I only discovered how ‘fun’ flea markets were once we had moved to Portugal. Desperate for more English books some good friends suggested we tried the local flea market. We arrived early and the whole place was a hive of activity with people looking for a bargain and bartering in various different languages. A real multicultural experience! I soon discovered you could virtually buy anything from fresh fruit and veg, local honey, handmade jewelry, plants, English food, books and a whole assortment of bric-à-brac which people no longer required and were selling to make a few euros.
If you are visiting Portugal this is a good opportunity to really rub shoulders with the locals.
You may even pick up a bargain!
