The Walt Disney Family Museum
104 Montgomery St., Presidio
Founded by Walt Disney's daughter, Diane Disney Miller, this 40,000 square foot space in the Presidio offers an incredible view into the mind that created the whole concept of animation, whether you have little fans of Mickey on your hands or not. There are elements from his whole life on display, including many drawings from when he first landed in Los Angeles with $40 in his pocket. There's also a fascinating 13-foot model of Disneyland on site, rendered according to Walt Disney's original vision.
Julius Kahn Playground
West Pacific Ave. & Spruce St., Presidio
Inspired by the playgrounds in the Luxembourg Gardens in Paris, this beloved spot is particularly good for older kids, as much of the climbing equipment is more challenging than your typical slide structure. That said, there's a designated spot for smaller kids that's not as intimidating. There are also hiking trails throughout the Presidio (with views of the Golden Gate Bridge), along with tennis and basketball courts and playing fields.
