In general, Prague is safer than most large cities in Europe. Precautions against pickpockets are necessary—you will even notice ads in metros reminding you to watch your belongings—so divide money among several places in your personal belongings. You certainly don't need to wear your backpack on your chest, but be mindful of open bags or accessible wallets, and if you're wearing a backpack, be sure to keep it locked.
Be particularly alert of the following areas: Charles Bridge; the Astronomical Clock in Old Town Square; between Wenceslas Square and Prague Castle; Trams 9 and 22; and the Mustek, Muzeum and Florenc metro stations. It's not uncommon for organized pickpocket gangs to work the metro or the trams, especially during peak hours. Be wary of groups of people who suddenly decide to get on the tram at the last minute from different doors. If there is any pushing to get on the transport, keep a hand on your wallet.
Also be wary of phony ticket inspectors trying to assess fines on Prague's crowded public-transportation system. All legitimate inspectors carry small oval badges with red logos that they must present before checking your ticket.
Exercise the same precautions you would when walking in any large city and be aware that many side streets are poorly lit. Though Petrin Hill is a lovely place to walk during the day, be careful alone there at night. In general, it's best to avoid any secluded area after dark. Prostitution is on the rise, and men will likely be approached when walking around in the evening—watch your wallet.

Dos & Don'ts
Do try to be quiet on public transportation. You will find that most of the locals use their museum voices on the metros and trams.
Don't be offended when you are bumped. Czechs tend to bump shoulders without apologizing—it does seem rude from a western perspective, but it's the daily routine there.
Do say dobry den (hello) when entering a shop and na shledanou (goodbye) when leaving. It's not only polite, it's part of the culture.
Don't be offended when stared at. Again, that's just the way it is there.
Do be careful with large bills. Even though bank machines will distribute 1,000 Kc and 2,000 Kc notes, it doesn't mean that every shop will accept them. Restaurants and hotels generally have enough change to accept them, but taxi drivers and smaller shops generally do not.
