WHAT SHOULD I WEAR?

Best to dress for Autumn including at least one medium weight jacket or coat and a couple of  sweaters.

A scarf & hat and perhaps a pair of gloves might come in handy on those colder and windy days. If a chilly morning tour warrants gloves, be sure to get ones that have touchscreen capabilites so you can still take photos on your phone. We use these from Agloves because they have gripper dots on the palm to help hold things!

Wear sensible shoes as the cobblestone streets can be slippery when wet.

An umbrella will also come in handy during those wet days. We recommend a pocket umbrella, like this one.
