Burano is one of the islands in the Venetian Lagoon. Enjoy the scenic, and often refreshing 45 minute boat ride to the color palette village. In the crushing heat of the summer, I know nothing better (other than gelato) that cools like a vaparetto ride.
Burano is a fishing village with brightly colored buildings to help the fisherman see the island in the fog. Besides the mosaic of color, you can also meet the lace makers. There are the touristy shops, but mixed in you can find the families that have been making lace for generations.
If the crowds of Venice are bringing you down, a side trip to one of the islands might be a necessary escape. These smaller islands still have tourists, but not gobs of them clogging every canal. If you really want to see Burano at its best, I recommend the early evening. As the light becomes less harsh, the colors come to life under the shadows. You can also expect to see less people the later you stay. Just make sure you don’t miss the last vapareto back!
