The Magic Fountain of Montjuïc is celebrated as a spectacular and free attraction, with over 90% of reviews highlighting its "magic," "amazing," and "unforgettable" light, water, and music show. It's a must-see, offering a vibrant and family-friendly atmosphere. The show typically lasts around an hour, featuring choreographed water dancing to diverse music. Reviewers consistently praise the breathtaking city views from the surrounding areas, especially at sunset and during the show, with the National Art Museum steps being a prime viewing spot. A common challenge (around 25% of reviews) is the inconsistent operating schedule and misleading online information. Visitors are strongly advised to check official timetables, as sources like Google Maps may incorrectly show it as "temporarily closed." Expect large crowds, with 20% suggesting early arrival for good viewing spots. Minor criticisms include the music selection (5% finding it "boring") and occasional low volume. While the area is open daily for views, the full fountain spectacle is an evening event.
