The Font Lluminosa, not to be confused with the Luminous Fountains, are in the Paseo Jaime I, pretty much next to the port. They offer a nice water, light and sound show during the summer months. The jets draw whimsical fonts and bright pictures while classical music and other melodies play. It's very nice, but I always have doubts whether the cost of maintaining those fountains could have been used more wisely throughout the town. It always gives me the feeling that the town is thinking more about tourism for 15 days in the summer than year round residents. Anyway I recommend making a point to see them, which is great fun for children and adults.
