Petřín Hill & Lookout Tower

Take the funicular up (it has its own fare, 100 CZK, or 90 CZK in the PID Lítačka app; 30- and 90-minute transport tickets aren't valid, but 24- and 72-hour tickets are) and you're rewarded with orchards, a rose garden, a mirror maze, and the 58.7-metre Petřín Tower — built in 1891, deliberately modeled on its Parisian cousin.

This is where locals go to escape the Old Town crowds entirely. Bring a picnic in spring, when the fruit trees blossom.
