A tranquil 55 acres inhabited by 7500 hundred plants, the garden delights plant nerds, walkers and picnickers - especially on warm days!
Within Golden Gate Park and close to the Cal Academy of Science and de Young Museums (and just a bit further to the Conservatory of Flowers), the Botanical Garden combines nicely with other adventures.
Guided walks start daily at 1:30
