By Motorcycle
It is a 230 km, 4-5 hour trip on Route #4. Most cyclists rent 250cc off-road bikes for the trip. Rent motorcycles at Lucky Lucky or New New Motorcycle on Monivong, near Street 184 in Phnom Penh. Leaving Phnom Penh, follow Confederation de la Russie (Airport Road) south past the airport and out of town. At the Route #3/#4 fork roundabout just east of Phnom Penh (Chom Chao), bear right. National Route #4 to Sihanoukville is paved and smooth, fast, easy, and a relatively dangerous road: speeding taxis and reckless lorries are the norm. Slow down through the villages, watch for errant animals and oblivious children. Wear a helmet and bear in mind that medical help and rescueis a long way away in the countryside. Stop for a refreshment break at one of the many road side stands at Pich Nil near the half-way point.
