Quick answer
What is São João like in Porto?
São João is Porto’s biggest street celebration, especially on the night of 23 June. The most famous moments happen around the historic centre, Ribeira, Gaia and the Douro River, with fireworks at midnight and crowds walking through the city until late.
Expect a lively, crowded and joyful night. It is beautiful, intense and very local, so the best way to enjoy it is to arrive early, wear comfortable shoes and move slowly between the main areas.
