Cross the Charles Bridge at dawn.
Best crossed when it’s bereft of tourists—at daybreak. Commissioned by King Charles IV in 1357, this stone bridge is a replacement for the one that was washed away by a flood. Designed by Peter Parler, the same architect of St. Vitus Cathedral, it is 500 m. long, features 30 religious statues, and offers some of the best views of the city. If you get there a bit later than sunrise, be mindful of your belongings —pickpockets populate the bridge, eager to rid you of your valuables.
