Giant Ibis's night bus has no hotel pickup, so you make your own way there. ### Arriving in Siem Reap Giant Ibis ends at its terminal **behind the Old Stadium**, near Khmer Pub Street, where tuk-tuks wait. Other companies stop at their own offices in town, so check the drop-off on your ticket. Flights land at **Siem Reap Angkor International Airport (SAI)**, well outside town; the [Siem Reap airport guide](/siem-reap-airport/) covers the shuttle bus and taxis. ### Luggage, check-in and tickets Giant Ibis's route page asks you to be there **30 minutes** before departure and lists **20 kg** of luggage; its general terms say 35 minutes and 25 kg. Go by what your ticket says. Its direct tickets are non-refundable but can be changed once with 24 hours' notice; a ticket bought through another seller follows that seller's conditions. ## Siem Reap to Phnom Penh By bus: the same companies run back from Siem Reap to Phnom Penh through the day and overnight, about six hours, with Giant Ibis at about USD 19 sold online for October 2026. Giant Ibis leaves from behind the Old Stadium and ends on Street 106 in central Phnom Penh. ### Siem Reap to Phnom Penh time and price | Fact | Detail | | --- | --- | | Usual way | Bus or night sleeper bus | | Typical time | About 6 h | | What it costs | Giant Ibis about USD 19 | | Where it departs | Company terminals in central Siem Reap | ### Buses from Siem Reap to Phnom Penh | Operator | From | To | Typical time | Fare | Notes | | --- | --- | --- | --- | --- | --- | | Giant Ibis | Giant Ibis terminal, behind the Old Stadium | Giant Ibis terminal, Street 106 | About 6 h | About USD 19 online | | | Larryta and other bus and van companies | Company offices, Siem Reap | Company offices, Phnom Penh | About 6 h | Varies by company | | ### Leaving Siem Reap Giant Ibis leaves from its terminal **behind the Old Stadium**, near Khmer Pub Street. On the day service its schedule mentions pickup from partner hotels; other companies board at their own offices. ### Arriving in Phnom Penh Giant Ibis arrives at its **Street 106** terminal by the Night Market in central Phnom Penh. If you are flying out, [Techo International Airport](/phnom-penh-airport/) is about 20 km south of the centre, so leave time to get there. ### Before you board The day buses stop on the way; Giant Ibis's day schedule mentions a 30-minute break at Prey Pros. Wi-Fi on board can drop out in the countryside. ## Quick Facts - Departure: Phnom Penh - Arrival: Siem Reap - Main transport: bus - Last checked: 2026-10-16 - Confidence: high ## Six hours by road, day or night Siem Reap is about **320 km** north-west of Phnom Penh, and the bus takes about **six hours**. It is the usual way to go: for late October 2026, more than 250 departures by bus, van, taxi and air were on sale online for a single day. **Day or night.** Day buses leave from early morning to early afternoon and arrive before dark. Night sleepers leave late in the evening and arrive around dawn. Giant Ibis's night bus has the fleet's only onboard toilet and makes no bathroom stops, only a short driver change in Kampong Thom. Its beds are 1.8 m long, with one 2 m bed at the back. **Vans** are a little cheaper and sometimes quicker, but you have less room for bags and legs. The [bus guide](/bus/) compares seats, sleepers and vans across Cambodia. **Flying** takes under an hour, but you still have the drive out to Techo airport and in from Siem Reap's airport, so door to door it saves less time than it seems. **The boat.** Cambodia River Express has sailed across the Tonle Sap at weekends while the water is high, 6 to 7 hours, and went boat-only in January 2026. No sailing was on sale for October 2026 and its website was offline, so confirm with the operator before planning on it; the [ferry guide](/ferry/) lists the river boats. ## Phnom Penh to Siem Reap bus times **Giant Ibis timetable (operator):** - **Phnom Penh to Siem Reap:** 08:45, 09:45, 12:30; night 22:30, 23:00 - **Siem Reap to Phnom Penh:** 08:45, 09:45, 12:30; night 22:00, 22:30 **Also on sale for October 2026:** - **Larryta sleeper buses:** 07:35, 10:10 and 13:10, about 6 hours - **Vans** (Larryta, Cambolink21 and others): roughly hourly in the morning - **Overnight buses** (Virak Buntham, Olongpich and others): from around midnight, arriving early morning ## Bus and flight prices to Siem Reap **Sold online for late October 2026, one adult:** - **Buses:** from about USD 9 - **Vans:** from about USD 10 - **Larryta sleeper:** about USD 18 - **Giant Ibis day bus:** about USD 17 to 19 - **Giant Ibis night bus:** about USD 21 - **Private taxi** (up to 4 people): from about USD 70 per car - **Flights:** from about USD 88 Prices change with the date and the seat, so check yours when you book. ## Arriving in Siem Reap and going on Most visitors come for **Angkor**.
