We explored this part of Lisbon as part of a Free Walking Tour. There is no initial cost for the tour, which lasted about 3 hours. At the end of the tour you give the guide a tip, depending on how you found the tour. We later went back to this area and had a more in depth look around. The old parts of Lisbon are the most interesting and unique. It was on this walking tour that we tried home made 'Ginja' - a liquor made from cherries, sugar & cinnamon. It was delicious!
Tip: To find a free walking tour, just Google 'free walking tours in Lisbon' & there they are! Some have to be pre-booked, others you just show up at a specific time & place. Your choice!
There are also many great places to enjoy the local cuisine in this area. You can explore and snack as you go! :)
