Sihanoukville taxi

One of our favorite Sihanoukville taxi drivers.


Private taxis are the fastest way to get from Phnom Penh to Sihanoukville, and usually cost between $50 and $60. In high season the prices can climb even higher. Taxis can seat four people, but be warned that they don’t usually have enough room for a ton of luggage. Most of the taxis that go between Phnom Penh and Sihanoukville are Camrys, and the drivers aren’t afraid to hit the gas. Expect to get there in around 4 hours or less, although we’d advise you to keep your eyes closed. Later departures will take longer due to traffic.

You can book a taxi online in advance, and the prices are surprisingly reasonable. In fact, if you book online you can get an SUV taxi that seats five for the same price around $60. There is also the option to book a 7- or 10-seat minivan.

We also have a few taxi recommendations in our Sihanoukville City Guide, but they will need to be booked a day in advance.

Buses, mini-buses, and express vans

Most companies running the full-size buses that go between Phnom Penh and Sihanoukville are objectively terrible: unsafe, slow, and uncomfortable. The shining exception is Giant Ibis. But a faster, more comfortable way to go between Phnom Penh and Sihanoukville, is by mini-bus or “VIP van.” The trip takes between 4 and 6 hours for vans and minibuses, and up to 7 hours for full-size buses, depending on traffic getting in and out of Phnom Penh.

Giant Ibis

Foreigner favorite bus company Giant Ibis has started running full size, 38-seat buses on the Phnom Penh to Sihanoukville route in 2019. They are noticeably better than most Cambodian bus companies, and offer seat belts, relatively safe drivers, WiFi that works occasionally and a TV that plays English-language movies. The best part is they don’t stop dozens of times to pick up and drop off passengers and always leave on time. The bus stops once along the way for snacks and a bathroom break. Tickets cost $15 and include hotel pickup.

You can book Giant Ibis tickets online in advance, which allows you to pick and reserve a seat for less than $1. Buses drop off and pick up at the Giant Ibis office and the trip takes about 6 hours.

Cambodia Post Phnom Penh to Sihanoukville

The Cambodia Post van takes bags of mail, and you, between Phnom Penh and Sihanoukville.

Cambodia Post VIP Van

The Cambodia postal service runs passenger vans between many major cities in Cambodia (don’t be surprised to see bags of mail in the back). Cambodia Post vans are great value for money, so it’s all the more surprising what a pleasant journey they offer. Drivers are safe and courteous and when the network permits it, there is WiFi on the van. Be aware that the front middle seat (A1) is extremely cramped. Tickets cost $8 per person and can be purchased online in advance for a small fee, which allows seats to be reserved in advance. They often sell out, so book early.

Mekong Express

Mekong Express used to run a decrepit fleet of old Japanese buses between Phnom Penh and Sihanoukville, and before Giant Ibis came on the scene, they were the expat favorite. They’ve abandoned the buses and are now running “VIP Vans” decorated with decals of prancing horses. They have a good safety record and are known to drive at reasonable speeds. They have a two-tiered pricing policy; Khmers pay $10 and foreigners pay $12. You can book tickets online in advance (so you can reserve the best seat) for less than $1.

Mekong Express schedule
Phnom Penh to Sihanoukville: 7 a.m., 8 a.m., 8:30 a.m., 9:30 a.m., 12:30 p.m., 1:30 p.m., 3 p.m., 5:30 p.m.
Sihanoukville to Phnom Penh: 7 a.m., 8 a.m., 8:30 a.m., 9:30 a.m., 12:30 p.m., 1:30 p.m., 3 p.m., 5:30 p.m.

Shared taxi

Shared taxis are usually 5-seater Camrys that somehow manage to hold seven passengers plus the driver. You can get shared taxis from the southwest corner of Central Market (Psar Thmei) in Phnom Penh or at the old bus station in Sihanoukville. Seats cost around $7-10 per person. You can offer to pay extra to take the front seat, otherwise you’ll be squeezed in with three or four others in the backseat. The journey take between 3 and 3.5 hours because they drive fast.


Cambodia has recently restarted their train service, and on weekends you can take the train from Phnom Penh to Sihanoukville. The trip takes about 7 hours. Learn more in our post about taking the train in Cambodia.

Going from the Phnom Penh airport to Sihanoukville

If you’d like to go from the Phnom Penh airport straight to Sihanoukville, you have a few options. The easiest is to book a taxi online, in advance. The cost is $65 for an SUV taxi, and the driver will wait for you outside with a sign and help you with your bags.

You can also take an official airport taxi, or catch a taxi outside for between $60 and $80, but you will need to negotiate. Another option is to arrange for any of the bus companies listed above to pick you up at the Park Cafe directly across from the airport. This much be arranged in advance and they will pick you up 50-60 minutes from the scheduled time of departure.

    Adam says:

    What about the train?! There’s little to no info on this weekend option.

      Tammy says:

      We enquired recently and found there is no longer a train service running.
      The Giant Ibis buses are great, comfortable, A/C, not reliable WiFi though.
      The pitstops halfway is well needed for toilet and food break. 20 min break.

    Linds says:

    Can you find a taxi to Sihanoukville at the airport? I’ve only come the opposite way ( and it took us 5 hours!) what time do you think is best to avoid traffic getting out of the city? Thanks!!

    Marek says:

    Not all taxis drive fast, and buses take way more than 5 hours, the information here is incorrect. All trips I’ve taken have been around 6 hours, the one I took in a taxi was 5.

    Hi folks,
    To anyone reading this; I paid $60 usd for a taxi to sihanoukville. This was at midnight and I didn’t bother t haggle. You can probably get it for $50. It was a Toyota Camry all to myself. I could sleep on the back seat. The return was cheaper. $45 back to PP. I highly recommend it as your on your schedule and can stop as you please. The trip took about 3h each way. Enjoy Sihanoukville

    eric says:

    Hi guys, I land in PP tomorrow at 11pm (quite late). I don’t plan on booking a taxi ahead of time. I realize that the cost may be more than the ~$60 usd mentioned on this page. Two questions: 1) how much do you think it will cost me and 2) should I have usd ready to pay or should I have local currency? Thanks, Eric

    Peter says:
