The bus journey to Phomn Penh was a very quiet one. It's fair to say we all felt pretty rubbish and were doing our best to concentrate on not vomiting. The journey itself was the easiest border crossing we've done, all we had to do was crawl over the border and had no trouble whatsoever. Quite unexpected after the stories we had heard about Cambodian border control!

We arrived into Phomn Penh late that afternoon, and unlike normal just collapsed in our rooms. After a little snooze we felt more human so headed out for some food in the city. The city is a confusing place to explain, it's not built up but it's also not totally run down. You can see the poverty immediately and there are far less westerners than Vietnam. It feels like you're seeing real life again.

The next day we decided to tour the city and see the sights. We started at the market which we always love. Lots of good quality fake goods. Apparently lots of things are made in Cambodia so most things at the market are actually real. Either way they're cheap so we don't mind!

After that we headed to see the main sight, the Royal Palace. This place is incredible, one of the most beautiful things we have seen in a long time. Inside is the famous Silver Pagoda, equally as beautiful and well worth a visit.

On our way back to the hostel we decided to stop at the bridge where the disaster was recently. It's so small it's really hard to believe that many people died there. There were still a lot of Cambodian people paying their respects and the area is still closed off.

Our final day was the day we had all been dreading. We were going to spend it visiting the Killing Fields, then the S21 museum. To start the day the lads decided to visit the shooting range. They were able to shoot an AK47, Tommy gun, M4 and an M18. You never really realise how loud these guns are until you hear them, they are very scary. The lads thoroughly enjoyed it and Laura even shot a bullet from an M4.

After that we left to visit the Killing Fields. For those of you who don't know what it is, this is where the Khmer Rouge (lead by Pol Pot) killed millions of Cambodians during the 1970s in an effort to 'cleanse' the population. There are still mass graves that haven't been unearthed yet. Because of the regime currently over 50% of the Cambodian population is under 16. The Killing Fields themselves was the extermination camp that people were sent to after torture in S21 to be 'liquidated'.

The first thing you see when you arrive is a monument consisting of hundreds of skulls. From there you go into a museum to learn more about what happened. After you are given a chance to walk around the grounds. At one point you visit a tree which was used to kill babies. The Khmer Rouge decided all babies must be killed to stop them taking revenge when they grew up and they used the tree as a way to save on bullets. Pretty horrendous.

After the Killing Fields we headed to S21, having been warned that it's not for the squeamish. This was originally a school, which later turned into a torture camp. Each of the classrooms were divided up into cells and you can still wander through them. However worse to come is that photos were taken of every prisoner when they arrived, but also of each of them once tortured. These pictures are all on display and were really upsetting to see. There are also accounts from people who lost family during the regime which are heartbreaking.

As you can imagine this day was pretty terrible, but not something you can turn a blind eye to while visiting Cambodia. Lots of the beggars are missing limbs and severely disfigured from what happened in the 1970s. We all left feeling pretty numb and not really knowing what to say. They believe that the Khmer Rouge regime is an example of the worst thing that mankind could ever do to one another.
