1915 Beaux-Arts rotunda and colonnades built for the Panama-Pacific Exposition. Grounds and lagoon free to visit year-round. Indoor theatre (1,000 seats) hosts concerts, ballet, comedy, cultural performances.
Acoustic sculpture at the tip of a jetty. 25 PVC organ pipes make music from bay waves. Views of Alcatraz, Golden Gate Bridge, and the skyline. Go at high tide for the best sounds; at low tide the pipes are basically silent. Full moon tides are loudest. 1.8-mile trail connects to Crissy Field.
300+ coin-operated mechanical machines from the 1800s to 1990s. Free admission, machines cost a quarter or fifty cents each. Bring $5-10 in coins. The oldest machines in the back (fortune tellers, execution dioramas) are the best part. Open 365 days.
Free museum inside the actual cable car barn and powerhouse. Watch the massive winding wheels pulling 9.6 miles of cable at 9.5 mph from the mezzanine. This is the real system, not a replica. Three antique cable cars from the 1800s. Donations cash only. Wheelchair ramp on Washington St side.
163 tiled steps with a sea-to-sky mosaic, completed in 2005. Best photos before 10am or after 4pm. Take the N-Judah to 15th & Judah and walk up, or get dropped at the top. Tiles can be slippery. Grandview Park nearby for city views. Residential area, keep it quiet.
Two steep concrete slides built into a hillside, designed by a 14-year-old in the 1960s and opened in 1973. Choose the red slide or the yellow slide (steeper and faster). Bring cardboard to sit on — without it, the concrete friction slows you down and ruins your clothes. Locals grab flattened boxes from nearby stores. The slides are steeper than they look and the yellow one is legitimately thrilling. Hidden in a residential area and easy to walk right past.
Free museum about the science of sight, run by the American Academy of Ophthalmology. 38,000+ artifacts including antique surgical instruments, optical illusions, and exhibits on how vision works. More interesting than it sounds. Most people walk right past it on the way to Ghirardelli Square.
Outdoor food truck park with trucks rotating from 200+ Bay Area operators. Free entry, food $10-18 per item. Fire pits, lawn games, bar. Weekday lunch has short lines; Fri/Sat evenings are packed. Dogs welcome. Check @sparksocialsf on Instagram for daily lineups.
Free outdoor concerts in a natural eucalyptus grove amphitheater, running Sunday afternoons mid-June through mid-August since 1938. Classical, jazz, pop, world music. Reserve free tickets online in advance. Bring a blanket and picnic.
