A guided walking tour is one of the best ways to understand Venice beyond its postcard views. Most tours last 2 to 3 hours and cover major landmarks (San Marco, Rialto Bridge, the Accademia area) while weaving through lesser-known calli and campi that you would likely miss on your own. Good guides explain the city's layered history: Byzantine trading post, maritime republic, cultural capital. Group tours typically run 25 to 45 EUR per person, while private tours for up to 6 people range from 150 to 250 EUR. Wear comfortable shoes with good grip, as the stone streets and small bridges can be slippery, especially in the morning dew or after rain.
