"A 1,200-acre green space filled with museums, theaters, and gardens, Balboa Park is the center of art and culture in San Diego . It’s also one of the city’s most historic sites, built for the Panama–California exhibition in 1915. While the museums are definitely worth seeing, there are also a number of free attractions, including the photogenic Botanical Building, which houses more than 2,100 plants (including Venus flytraps); the Desert Garden, filled with succulents from around the world; and a sculpture court with works by Miró and Rodin. For one of the area’s best views, purchase a timed ticket to climb the California Tower in the Museum of Man. The ornate structure reopened to the public in 2015 after being closed for nearly 80 years and features a spiral staircase to the eighth floor, where you can catch a glimpse of the Cuyamaca Mountains, the Cabrillo Bridge, and even Mexico ’s Coronado Islands."
