For western visitors, Phnom Penh can be a bit of rough change, especially from surrounding Vietnam or Thailand. The city is characterized by warmth and humidity, infrastructure that is lacking, risky traffic, harassment from tuk tuk and moto drivers, and a certain level of sex tourism. All that said, the city is slowly gaining high-rise buildings and traffic lights, while still retaining some of the beauty that made it a Paris of the East before 1970. The city's few French colonial buildings and traditional Cambodian architecture make a handful of its streetscapes a beautiful and pleasant walk. There are some beautiful wide boulevards, and a park like riverfront with cafés and restaurants aplenty. The standard tourist sights are few, but include the National Museum and Palace, as well as the Killing Fields and Torture Museum, remnants of the Khmer Rouge regime that devastated the country in the 1970s. However, as a place to relax, watch the street life and absorb local color, Phnom Penh is a worthwhile destination for those who enjoy an 'edge' experience and can brave the downsides.
