Rather than castles and squares, guides offer personal anecdotes of what it's like to live on the streets.
Last year, five million tourists poured into Prague's bohemian bars, picturesque castles, and centuries-old alleyways.
A handful also had the opportunity to see a different side of the city. Pragulic, a student-run tourism company, offers tours hosted by homeless men and women. Rather than hit up the city's hot spots, these guides offer more personal tours of the landmarks of street living. This could include a trip to a used book store where a guides sells books collected from garbage cans; a visit to a square where he mines the dumpsters for food; and a trip to a fountain to collect drinking water.
Tours cost $10; guides keep half of that money.
Homelessness has become an increasingly pernicious problem in Prague. According to the radio show The World, there are about 4,000 men and women on the streets, up 7 percent from last year.
