Walk in Murano.
Trip by public ferry to Murano island
Murano is an island (connected by several bridges) in the Venetian Lagoon. The first people already settled in the 6th century and over the years it became the main spot for the venetian glass manufacturing. And it is still dominated by shops offering hand craft glass stuff to the internaitonal tourists. Allthough it is also crowded by all kind of tourists it is still more relaxed to take a walk there compared to the main island of Venetia.
The main reason for that is probably that you can reach Murano only by ferry. A couple of public ferries are available all over the island and also several stations where you can start.
