I’ve tried just about every way of getting from Phnom Penh to Siem Reap — from flights to minibuses, trains, and even (almost) boats. I’ve tested routes through the new and old airports, sat on buses for hours, and learned which rides are worth the hype… and which definitely aren’t.
And honestly?
If I have the time, I’ll always choose the bus.
Here’s why — and how each option compares, depending on your budget, time, and travel style.
1. Flights from Phnom Penh to Siem Reap
Flying sounds like the fastest way, but in Cambodia, it’s not as simple as it seems.
The old Phnom Penh airport was already a bit far from the city, but the new Techo International Airport is even further — depending on traffic and transport, it’s about 40–90 minutes away.
We took a tuktuk via Grab for $6 (headed to the airport), which felt reasonable. When we arrived, we realized that the airport wasn’t exactly what we expected. There were barely any facilities. No clear ATMs, and only one employee running two small “cafés” in domestic departures. I know it’s a brand-new airport (at the time of writing), so hopefully it’ll improve soon.
The flight itself? Super quick — 30–35 minutes in the air. I barely finished my complimentary cookie before we started descending. But once you land, Siem Reap’s airport is actually an hour and twenty minutes from the city, and that car ride costs another $20 each way.
When I added it all up, the trip took about 5.5 hours door-to-door (this includes check-in time, which wasn’t even the full 2 hours) and cost me $180, even with discounted flights.
Verdict: Super quick in the air, but with all the waiting, check-ins, and transfers, it’s not really time-efficient and definitely not budget-friendly.
2. Book a Bus Between Phnom Penh to Siem Reap
This is my favorite way to travel between Phnom Penh and Siem Reap. It’s reliable, affordable, and straightforward.
The journey takes around 7–8 hours, and tickets range from $10–30, depending on the company and comfort level. For budget travelers, it’s a no-brainer: you save a lot of money, and it only takes about 1.5–2.5 hours longer than flying.
We’ve tried several minibus companies, but honestly, I never feel totally safe in them. They’re fine and tons of people use them daily, but I personally prefer the big buses.
My go-to is Giant Ibis. Yes, they’re pricier, but totally worth it:
✅ Air-conditioning
✅ Wi-Fi
✅ Snack and water included
✅ Professional drivers and attendants
It’s a comfortable, safe, and easy ride. We’ve even used Giant Ibis for trips to Ho Chi Minh City!
Verdict: The best balance between comfort, cost, and convenience. It’s my top choice every time.
3. Trains Between Siem Reap & Phnom Penh (Kind Of)
There’s no direct train from Phnom Penh to Siem Reap.
But you can take a train from Phnom Penh to Battambang on the northern line. Tickets are under $10 per person, and on weekends, you can even bring your motorcycle along.
Just be warned: service for motorcylce transfers can be inconsistent. Even when they confirm your booking, they’ve been known to cancel trips at the last minute (we’ve had this happen and had to drive all the way back to Phnom Penh).
Once in Battambang, it’s about a 3-hour drive to Siem Reap. You can ride your own motorbike or catch a bus/minibus from there.
Verdict: Great for adventurers or those who want to explore Battambang along the way, but not ideal for direct travel.
4. Hire a Private Car
A private car is a popular (and comfortable) option, especially if you’re traveling as a group of 3–4 people. It’s obviously more expensive for solo travelers or couples, but totally worth it if you can split the cost.
There are lots of reliable drivers offering this route. The best way to find them is by checking Facebook travel groups for Cambodia. You don’t even need to ask; just search “Phnom Penh to Siem Reap driver” and you’ll find tons of recommendations already posted.
Prices vary from $80–$300, depending on the car, driver, season, and number of passengers. With a little research, you can find something very comfortable and trustworthy.
Verdict: The fastest and most comfortable way for small groups — especially if you value convenience and privacy.
5. Travel by Boat
Now here’s one I haven’t tried yet, but I really want to!
There are a few companies offering boat trips from Phnom Penh to Siem Reap along the Tonle Sap River. It’s not a mainstream option (which is why it’s so hard to find info), but it sounds incredible.
From what I’ve seen, basic packages cost about $140 and take a full day (half boat, half bus ride), while some companies offer overnight trips for around $240. It’s a scenic, slow way to travel, and I’ll definitely update this post once I’ve done it myself.
Verdict: For slow travelers and adventure lovers who want to see Cambodia from a completely new perspective.
Final Thoughts: My Favorite Way to Travel
I’ve tried planes, buses, and even planned a train-and-bike combo once — but for me, the bus wins every time.
It’s affordable, safe, comfortable, and honestly… not that much slower once you add up all the airport time. The journey’s scenic, the snacks are free, and there’s something nice about sitting back, listening to music, and watching the Cambodian countryside roll by.
That said, everyone’s travel style is different, so I’d love to hear from you!
