Built in the mid-19th century to honor the Spanish princess of Asturias, this street has a broad pedestrian walkway and is spruced up with flowers, trees, benches, and street lamps. Unfurling westward from Plaza del Inmigrante along the base of the fortified city walls, it leads to the Fuente Raíces, a striking fountain depicting the various ethnic groups of Puerto Rico. Take a seat and watch the boats zip across the water. Beyond the fountain is the beginning of Paseo del Morro, a well-paved shoreline path that hugs Old San Juan's walls and leads past the city gate at Calle San Juan and continues to the tip of the headland, beneath El Morro.
