The Grand Canal in Venice is always busy. It is full of vaporetti, water taxis and gondolas and lots and lots of people. It is popular because it is fabulous. On a good day Venice sparkles in the sunshine, it is magical. There is nowhere else like Venice.
A trip down the Grand Canal is one of the most wonderful things you will ever do.
I have given Venice its own category. Look there for more on this incredible place. Click here to see the island of Torcello, a completely different Venice.
