Price for official licensed guide depends on language, English speaking guides usually ask $40-$60 at high season and $40-$50 at low season, other languages are more expensive.

Drivers can't be guide since it is forbidden for them to leave car within Angkor archaeological park. Car with driver cost $30-#120 - depends on path, usually Small Circle cost #30-#40, Big Circle $45-$60, I'm about sedans like Toyota Camry. Remote temples like Preah Vicher will cost about $120.
