Begin in San Marco with St. Mark’s Basilica, ideally arriving around 10:00–10:30 to avoid the heaviest crowds. Allow about an hour for the Byzantine mosaics, marble floors, and treasury; shoulders and knees should be covered, and large bags must be left at the nearby luggage deposit. Timed admission is usually around €3–€6, while special areas cost extra. From the basilica, Doge’s Palace is immediately beside it, so there is no need for transport—just expect busy passageways around Piazza San Marco.
Spend roughly 90 minutes inside Doge’s Palace, moving through the grand institutional rooms before crossing the Bridge of Sighs. A timed ticket is strongly recommended; standard admission is generally about €30, often bundled with other civic museums. Afterward, walk a few minutes through the quieter lanes behind San Marco to Ristorante La Feluca for Venetian seafood and pasta. Budget approximately €30–€50 per person, and reserve ahead if possible—lunch service commonly runs around 12:00–14:30. Keep some flexibility here; Venice is best experienced without rushing from one campo to the next.
After lunch, walk west toward Dorsoduro, crossing Ponte dell’Accademia; allow about 20 minutes at an easy pace. At the Peggy Guggenheim Collection, set aside 90 minutes for the modern-art collection in the former palazzo, with tickets typically around €16–€18 and opening hours generally from 10:00 to 18:00; it is usually closed on Tuesdays, so confirm the September schedule. Continue on foot for about 15 minutes along the waterfront to Punta della Dogana, where contemporary exhibitions and broad views toward San Marco and the Grand Canal make a rewarding final stop. Allow about an hour, check the current exhibition hours before going, and finish outside by lingering at the triangular tip—the light over the water is particularly lovely toward sunset.
