Time Out says
This park has staying power: During the 1906 earthquake, the homes atop Bernal Heights rock were some of the only to escape damage. It's a worthwhile 30 minute walk up a dirt path to the park's peak, which offers 360 degree views of the bay, downtown, the Golden Gate Bridge, the East Bay and San Bruno mountain. In spring, the slope blooms with wildflowers and native grasses, and the site is home to more than 40 species of birds. Neighbors convene at the dog park in mornings and at dusk. Don't miss the rope swing at the top of Bernal Heights hill, which creates the impression of swinging across the entire city.
