This iconic bridge, a top 10 attraction in Porto, connects the city with Vila Nova de Gaia. I was fascinated by its unique design, featuring two decks for pedestrians, vehicles, and even a metro line. Walking across the upper level, I marveled at the sweeping views of the river and cityscape, pausing to capture photographs and breathe in the fresh riverside air. Descending to the lower level, I discovered a vibrant atmosphere filled with street performers, artists, and local vendors. Whether viewed from the water, the riverbanks, or the bridge itself, Dom Luís I is a quintessential Porto experience.
