There are two types of travelers, active and passive—1.) Those who like to hoof it, taking in the best of sites on foot and 2.) Those who prefer the big red double-decker bus thingamajigs. The latter return to the hotel, tired and ready for another meal while the former, none for the better, return exhausted though feeling content with a little exercise. If you are of the latter range, you may wish to read not; if, however, you are of the former style, then let me treat you to some of the best cities 'round the spherule for stretching your legs.

(Excuse me? Can the author have a word? Ok listen: I'm biased. I'm only going to tell you about the cities I've actually sauntered through, in no hierarchal order. This is not some regurgitation of another inescapable web filler article. Enjoy.)

Vienna, Austria: The streets are wide. The streets are shady. The streets are lined with majestic palaces, gothic cathedrals, opera houses, old and new architecture latticed into one. Bike friendly, pedestrian friendly and plenty to see are what make Vienna a wayfarer's way. In my opinion, walking is the only way to truly tour this storied old city.

Paris, France: Before you say that I'm hugely predictable in my Europe-centric picks, just read these first before passing shrewd comments. France is simply set up for walking, hands down: from the countryside to the cityscape, there are paved, marked paths for human powered transportation; from downtown to the Bois de Boulogne, there's a path for we of hoof power.

Portland, Oregon: Probably more bike path focused, this epicenter for those using legs to transport thorax and head should be a beacon to the rest of the urban planners. Portland, like San Francisco, started pedestrian-conscience while other cities—like Detroit—gave into industrial powers. Why would people with cars need walking/biking paths?

Czech Republic: Again, bike paths and walking paths unite as one, separated only by a yellow or white line. In Czech, the powers that be have webbed pedestrian paths throughout the country (they even link up into other neighboring countries). Prague, Brno, and even Liberec leave space for urban hikers.

Vietnam: Everyone in Vietnam still rides a bike. Perhaps a stereotype, I rode a bike through the whole country, only to meet thousands of waves of locals walking and peddling to and fro. Normally, too, I could get around on foot in any of the tourist locales. It is amazing how happy and healthy people look when walking or riding a bike is the only and main form of transportation for most people.

Rabat, Morocco: Though the fuming exhaust of grand and petite taxis set the pace, it is quite possible to stroll to all the favorite sites. Try walking along the senescent old walls of the oudeh (Udaya), up to the surf club. A trip through the medina and by several mosques make sucking muffler smolder all worth it.

Vancouver, Canada: We in the US must love our northern neighbors. They make the list with Vancouver, a city really built around the multi-cultural student population (students love to get out and about). With several recreational islands to take away school and work related stress, Vancouver proper has done a fine job with maintaining a port city with an almost hanging-verdant tropical ambiance. Montreal does a good job too for foot traffic, though a very short warm-weather window allows a short outdoor strolling season.
