A 7-Day Cambodia Itinerary for Americans Short on Time

Day 4: getting from Siem Reap to Phnom Penh

The two cities are about 300 kilometers apart, and how you cover that gap shapes your whole day. There are three sensible ways to do it, and the right one depends on whether you are protecting time or budget.

The fastest is a domestic flight — roughly 45 minutes in the air, and it turns a travel day into a half-day, leaving you an afternoon in Phnom Penh. It is the priciest option but, on a one-week trip where every hour counts, often the smartest. The cheapest and most popular is the express bus or minivan: comfortable air-conditioned coaches run the route in about six hours, usually leaving mid-morning and arriving late afternoon. A private car or taxi sits in between on price, gives you door-to-door flexibility and a stop or two along the way, and takes a similar five to six hours.

Whichever you choose, book the link a few days ahead in peak season — flights sell out and the best bus times fill up. Our full breakdown of getting from Phnom Penh to Siem Reap and back lays out current prices, journey times, and which operators are worth booking, so you can lock the middle of your week before you land.

A practical note for a tight week: if you fly, you can keep day four almost intact — temples in the Siem Reap morning, a midday flight, and the Royal Palace or a riverfront dinner that same evening in Phnom Penh. If you take the bus, treat day four as a true transit day and start Phnom Penh fresh on day five. Plan it the way it actually falls rather than hoping to do both.

Days 5-7: Phnom Penh, history, and the riverfront

Phnom Penh is a different trip from Siem Reap — a real, busy capital on the confluence of the Mekong and Tonle Sap rivers, with a heavier, more recent history. Two full days plus a departure morning is the right amount. It is enough to cover the essential sights, sit with the harder ones, and still get a feel for the city over a riverside dinner.

Day 5 — Royal Palace, National Museum, riverfront

Start at the Royal Palace and the Silver Pagoda, ideally in the morning before the heat peaks (note the lunchtime closure and the dress code — covered shoulders and knees). Walk a few minutes to the National Museum, which holds the finest collection of Khmer sculpture anywhere, and gives the Angkor temples you just saw a deeper context. In the late afternoon, the riverfront promenade along Sisowath Quay comes alive — a sundowner over the Tonle Sap is the classic first evening in the capital.

Day 6 — Tuol Sleng and Choeung Ek

Day six is the hard, important one. The Tuol Sleng Genocide Museum, a former school turned prison, and the Choeung Ek memorial — the best known of the killing fields — together tell the story of the Khmer Rouge years. The audio guides are excellent and humane. It is heavy, and most visitors find half a day is right, leaving the afternoon for something gentler: Wat Phnom, the Central Market dome, or the cafes and shops around the Bassac area. Be kind to yourself with the pacing here.

Day 7 — last morning and the flight home

Your last day depends on your flight. International departures now leave from KTI Techo International, the new airport that replaced the old Phnom Penh airport in September 2025, so allow a little extra time to reach it and to clear an unfamiliar terminal. If you have a morning free, the Russian Market is the best spot for last-minute gifts and a final iced coffee, and a quick loop of the riverfront makes a fitting goodbye before you head to the airport.

ویزا اور آمد کارڈ جس کی آپ کو ان میں سے کسی بھی چیز سے پہلے ضرورت ہے

A perfect itinerary is worthless if you cannot board the plane. Americans need a visa for Cambodia, and the easiest route by far is the eVisa, sorted online before you leave home. A Tourist eVisa is $80 USD all-in, approved in 3–5 days, valid for 3 months from the date it is issued, and gives you a 30-day single-entry stay — far more than a one-week trip needs. It arrives as a printable PDF by email; print it, pack it, and you are set for immigration.

Two timing details matter for a tight trip. First, the tourist auto-extension ended in November 2025, so the 30-day stay is now a firm ceiling — not a problem for seven days, but worth knowing. Second, the eVisa is only half the entry paperwork. The Cambodia e-Arrival Card is a separate, mandatory step: 14 fields covering your flight, your first night, and a customs declaration, submitted online within 7 days before you arrive. You cannot file it earlier than that window, so the smart move is to set a phone reminder for the week you fly.

Sequence it like this: apply for the eVisa once your dates are firm — about two to three weeks out is the sweet spot — then handle the e-Arrival Card in the final week. If you are still deciding how long to spend, our guide on how many days you really need in Cambodia weighs a week against ten days and helps you commit before you book.

One more arrival note that catches people out in 2026: all seven Thailand-Cambodia land borders have been closed since June 2025. If your wider Southeast Asia plan involved crossing overland from Thailand, that route is off the table right now — fly into Cambodia instead. For a clean one-week trip flown in and out, none of that touches you, but it is the question we field most from travelers combining countries.

Making the most of a tight week

The whole trick to one week in Cambodia is restraint. Two cities, done properly, beat four cities glimpsed from a bus window every time. Four nights in Siem Reap give Angkor the room it deserves; two nights in Phnom Penh give the capital and its history the same. Start your temple days at dawn, take the brutal midday heat off, and you will come home rested rather than wrecked — and if you have any flexibility, choosing the best time of year to visit Cambodia makes those early starts far more bearable. The travelers who try to add the coast are the ones who wish they had not.

If you find yourself with even a couple of extra days, they are best spent slowing down what you already have — an unhurried morning at a quieter temple, a cooking class in Siem Reap, a river cruise at sunset in Phnom Penh — rather than racing somewhere new. And if you can stretch to ten days, that is when the coast or Battambang genuinely earns a place in the plan.
