Burano Island is a very plesant trip on the large public boats you can catch at Zaccharia (San Marco). Burano is different than the other islands in that all the houses and business are very colorfully painted. Legend has it that the owners painted their house colorfully so they could see them easily when returning from the sea.
The island has one main street and several offshoots. The businesses mostly sell beautiful lace and other fabric clothing, table cloths, etc. The inhabitants at one time made all these items, but now most come from the far east. Italians are too well paid ... and the fantastic lace creations, already very expensive, would be astronomical if actually still made on Burano. Bring your camera, if you are a serious photographer you will be in heaven.
