How to Get from Phnom Penh to Siem Reap: Bus, Flight, or Ferry for Americans

为什么这条路线对您2026年的柬埔寨之旅很重要

金边和暹粒几乎是每个美国旅客柬埔寨之行的两个核心目的地。您在首都着陆，您想站在吴哥窟前看日出，而这两地之间195英里是塑造您整个行程的唯一一个物流决策。做对了，您精神饱满地抵达，还多出一整天的时间；做错了，您浪费了半天本想用于吴哥窟的时间。

2026年的好消息是这条路线从未如此便捷。金边-暹粒高速公路将巴士行程缩短为稳定的6小时，两城之间的国内航线已恢复每日多班航班，雨季穿越洞里萨河的渡轮仍在运营，为想要慢节奏、风景优美的旅客提供了选择。三种方式在时间、费用和景色上权衡分明，没有错误的答案——只有适合您旅行的那个。

本指南详细分析了这三种方式的真实美元费用、实际旅行时间以及初次访客容易忽略的细节——然后将其与您在任何行程之前必须处理的一件事情联系起来：您的柬埔寨签证。如果您还在规划整个行程，我们的10天柬埔寨行程（美国旅客专版）会将这段行程整合到完整路线中，一旦您的日期确定，您可以立即申请eVisa。

Express bus: cheapest and the local default

The bus is what most Cambodians take and what most budget-minded American travelers should take too. Since the expressway opened, the express coaches run a steady 6 hours city-center to city-center, and the fare sits between $12 and $18 USD depending on the operator and how nice the seat is. Departures are roughly hourly through the day from the bus offices clustered around central Phnom Penh, plus a few overnight sleeper runs.

What you actually get for the price

The mainstream operators — Giant Ibis, Mekong Express, and Vireak Buntham among them — run air-conditioned coaches with assigned seats, USB charging, Wi-Fi that works about half the time, a bottle of water, and a snack. The premium operators are worth the extra two or three dollars for the legroom alone if you are tall; American knees and the standard local seat pitch do not always agree. Sleeper buses with flat-ish berths run overnight and save you a hotel night, though light sleepers tend to regret them.

Book a day or two ahead in the high season (November to February) and you can walk on the rest of the year. Most operators let you reserve online and pay by card, or you pay cash in USD at the office. Bring your passport — you will not be asked for a visa on a domestic leg, but the booking name should match your ID, and the bus offices double as drop-off points for the hotel pickup vans.

The domestic flight: fastest, lands at SAI

If your trip is short or you have a 4:30 a.m. Angkor sunrise on the schedule, fly. The hop between Phnom Penh and Siem Reap is 45 minutes in the air, and Cambodia Angkor Air and a couple of regional carriers run several flights a day. One-way fares land between $60 and $90 USD when you book ahead, climbing toward $120 USD if you buy on the day in peak season. Round it up to about 2.5 hours door-to-door once you factor in getting to the airport, check-in, and the transfer at the far end.
