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.
