At 7 350 ft / 2 240 m above sea level (Mexico City, Mexico)
The famous Lagunilla of Mexico City is the most traditional flea market in the city. This flea market takes place every Sundays and is attended by a variety of individuals, from antique dealers, to city dwellers and tourists in search for antiques (“antigüedades” in spanish).
However, what makes this flea market truly unusual, besides its selection of antiques & crafts with their very own Mexican and colonial flavor, is its topographic point: Mexico City, has an average elevation of about 2 250 meters (7 400 ft.), which makes it the 5th highest capital city in the worldafter Lhasa (Tibet), La Paz (Bolivia), Quito (Ecuador) and Addis Ababa (Ethiopia), and the 1st highest by its population.
Travelers will first discover that it is a little more difficult to walk as fast as they normally would, but they just need to slow down a bit and they will be fine. Anyway, who is in a hurry while visiting a flea markets?
