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.

Phnom Penh to Sihanoukville: 7:30 a.m., 1:30 p.m.

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.

    Hi. Well I’ve booked a private taxi to go from Phnom Penh to Sihanoukville in December 13th. But I didn’t understand something. I’m traveling with two friends. And I’ve already paid the 60dollars. So, but are the 60dollars for all of us or each one should have bought his own ticket for a private taxi? Thanks in advance

    Roger says:

    does anybody know if there is a mini bus service between the PP Airport and Kampot.
    Many Thanks,

    Sergejs says:

    Giant Ibis picks up also from Phnom Penh airport , from River cafè, should be arranged in advance.
    By far not very luxurious ride and provides a number of points to direct complaints to, but overall is OK.
    Smart 4G along the route works impeccably vs. WiFi that was at best spotty.

    Don’t get a vehicle!!
    The road between Phnom Penh and Sihanoukville is the most dangerous road in the world!
    It’s one lane the whole way in horrible traffic.
    Car, busses and trucks are swerving in and out missing other vehicles by millimetres and overtaking literally in the OPPOSITE service lanes (gravel sidewalk) and most vehicles are dented and you’ll see at least 3-5 abandoned smashed up vehicles along the way. If you want a heart attack or don’t want to live then take a vehicle otherwise get a lovely smooth plane ride there that will stop at Siem Reap.
    Price is between $150-$200 and worth every cent!!!

      Michael – I’ve been coming to my Cambodian PP family for almost 15 years, and 3/4 times a year we spend a few days on the coast (S’ville etc) Have always gone by a full-size bus and never had any problems or anxieties. This year will be our last at the building site S’ville has become, as we feel the heart is being ripped out in favour of identikit tower block hotels. Sorry to see so many small if scruffy places closed.

    Hi Lina

    Thank you for your article.

    My partner and I are staying in Kampong Speu. We are hoping to spend this weekend in Sihanoukville.

    What is the best way for us to get to Sihanoukville directly from Kampong Speu? We would like to leave on Saturday morning as early as possible – and return on Monday morning as early as possible.

    Thanks very much for your assistance.

    Giant Ibis DOES NOT drop off at hotels in Sihanoukville. They were really rude at the PP office when they looked incredulously at me for asking to do so. I think they know they are the preferred company amongst expats and are getting cocky! Also they supply stale Blue Pumpkin pastries which are flattened in black garbage bags.

      Lina says:

      I don’t think anyone suggested that Giant Ibis drop off at hotels in Sihanoukville, like almost all bus companies in Cambodia they do hotel pick-up only.
