Photo: GetYourGuideThis well-reviewed three-hour walk is the easiest way to get your bearings, led by a local guide who threads together the cathedral, Sao Bento station, Clerigos and the Ribeira with the stories behind them. Groups are small and the pace is gentle. Wear comfortable shoes for the hills and cobbles. It is a smart thing to do on your first morning, as the guide will happily point you to their favourite spots for lunch.
