We literally walked into Cambodia (old name Kampuchea) from Vietnam. It's a striking contrast in terms of rural architecture and way/standard of life. Cambodia had a mixed fortune through the centuries. A glorious, regional superpower in ancient times, Kampuchea suffered horrible communist regime which killed estimated 3 million of its own people in just 3 years. That'd happened only 30 years ago, it was in our lifetime - Where was the world then? Now Cambodia is opening to the world economy and tourism and is embracing a new, better future.
Featured: We traveled by cyclo for sightseeing tour of Phnom Penh to include the Royal Palace and the Tuol Sleng School turned into prison, now museum. We visited the Cheung Ek Killing Field and the Russian Markets, Spider Village, rural Kampuchea, shallow but very large during wet season Tonle Sap Lake and floating fisherman villages.
