Why we say this
Insider secrets & local vibes
Acqua alta itself is part of Venice: rubber boots, raised passerelle across a flooded Piazza, warning sirens, the city's fight against the sea now backstopped by the MOSE barriers.
Not independently verified — estimated
It's weather-dependent and unpredictable, and severe floods genuinely disrupt with closed sights and soaked feet.
Not independently verified — estimated
There's no public tour of MOSE itself; it's context, not a ticketed sight.

Best time
Mainly autumn/winter high tides; watch the tide forecast and listen for the siren codes.

Accessibility
Flooding and narrow raised walkways are very difficult for wheelchairs and strollers.
