Phnom Penh ↔ Siem Reap

The most traveled route in the country, between the capital and the temple city. Three main options:

🚌 VIP Bus 8–15 USD · 5–6h
Giant Ibis, Mekong Express
✈️ Domestic Flight 40–120 USD · 45 min
Cambodia Angkor Air
🚤 Speed Boat 35–50 USD · 5–6h
Tonlé Sap, scenic
🚐 Shared Van 12–18 USD · 4–5h
Faster but cramped

Our recommendation: VIP Bus Giant Ibis (morning departure, arrival around 1-2 PM). Comfortable, WiFi, luggage included, punctual. Book the day before during high season. The speed boat is tempting but the crossing of Tonlé Sap can be bumpy — save it for the dry season and choose a reputable operator.

🚌 VIP Bus 8–12 USD · 4h30
Multiple departures/day
✈️ Flight 40–80 USD · 45 min

Avoid low-quality night buses on this route. Several serious accidents have occurred in recent years on National Road 4. Reputable companies (Giant Ibis, Mekong Express) do not operate at night. If someone offers you a night bus for 4 USD, run away.

Direct route
🚤 Speed Boat 25–35 USD · 7–8h
Very popular, scenic

The Siem Reap–Battambang speed boat via Tonlé Sap is one of the most spectacular journeys in Cambodia — floating villages, rice fields, birds. But it lasts 7 to 8 hours and only operates during the rainy season (June-December) when the lake level is sufficient.
