One of the best parts of traveling is walking around a city,instead of taking public transportation. Walking around cities allows you to find those lesser known locations, and little treasures. That you would have never known about if you stuck to public transportation.
1. Kuala Lumpur
The best part of walking KL is the diversity. If you start at KL central and walk to KLCC (Petronas Towers) you will walk through Chinatown, Little India, and the trendy part of town, and some quite back streets, far removed from the average tourist. This walk is great if you are only in town for a day or so, it gives you a taste KL without having to spend a lot of time fighting crowds.
Is both a great city and an awful city for walking. If your willing to accept that the streets make no sense, and on some of the narrow streets moto may run you down. It is possible to find wonderful places to walk, while taking in the culture and the history of Hanoi.
In a city plagued by awful and maddening traffic, sometimes walking is the quickest way to get around. Bangkok is like a tropical fruit on the outside it looks awful, and foreboding, but once you peel the rough outer shell back there is a delicious fruit. The same is true with Bangkok. Each side Soi (street) holds a collection of surprises for those willing leave public transportation behind.
