6 Best Sights in San Francisco, California

One of the city's best free offerings, this museum is an absolute must for kids and compelling for adults too. You can even ride a cable car here—all three lines stop between Russian Hill and Nob Hill. The facility, which is inside the city's last remaining cable-car barn, takes the top off the system to show you how it all works. Eternally humming and squealing, the massive powerhouse cable wheels steal the show. You can also climb aboard a vintage car and take the grip, let the kids ring a cable-car bell, and check out vintage gear dating from 1873.

Snoopy, Wonder Woman, Batman, and other colorful cartoon icons greet you at the Cartoon Art Museum, established with an endowment from the late cartoonist-icon Charles M. Schulz. The museum's strength is its changing exhibits, which have highlighted subjects such as emerging artists, the evolution of animation, and artwork that highlights the landmarks of San Francisco. Serious fans of cartoons—especially those on the quirky underground side—will likely enjoy the exhibits; those with a casual interest may be bored. The store here carries cool titles to add to your collection.

Architect Daniel Libeskind designed the postmodern CJM, whose impossible-to-ignore diagonal blue cube juts out of a painstakingly restored power substation. A physical manifestation of the Hebrew toast l'chaim (to life), the cube may have obscure philosophical origins, but Libeskind created a unique, light-filled space that merits a stroll through the lobby even if the current exhibits (the museum is non-collecting and does not have permanent holdings) don't entice you into the galleries. Exhibits, usually two or three at a time, vary, from a look at the history of famous puppeteer Frank Oz (Star Wars and the Muppets) to an immersive series about the 19th-century Jewish immigrant and photographer Shimmel Zohar. San Francisco's best Jewish deli, Wise Sons, operates a counter in the museum. Try their smoked salmon bagel sandwich or a slice of chocolate babka.

Once a staple at Playland at the Beach, San Francisco's early-20th-century amusement park, the antique mechanical contrivances at this time-warp arcade—including peep shows and nickelodeons—make it one of the most worthwhile attractions at the Wharf. Some favorites are the giant and rather creepy "Laffing Sal"; an arm-wrestling machine; the world's only steam-powered motorcycle; and mechanical fortune-telling figures that speak from their curtained boxes. Note the depictions of race that betray the prejudices of the time: stoned Chinese figures in the "Opium-Den" and clown-faced African Americans eating watermelon in the "Mechanical Farm."  Admission is free, but you'll need quarters to bring the machines to life.

Dedicated to the influence that people of African descent have had in places all over the world, MoAD focuses on temporary exhibits in its four galleries over three floors. With floor-to-ceiling windows onto Mission Street, the museum fits perfectly into the cultural scene of Yerba Buena and is well worth a 30-minute foray. Most striking is its front window centerpiece: a three-story mosaic, made from thousands of photographs, that forms the image of a young girl's face. Walk up the stairs inside the museum to view the mosaic photographs up close—Malcolm X and Muhammad Ali are there, along with everyday folks—but the best view is from across Mission Street.

A labor of love from the same vintage-transit enthusiasts responsible for the F-line's revival, this one-room museum and store celebrates the city's streetcars and cable cars with photographs, models, and artifacts. The permanent exhibit includes the replicated end of a streetcar with a working cab—complete with controls and a bell—for kids to explore; the cool, antique Wiley birdcage traffic signal; and models and display cases to view. Right on the F-line track, just across from the Ferry Building, this is a great quick stop.
