3.3. By Flight

Flying from Phnom Penh to Sihanoukville can be done, though most trips require a stopover instead of going straight there. Routes often pass through Siem Reap or even Kuala Lumpur, which stretches travel time way beyond what the actual flying distance suggests. Depending on timing and where you switch planes, wait times might last anywhere from half a day to nearly a full one. That’s why people tend to pick these flights only if they’re already hopping between several cities or just don’t fancy lengthy bus rides.

Planes fly between Phnom Penh and Sihanoukville, though there aren’t many right now as service keeps shifting. You’ll find departures just a few days each week, meaning no steady routine you can count on every day. Airfare usually costs more compared to buses or cars, making it pricier for most people passing through. Since departure times jump around weekly, it’s smart to verify details ahead of time, particularly when catching a boat to Koh Rong afterward.

Recommended Stops Along the Way

Some folks like slipping in brief pauses during travel, particularly if they’re after something beyond the usual Phnom Penh highlights. These little detours bring fast bites of adventure on Route 4, turning a lengthy trip into an easier ride.

Kampong Speu Roadside Markets

These spots sell tropical fruits like mangoes, rambutans, and palm fruit that come straight from local farms, changing with the seasons. Stuff doesn’t cost much here, plus it’s way fresher compared to regular city markets. Along NR4, this place stands out because you can actually find working toilets and ice-cold drinks without hassle.

Kirirom National Park Gate Area

The entry zone is perched up high, bringing fresher breezes plus a clear change in what you see when coming from lower ground. Since lots of local families pass through on inter-province trips, weekends often bring spontaneous picnics alongside street sellers dishing out hot corn and sticky rice in bamboo tubes. Snapping scenic shots here works well, even if you’re skipping the official park gate.

Stung Hav Salt Fields

Near Sihanoukville, salt flats offer a unique sight you won’t forget. Tourists wander close to shallow pans where laborers scoop up salt under the hot sun. Pools shimmer brightly, great for pictures just after sunrise. A few tiny stalls trade rough-hewn sea salt taken straight from the ground; many passersby grab some, and it’s easy to carry home.

Phnom Sruoch Bat Caves

A quick side trip off NR4 takes you to limestone caves where bats live alongside tiny shrines.

Tips For Traveling From Phnom Penh To Sihanoukville

Folks heading from Phnom Penh to Sihanoukville usually take a few different legs; sorting out your schedule and path helps things go more easily.

Getting out of Phnom Penh at dawn makes sense when you’re aiming to grab a boat to Koh Rong or Koh Rong Samloem later that day.
A few days before, grab your bus or minivan spot on weekends or Khmer holidays, and pack this trip pack tightly. Pick early, avoid stress when rides get snapped up fast.
Sidestepping no-name vans booked via roadside sellers cuts danger – those rides usually speed up to stick to tight runs on Route 4.
Finding out precisely where you’ll get off in Sihanoukville ahead of time helps skip unnecessary moves, because certain rides halt a good distance from the boat dock.
Expect longer trips on Fridays around late afternoon or just before holidays, traffic heading out of Phnom Penh gets way busier then.
