1. Ribeira: Take in the Douro waterfront
Ribeira's riverside streets give you a lively place to stroll beside the Douro and watch the city lights come on. A large or city-organized fireworks display has not been confirmed for 2026-2027, so treat this as a scenic spot rather than a guaranteed viewing point. The waterfront is a good base for soaking up the New Year atmosphere, but expect crowds if many people gather by the river.
