How to reach Museum Correr in Venice
The entrance to the museum is on the far right side of Piazza San Marco. Turn your back towards the Basilica San Marco and you will see a large red sign saying Museo Correr on the other side of the square. If you desire to reach Piazza San Marco by water buses, you can use the following lines:
Vaporetto (Venetian water buses) lines: 1,2 (stops: San Marco Vallaresso or S. Marco-S. Zaccaria) B, O (stop S. Marco - S. Zaccaria).
On the other hand, if you decide to walk from Piazzale Roma, it will take you around 40 minutes depending on your rhythm of walking.
