from Ponte Rialto u'll be able to catch one of the most beautiful panoramas in venice, just follow the signs, its very famous there, make sure you're there in the sunset time its amazing!
When you walk around Venice, you inevitably get lost, so you keep coming across the same bridge or Campo, again and again, only you may not realise it!
After such a wide promenade, when you get to a bridge its cattle time as you all are hearded over, maybe this should be a tourist trap.
Ponte Rialto or Rialto Bridge
The Rialto bridge is the most known bridge across the Canal Grande.
