Five days is the first comfortable length. You can put a whole day in the lagoon, another in Cannaregio and Castello where people actually live, and still keep one in reserve for the day that goes wrong.
The plan
- Days 1–3 — As the three-day plan, without hurrying any of it.
- Day 4, morning — The Jewish Ghetto and Cannaregio. The campo, the synagogue tour if it is not a Saturday, then the long walk along the Fondamenta della Misericordia.
- Day 4, afternoon — East into Castello, out past the Arsenale gates to the Giardini. It is the quietest end of Venice and there is almost nobody in it.
- Day 5 — The things you skipped: the Campanile early, or San Giorgio Maggiore’s tower instead, which is better and has no queue. Then whatever you want to see twice.

This is the shortest trip on which a mainland day trip is a reasonable idea — but only just, and only Padua.

What this plan is built around
Not a list of sights, but the constraints: only four bridges over the Grand Canal, the market shut on Sunday and Monday, churches closed over lunch and much of Sunday morning, museums on their own weekday, a last boat back from the islands, and a tide that can put water across St Mark’s Square for a couple of hours.

Other lengths
Checked on 5 September 2026. Opening patterns, tide forecasts and boat timetables change — confirm before you travel. All sixteen sights, one page each, in Landmarks & Sights.
