I consider ‘no traffic’ to be a big part of a city’s attractions. Having experienced Manila’s traffic hell, Jakarta’s traffic’s jams, and having used to commute in traffic 2.5 hours every morning, I really really loved Siem Reap’s virtually nonexistent traffic.
But the city is so small to warrant serious traffic jams, which is why I love it even more.
Siem Reap, as many people know, is the base town for tourists who visit the ancient temple of Angkor Wat in Cambodia. The town is so small that you can actually explore it on foot. Not very comfortably and quickly, perhaps, But it is still doable.
