World evils

Bloody Hell. What can I say? Just total evil. Problem is, it is still going on today in different countries.
Too rushed! Better (and cheaper) to take a tuk-tuk on your own.
, Feb 2020
NOT a "tour", NOT a "hop on hop off" as there is no other bus. THIS IS MERELY A TRANSIT BUS which waits 1:15 for you. Disappointing because the operators were more interested in rushing to make the afternoon bus schedule instead of offering the trip that was purchased. MUCH TOO SHORT to even listen to 50% of the purchased recorded guide. Advertised 1:30 per stop. Reality 1:15 per stop. Recommended AT LEAST 2:00 per stop. Better and cheaper to use tuk-tuk transportation on your own. THE FILM shown was OK, the only benefit onboard over tuk-tuk.
Pretty good, but not great
, Feb 2020
Informative, guide's English was good, but only 4/5 stars, not 5/5 because the tour was somewhat rushed and not all exhibits were visited and/or covered. If you want more time on the site, it may be better to take a tuk-tuk and hire a guide there locally.
Don’t miss the Killing Fields while in Phnom Phen

As sad as it is it’s a must do tour,It was a good way to get from S21 to Killing fields you do a self guided audio tour at both places, it was very hot on the bus but they did offer water.
Emotional & Educational
, Jan 2020
I knew the subject matter of this tour would be difficult & emotional but I think it was a necessary stop while in Cambodia.
Very moving and educational

The tour was just as described; transportation to the S-21 prison then off to the Killing Fields then back to the hotel. Water was included and a documentary about Pol Pot ran during the ride to the Killing Fields. Admission to both sites was extra and our tour guide organized the purchase of our tickets. Nothing more, nothing less.
Difficult tour, but very informative

Taking the bus and going with a company was an excellent way to see the museum and killing fields. The documentary we saw on the bus ride explained a lot about what had happened and it was nice not to have to worry about getting to the two sites, then back to the hotel. The amount of time we had at each site was just about right and the bus was pretty comfortable. I recommend this for people who want to visit this museum and site.

To see the places and S21, was so very sad, but a necessary visit whilst visiting Phomn Penh. The organisation of pick ups etc, was very good.
Good and hassle free way to see both places!
, Oct 2019
This is more of a shuttle service rather than a tour as you are collected and dropped off at your hotel and taken to the S21 Museum and then to the Killing Fields. They do however play an interesting documentary whilst in the bus. Audio guides are good at both places and would recommend this tour if you wanting a hassle free way of getting to see both places - only downside is there is only enough time at the S21 museums to do the highlights tour and would be better if they could extend duration to cover the whole audio tour.
A good trip

Bus came on time Great audio at S21 and The Killing Fields worth paying for. Good driver. Organised. Value for money.
