One of our favorite Sihanoukville taxi drivers.
Taxi
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.

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

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.
Train
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.

Is it possible to take a boat to Sihanoukville from P.P or Siem Reap?
Nope.
Hi, I will be flying into PP late January and I want to go directly to Sihanoukville. Can you recommend a reliable safe private taxi for me ? One person.
And the normal price too please.
Thanking you in advance.
Your guesthouse in Sihanoukville can arrange it for you, price from the airport will be $5 to $10 more than from Phnom Penh city center.
Hi great info thanks, I’m trying to get from PP to Sihanoukville from PP airport as want to avoid the trip into the city only to have to leave again – i arrive at 1pm, is this possible without forking out for a private taxi – are there shared ones going from there?
No shared taxis going from the airport, but you could take a tuk tuk into town and get a shared taxi or bus from there.
I’ll be arriving at PP airport at 8.30am on 24th Dec and want to go straight to Sihanoukville as quickly as possible, do you know if any of the minibuses go from the airport?
Not that I know of.
Hi Lina, thank you for the awesome info! I am wondering if I arrive in Phnom Phen at 10:20pm, do you think I will be able to find a taxi? Thank you so much for your help!!
Yes, there are taxis waiting for all of the incoming flights. Have a nice trip. :)
I’ve just got a really bad experience with Giant Ibis!
I’ve choose Giant Ibis because of its respectable reputation that I’ve seen from many reviews on internet…Even tough the price was a bit higher than other companies, I thought It would worth.
I bought my tickets from Phnom Penh to Sihanoukvile 2 days in advance so I thought I wouldn’t have any problem. I was wrong…
The bus would leave PP at 9:30 am so they told me they would pick me up at 8:30 in my hotel.
I woke up at 7:30, so then I could be punctual. I had my breakfast and went to the hall to wait for the transfer. When it was 8:45 I called them to ask if everything was fine and they said that the van was on the way to pick me!
In total I waited them for more than 1 hour, and then when it was 9:45 am, aka 15 minutes after the bus was supposed to leave the terminal, they called me saying that I should go to the terminal by myself and the expense with tuktuk would be on me, the explanation was that the government didn’t allow them to pick me up (seriously?). However, when I got there all the passengers were already there, which means I was the only one that they didn’t pick up. they didn’t say sorry at all! It may happens frequently…
When I got there all the passengers were looking at me as I was guilty for them being late.
All at all, avoid this company, you pay more because of its reliability but you don’t get it back. I spent twice the price I would pay if I had chosen other transport companies.
Sorry for your bad experience. I travel in cambodia every year and catch giant ibis. Regularly I wouldn’t travel on any other bus company they are the safest over there. I have been on many others. Never had a problem
