There's No Angkor Bus Tour, Really
Search “Angkor bus tour” and you’ll find plenty of listings selling a vehicle that doesn’t exist here.
The correction that actually matters
Siem Reap has no municipal public buses and no scheduled hop-on hop-off tourist bus running between Angkor Wat, Bayon, and Ta Prohm. What gets marketed as a bus tour of the temples is, in practice, a private air-conditioned minivan or an open-air tuk-tuk, locally a remorque, with a driver for the day. If a listing also names Chong Kneas as a floating-village stop, treat that as a second red flag: that particular village is known for predatory ticket touts and forced stops at fake “orphanage schools” pressuring visitors into buying overpriced rice. Kampong Phluk or Prek Toal are the honest alternatives.
What a real temple day actually costs
A remorque for the day runs about $15 to $20 for the Small Circuit (Angkor Wat, Bayon, Ta Prohm), $20 to $25 for the Grand Circuit (Preah Khan, Neak Pean, Pre Rup), and $25 to $35 for more distant temples like Banteay Srei, plus $5 if you want the sunrise start. Air-conditioned minivans cost more and suit bigger groups or the hottest months better than an open-air tuk-tuk does. In town, Grab and PassApp cover short hops between hotels and restaurants for $1 to $3, no haggling required.
Where actual buses do exist
Real coach buses run intercity, not around the temples. Giant Ibis is the standard-setter: Wi-Fi, power outlets, seatbelts, and assisted border crossing on the roughly 8-hour run to Bangkok, plus routes to Phnom Penh (5 to 6 hours) and Battambang (about 3 hours). Mekong Express and Virak Buntham cover the same routes at lower prices, including night-sleeper options.
Cash rules that catch people out
Bring pristine US dollar bills for any cash fare or ticket purchase. Cambodian counters reject notes with tears, ink marks, or heavy creases, no matter how minor, and a driver won’t make an exception for you at the roadside. High-denomination $50 and $100 notes get checked especially hard for counterfeits, so break large bills at a bank or hotel before you need small cash for a tuk-tuk fare.
Verdict: stop searching for a bus tour of the temples and book a tuk-tuk or minivan day instead; save the bus line for the trip out of Siem Reap once the temples are done, and book that seat a day or two ahead in high season.
