Ponte de Dom Luis I, Porto

Whether you're crossing sides, admiring the architectural design of the bridge, or taking an evening stroll, this is a spot you have to see on your stay in Porto. The metro line crosses over it which makes it really easy to reach, but be careful as you're walking along not to stray onto the road! You can get some fantastic views of both sides of the city, but mind where you stand as lots of people will be walking along the pavement too.

Possibility my favourite bridge in the world! This beautiful landmark is a must visit in Porto. The bridge had a upper level, lower level and a tram that crosses it. The best way to experience it is walking across the upper level. It is safe for children. I love that you can see both sides of the Douro river.
