Things to do in October

  • On a dry day, the Venetian harbour offers a short waterside walk with views of the lighthouse and old customs house. It need not take up a whole sightseeing day.
  • The Fortezza is an option for a dry day, with views of the town and Cretan Sea from the Venetian fortress. It suits an interest in historic defences and panoramas.
  • For a rainy day, the Archaeological Museum of Rethymno has an exhibition inside St Francis Church. Finds trace the region from its earliest settlements to Venetian times.
