Time Out says
Established as a military base in the mid-19th century, today the Presidio is more than two square miles of swaying eucalyptus and gorgeous views. While the Presidio has major landmarks such as like the Walt Disney Family Museum, which occupies a 19th-century army barrack at the Main Post, it also has endless nooks and crannies just made for stumbling upon. Like art? Check out the Presidio’s two outdoor Andy Goldsworthy creations—the Wood Line, which parallels Lover’s Lane, and the Spire, which towers over the Bay Area Ridge Trail. History buff? Visit what’s left of the 200 year old adobe home of Juana Briones at El Polin Springs or admire the tombstones memorializing beloved dogs and cats at the Pet Cemetery near Crissy Field. And if you seek something a little more, well, Star Wars-ey, Yoda holds court every day from atop the fountain in front of the Lucas Film building.
