The journey's length can be broken into two segments with an overnight in Kampong Speu or Kirirom, if desired.

Road safety on NR3 has improved in recent years, but caution is still needed. In rural areas, livestock and motorbikes may appear unexpectedly. Night driving is not recommended due to limited lighting and the presence of large trucks on the highway.

For families, there are several child-friendly stops along the way. Kirirom National Park offers picnic areas and easy trails, while the Kirirom Resort provides a safe play area. At about halfway, the town of Kampong Speu has a water park with slides, popular with local families.

Fatigue management is crucial on a drive of this length. The route includes several designated rest areas with shaded benches, but these may lack facilities. A better option is to plan a lunch stop in Kampong Speu, where you'll find numerous restaurants with air conditioning. Neither accommodation nor restaurants along the route are typically pet-friendly, so pet owners should plan to keep pets in the car and pack food, as dining options may not welcome animals.
