Unfortunately I did not spend a lot of time in Phnom Penh, as I only used it as a transit stop to get up to Siem Reap and back. I did get a couple of chances to go into the city, and it is a crazy and vibrant Asian city that is definitely worth exploring.
The Central Market
When I got to the Central Market most of it had closed, but a lot of the food places were still open and some of the other stalls. This is a great place to get souvenirs and try local foods.
