Is Phnom Penh worth visiting?
Yes. While the tourist attractions can be seen in a day, two at the most, the city has a bit of character and it’s worth spending an extra day or two just hanging out and absorbing the energy of the place, which being Cambodia, is a rather odd sort of energy. I will point out, though, that while they have cleaned the place up a bit and kicked out a lot of the homeless, there are still some harshly real visible signs of destitute poverty here. If you’re one who prefers to deny the existence of such things, then you might give Phnom Penh a miss. Actually, if poverty really makes you uncomfortable, avoid Cambodia and stick to the west. Upon arrival in Phnom Penh I suggest getting Canby Publications free guide book, The Phnom Penh Visitor’s Guide or see their website (linked to above).
